Overview

Jump into the world of ServiceNow with Atul G as he guides us through the essential parts of the Configuration Management Database (CMDB). This database is depicted as the backbone of IT management that organizations tirelessly work to refine and utilize effectively. Atul emphasizes that the more fundamental understanding one has of CMDB, the easier it is to apply practically in real-world situations—aligning technical functions with organizational needs seamlessly.

Within this session, a spotlight is cast on the need to distinguish between configuration items (CIs) and assets. While both play roles in service delivery, their definitions and implications diverge significantly in practical applications. Atul uses everyday analogies—like owning a car or organizing furniture in a showroom—to clarify these distinctions, enhancing the learners' grasp of somewhat abstract IT concepts.

Understanding ServiceNow’s categorization via classes is another pivotal concept dealt with in the session. With hundreds of class tables, ServiceNow structures and streamlines IT management, akin to a departmental store organizing its sections. By breaking down this intricate structure, Atul conveys how classes in CMDB support efficient data management and operational functions, offering insights into how IT components are logically grouped and maintained for optimal service delivery.

Batch 13 | Day22 | CMDB Overview - Classes Transcription

00:00 - 00:30 good morning everybody and once again welcome back in today's class today we are on the day number 22 and we are starting a new topic which is something different than the usual topics because this particular concept I can say is the heart of service now or or if I say that it is
00:30 - 01:00 something which every company want to improve every company want to use and it is not that much [Music] easy to understand this concept means there's a lot of confusion lot of if and buts in this concept also
01:00 - 01:30 important point is that this concept more you understand fundamentally is easy for you to be used in the Practical life okay so we are going to discuss about a topic that is called cmdb okay we're going to discuss a topic called cmdp
01:30 - 02:00 CM DB total three topics we are going to discuss cmdb assets and CS DM for the cmdp and asset we will have
02:00 - 02:30 some practical work like how to create how to maintain how to update but csdm it will be a one day topic and moreover very high level for you guys at point of time the reason being because this concept is still in the evolving phase service not doing upgrade
02:30 - 03:00 updates on this and there are a lot of customers who are using this particular concept even though I work practically in this concept and we implemented the csdm okay so now what is cmdb cmdb stand for the configuration
03:00 - 03:30 management database four words three words we know management we know database we know let's combine this one okay but we are not known that what is the meaning of the configuration or we call this as a okay
03:30 - 04:00 SCI which means configuration item okay which means configuration item what is configuration item any idea have you he this word earlier
04:00 - 04:30 configuration item yeah like Hardwares only Hardwares yeah I guess okay many for I um I R I've seen it previously mhm yeah so it's like they're
04:30 - 05:00 like um it resources or something but but what is what is CI Hardware is an example what is the meaning of a CI like my son says what you drinking I said it's it's a tea what is tea I said it is something which we can take when we little tired to refresh our body even though it's not
05:00 - 05:30 a good but still be take no no that's fine you're giving me type you're giving me other words but what is p so what is CI C okay hard is the one thing okay let let me go to the definition so any component which help you
05:30 - 06:00 to provide your services to the customer sorry actually is anab not joining us today anab will join maybe he he's kind of yesterday so let me give a call him again or maybe he's in thought that class will start at 6:00 but we move it 15 minutes back or maybe he was out for a long weekend maybe tired or something
06:00 - 06:30 let's that's fine okay so CI means any component which help or support to provide the services now if I take a normal example in our house we have a lot of things we have a chair dining bed
06:30 - 07:00 washing machine microwave gas Stu these are these all are the components which help us to make our life easy they provide the services to us and we using them so where these all the configuration items are stored is called the configuration management
07:00 - 07:30 database let me take you on the actual definition of CI in service now see any computer device software or service in the
07:30 - 08:00 cmdb you are saying Alia that only Hardware no any device any computer any device any software as well like you are using Microsoft Word to to do your documentation work is not a CI yes it is a CI because it helping us to provide the
08:00 - 08:30 Services right and every CI has some of the attributes like if I take example of 5 ft 6 in a well-maintained guy earning that much amount leing in this area hobby is this parents name is
08:30 - 09:00 this sister name is this job profile is this designation is this compan is this these are the attributes of a user called earner in the same manner a CI also has the attribute what are the attributes of of a laptop
09:00 - 09:30 laptop size laptop color Ram hard disk processor motherboard installed software and many more this is what this is the attributes of a CI now the question come if if this is a
09:30 - 10:00 CI then what is asset what do you mean by the word asset tell me what is the word or what is the meaning of the word asset h
10:00 - 10:30 Alisa what is asset come on give me the answer what is asset and I said in the beginning this particular topic is more on the fundamentals functional and less than on the technical part
10:30 - 11:00 and now what is asset sahil what is asset asset is a something I think which can be owned by an individual something tangible okay now if Microsoft is creating the
11:00 - 11:30 softwares will this not asset for Microsoft Microsoft Word Excel Power Point office 65 H the license will be an asset for them then then but AR says something which is tangible and these are the intangible right you cannot touch you cannot feel like collection of software and Hardware
11:30 - 12:00 data then what is what is the difference between CI and asset what's the difference between what what is the difference between CI and asset if I take sahil words a collection of hardware and the software then what is the difference between CI and asset C is a
12:00 - 12:30 value what value collecting some value what is asset asset sofware and Hardware these are the model categories for I can say for your CIS so to clarify to simplify this
12:30 - 13:00 particular thing asset is something which has a financial binding attest okay now tell me Arab Alisa and sahil went on a trip okay together they all carry their iPhone and MacBook okay you guys go and purchase let's say
13:00 - 13:30 a water bottle maybe some tissues some snacks which is the asset for you is this laptop and the MacBook is asset for you or the water bottle tissues or the snacks you purchase that is asset for you definitely
13:30 - 14:00 a laptop and iPhone why because those have the financial bindings which you can resale and get some money back but once you drink the water you cannot get it back once you eat the snacks you cannot get it back once you use that tissues you cannot get it back I'm not saying that that these are not the asset these are I can say these
14:00 - 14:30 are also asset but these are the consumable assets which you consume so the major difference between CI and asset is this asset is track the financial contractual and inventory details of the hardware device and as well as the non assets
14:30 - 15:00 your house your building your car your bike your jewellelry are your assets are your assets because they have the financial Bing they have a life you cannot drive a car which is old than 15 years because 15 years is a life it's over now you have to be scrap
15:00 - 15:30 it clear I want to clear this concept because when we see one more term or when we go for one another example I want the answer for this one as well again clear sahil Alisa and Arna what is CI and what is asset any doubt any question
15:30 - 16:00 not really good now the thing is that Atul why we need CI and let's let's come to the CI why we need CI in our system what is what is the need what is the purpose now here this example and let me know your thoughts on that particular part okay let's say Arab went for a business trip and stay he
16:00 - 16:30 stay in sorry so sorry yeah can I um um so CI and asset are they kind of are they interrelated they are interated yes because you um you said configuration item doesn't necess have to do with Hardware it comprises of everything within I think it platform
16:30 - 17:00 but the definition you gave on asset it said something only about Hardware so that's what is confusing so so only only not only basically not only has a hardware but has a financial bindings Financial tracks I give you one example to understand this part do you have a car maybe not here in your hometown in your home country yeah okay that car if that car is parged in your
17:00 - 17:30 parking see the example if that car is parged in your parking mhm that is the asset for you right yes it is but if that car is in the mechanic shop then it is a CI for that particular person or even for you okay why because you're using that car are to provide the services to your
17:30 - 18:00 life to travel to commute you are using that car so a CI can be a CI can be a asset see the car is still same the car is still on the Elizabeth Daniel name the owner of that car is still Elizabeth Daniel either it start it's standing in the parking or it's standing in the mechanic place or mechanic shop the only thing is that
18:00 - 18:30 when it is in a parking you proudly say hey this is my car I own this car but when that car go to the mechanic part mechanic shop then it become a CI you did not say that hey this is my asset you say boss my car is not working properly there's some issue in my car right yeah because issue and now now the second example which I was
18:30 - 19:00 about to give the same thing let's say went to a business trip and he stay in a hotel and there's nothing to be hide that nowadays the hotels are so much digital technical formats specifically they put a lot of new things which even I don't know a lot of part so Arab entered in the room he find something good but he don't know that how to use or why it's not working
19:00 - 19:30 properly he don't know that what is that particular thing called he called to the housekeeping and say hey I just checking in this room but this is not working that housekeeping person says sir sorry to uh hear your feedback but what is not working hey something which is in the round shape has some some kind of uh look like the fan is not
19:30 - 20:00 working sir I'm not getting it are you talking about the heater or are you talking about some u stand fans or what no no it's not a fan but it's look like a fan only now see the problem because he don't know that what this concept called what this product called and this is what the CI is here whenever we raise any incident
20:00 - 20:30 change or problem CI is the one thing which tell us that on which component we have a issue now let's go to the lon language okay anab got married he and his wife is staying at some other because of his job commitments
20:30 - 21:00 okay he bring the new AC and bring and ask mechanic to fit it mechanic came AC has been fitted properly okay it was going very well he went to office in the morning and his wife called to the mechanic okay and there there's nothing I'm I'm putting wrong here just should we give example okay and's wife called to the
21:00 - 21:30 mechanic or that particular shop person hey uh you came a two days back to fit something on in our house but that something is not working Madam number one what is that something mean something what what is that something it's some like AC or fridge or cooler or OV or gas St or fan or tublight what no no no no you you remember that you came and there's some
21:30 - 22:00 there's a very weird noises coming in that something ma but what is that something mean here what is that something means until unless you will not tell or you why did not tell to mechanic that that something means I'm talking about air condition air conditioner mechanic will not understand that where is the issue actually this is what the purpose of maintaining the CIS if you come here and you
22:00 - 22:30 see incident cre this is a configuration item so if I put like this these all are my configuration This Server is my configuration item because This Server help me to provide the
22:30 - 23:00 services now it can be virtual server now it can be physical server but it is a CIA for me anab says Atul you are in UK I said yes hey I'm traveling to UK can you book um hotel room for me for the business trip for the 5 days you have any references in your city H I can I can do that part I call call to one of my non person and say hey my friend is coming can you
23:00 - 23:30 book a hotel room this is a virtual part virtual support I know you're my best friend I I don't worry I'll come for your pickup in Manchester the or the London don't worry I'll come for a pickup this is a physical support but I'm still a CI sorry right I'm not well I'm not able to come here CI is not working right so this is the place this is the
23:30 - 24:00 heart of any industry we say I am I am able to implement itm for my customer if we are able to bring and implement the cmdb on that particular place then we say that yes I'm able to implement itm for my customer for the next two days approxim imely today and tomorrow's
24:00 - 24:30 mainly these are the concepts which you have to be understand and cmdb is like a big c more you deep more you dive okay now this is what the basic concepts let's come to yes go ahead please can I mean can is it like all CIS are I mean if I say all CIS are assets
24:30 - 25:00 too will I be wrong or can there be CIS which which are not assets uh practically if I say answer is yes but if we talk about service now then answer is no okay we will will have have this concept that what C what CI ish service now considered as a asset okay okay okay mhm now now okay tell me let's say you purchase a new car
25:00 - 25:30 okay you go to the showroom you pay the amount and you get the keys and you bring the car on the road now it is a Ci or it is asset I think is the asset sorry sorry I just a minute Ela what you said the kai is the asset and maybe the break brakes The Brake Part all the um the gear the horn all those
25:30 - 26:00 things are the CI the car but complete car is but but complete car is asset right c yeah but the complete car is the assets so it a Ci or asset still I'm confused no so the car is the asset in my opinion and the brakes the brake pad the hor the chair all those things that like the eyes of the car so just like maybe service now is an asset
26:00 - 26:30 an incident um sorry the other little things that make it up are like the CIS okay got it I think it's a CI because it's working and based on what you explained before if it's in your parking it's it's an asset but if it's out on the road um if it's working it's considered as a CI that's what I understood so so it means it it is clear that till the time this car was in the
26:30 - 27:00 showroom it was a CI only as soon as you purchase it it become asset for you and CI as well so service now use a fundamental here which says that Hardware considered as a asset so so give me some time I I'll come to this concept little later because before that we have to understand One More Concept here okay
27:00 - 27:30 let's say you three went to a Furniture showroom a very big furniture showroom that showroom has table chair office table kitchen table kitchen chair bed sofa dining small tables for serving purpose side
27:30 - 28:00 tables Garden tables garden chairs kids table kids mattresses now if I say okay guys oh my God this is a very big showroom I want to purchase something for my kid at will go to the kids section it means we have to be classify
28:00 - 28:30 these items in a category if you want to purchase something for the dining room go to this particular section where you will find only dining related Furniture if you want to purchase something for the bedroom go to this section you will find all the stuff related to bed do side tables bed
28:30 - 29:00 wardrobes and all the things if you want to find out something for the op this is a office related Furniture then go to this section why we have these sections so that for the company easy to maintain easy to store and for the customer easy to search
29:00 - 29:30 right in the same manner in the IT industry we have a lot of components I give example I have a Wi-Fi router I have some old router as well okay then I have a speaker external speaker I have a laptop I have a desktop I have a keyboard mouse
29:30 - 30:00 headsets camera bluetooth camera sorry external camera then I have few components related to my my laptop Bluetooth um Point Chargers adapters are there now my wife says hey you you are making so much so much mess on your deck please make it simplified make it
30:00 - 30:30 make make it clean what I will do I will keep Wi-Fi routers in a one box I'll keep all the speakers external speaker small speaker big speaker in a one place I'll put all the headsets in a one place all the charger in a one place all the laptops in a one place and I'll put the sticky note Wi-Fi stuff
30:30 - 31:00 speaker stuff headset stuff charger stuff and laptops so that I can easily maintain I easily record easily see that what's the stuff I keep it at what place this is what service now says here service now says we have a a number of items which help me to to provide the services
31:00 - 31:30 router networks your switches your servers your database and if I go more in the database I have my SQL SQL Server mango DBS if I go to servers I have a Linux server Windows Server ux servers X servers multiple servers are there so service now classify this as a classes
31:30 - 32:00 service now says you cannot remember everything let's make this as a class remember the example of the furniture now these are the classes if you want to go for the bedroom furniture this is the bedroom class if you want to go for the kids section this is a kids class where you will find only and only stuff related to that particular concept only so now if I come here and show you
32:00 - 32:30 something amazing search for the CI class manager and in the other one I'll open the tables
32:30 - 33:00 H this one let me come on this then I I'll go to this particular part in the table like we have a task table now there must be table right so cmtp and percentage this configuration item
33:00 - 33:30 this is the core table because it get extended from the base configuration table let me show you this table as well this is the base table cmdb and cmdb _ CI is the core
33:30 - 34:00 table so like we have a task table now we have a cmdb table only cmdb is a base and cmdb CN table is the code table now if I go back you want to know that how many tables we have in service now
34:00 - 34:30 we have 1,200 tables only and only for the cmdp and if you see that all these tables are extended from the other tables and these are nothing these are the classes cmdb uncore
34:30 - 35:00 C see sorry I guess that was a little bit more so thousand tables are there which are classes table I can say so don't be surprised what this classes means now I'll show you in the little bit graphical format these are the
35:00 - 35:30 classes computer is a class air conditioner is a class server is a class database is a class router is a class switch is a class I still remember when I was very in the young age 15 16 years or 14 15 years I usually go to my father's office he retired from the government job and in the in his office the
35:30 - 36:00 computer was newly introduced so they have a separate room for the computer which was fully air conditioned you to take out your shoes outside and then you can go and I go there and just see that how this computer look like and if I get some chance I play the game as well to run that computer room they have five or seven AC's installed and and that time it was very big deal that oh my God you have 7
36:00 - 36:30 is's desktop old black screen desktops how this air condition has been mapped or maintained we have a separate class here so now if I show you that computer see computer computer room computer room AC personal computer and the computer peripher these are the five different classes
36:30 - 37:00 personal computer is like your desktops computers are talking about the laptop specifically computer room how many computer rooms we have in a building if I say they working in a company okay it's very big company 3 four five Towers they have 10 10 floors they have if you get a chance visit those those
37:00 - 37:30 floors and you will see that almost on every floor there is a room which is called the um Hub room or the network or the server room where nobody's allowed to go inside only authorized persons are allowed to go how they're maintaining it in the system this is the way now if I show you the
37:30 - 38:00 server see Server is the parent class and these many type of servers are the child I'm sure many of us even did not hear about these type of server cim server Ops server ISS server I don't know truly I don't know what type of server these are database see Cloud database mle databas catalog dat instance cloud
38:00 - 38:30 computing database and clusters so service now say that these are the hierarchy now I'll show you about the hierarchy which question you put computer and let's open this so computer is a part of the hardware so Hardware is a model category again model is the two hardware and the
38:30 - 39:00 software but here they consider mainly the software let's see do we have anything on the software as well so in the software we have these thing application software desktop software inst software and there is a part of the software as a model and all these are provided out of box only right yes
39:00 - 39:30 correct so now now we can imagine that how big the data model they're using to maintain and providing everything to out of the box thousand table is not not a small deal oh yeah right and if you read about thousand table I'm sure that none of us having idea more than 10 or 15 tables which is known to us right so now if I come here for the
39:30 - 40:00 computer in the computer we have these many sub [Music] classes right now if I say personal computer see configuration item under that we have we have Hardware under that we have a computer that we have a personal computer and what is the table
40:00 - 40:30 name is PC Hardware PC Hardware what are the attributes it has it has 107 attributes how many it's drived drived means how many it has get from the previous class from the p all he got from the parent
40:30 - 41:00 only identification rule how you will identify so we will not go in this much depth because for the admin we have to just understand that what is cmdp identification rule reconcile rule are the things which is required when you go a deep D of the cmdb completely maybe some other course or when you go for the discovery or item perspective then you need to be
41:00 - 41:30 understood basically identification rule is used when we do the discovery when when we are finding our components on the network let's not go much in depth reconcile if Anna brings some data to me ala brings some data to me how I'll make sure that it is not a duplicate
41:30 - 42:00 one so we have to be defined some parameters this is what the reconcilation in the banking sector in the last month of the financial year they do the reconcile just to make sure that the balance must be tell then the relationship it is important this is this is concept we will discuss in depth
42:00 - 42:30 tomorrow okay and this is the CI list that how many CI we have as of now we don't have any CI here now these are the basics has been clear let's let's take you on the Practical part come here and search for the computer okay under the base item click on the
42:30 - 43:00 computers and we are going to be create a new computer CI we are going to be create a new CI because service now said before before or service now say it is a BRI it is a best
43:00 - 43:30 practice don't create a asset first specifically for the hardware cases create a CI first and I will create the asset for the same CI as per my defined rule so like you can see the asset option here let's say if I have a server Exel
43:30 - 44:00 one we have a asset here but if I go to some other class dp2 it don't have any asset so how it is
44:00 - 44:30 becoming that you will see that why at why only few tables are showing here not every table has a asset because this is what the service not defined in the background how this thing work we will see but not today tomorrow now we will see this computer what is my computer name LNG batch 13 Tag I want to put a tag on my
44:30 - 45:00 computer 1 2 3 4 5 6 7 8 9 who is the manufacturer manufacturer is Apple okay what is real number of my computer this what is the model idle MacBook Air okay if you want to put the OS domain
45:00 - 45:30 operating system so so these are the attributes and I'm telling you one more thing don't think that only these attributes are available on this table no there are more attributes available on this particular table if I go back here let let me duplicate
45:30 - 46:00 this right click configure all not this one sorry because this don't configure and form design or we can go to table as well sorry my so these many fields are
46:00 - 46:30 available see more than 100 Fields available on this particular table now what we will do we will click on the save and now we have to wait for some time that my asset record generate a automatically my asset record generate
46:30 - 47:00 automatically why automatically how automatically that we will discuss there are some rules there are some scripting which run in the background maybe I'm not sh to share a lot of thoughts about the cmdb but this is what the basic point which I always share in my in my training that how these assets get
47:00 - 47:30 created it it take little time because a job run in the background okay now if I show you oh it will take time so if I show you something here and search for the business rule
47:30 - 48:00 and open this and other tab let me close everything else not required there is a business rule which create the asset asset C is anything called create asset check check asset and CI create asset on insert yes
48:00 - 48:30 see this is the code which run and create the asset for my CI see still I'm waiting for this one it take little time to be get created but let's see from where this logic is becoming this logic is coming from this
48:30 - 49:00 particular part this come on yeah seven line code no this s code has a one thing which is important is something this asset and CI and the sync property
49:00 - 49:30 I'm not able to alter what the shortcut key a shortcut key to open this so there's a rule run in the background which read all this information name tag serial number Mark model and manufacture and on the basis of that it create an asset for
49:30 - 50:00 my CI let me open the others which is already built up it's taking some time okay and now let me add a section and don't get confused that's fine what
50:00 - 50:30 manufacture we have we need asset tag we need serial number we need the model ID let's remove this let's remove this bring this here and see see we have the assets for this so something similar we are waiting for our asset to be get
50:30 - 51:00 created sometime it really take time actually not sure why something first time I'm running or what so if you see here that there is a computer any IBM they have a asset tag like this they have a manufacturer like this they have a sale number like this they model ID like this so with the combination of asset
51:00 - 51:30 Tech and model ID the asset get created and this is created because in the background this business will run syn let me let me see something else as well this is the one which is run actually create asset and there's one more which Run for the
51:30 - 52:00 synchronization create asset generate asset not this one syn say not this one sink said I'm Bing if that get credit that will be more good for us to be move forward come on it's taking so much time practically should not let's create a
52:00 - 52:30 new computer okay come here LNG l 1 2 3 4 5 6 Cal number NG this Lenovo model
52:30 - 53:00 ID Lenovo TD this okay and submit and if I come here and search LNG I'm waiting for these to be get created J did not take this much time actually okay now but next here let me come back on my this one it
53:00 - 53:30 will it will get credit don't worry now for this CI I have a asset as well okay now tell me one thing if enough purchase a car and that car is standing in the parking and that car color is red if that car standing in the mechanic
53:30 - 54:00 shop will the color of the car will get change no right it will be still red until let you specifically ask them or ask him to change the color but it will be always red it means the there are few attributes which are
54:00 - 54:30 common basic example Arab when arav was Bachelor he was just parents called he's my son but now he get married his in-law says that he's our son is this change the identity of Arab
54:30 - 55:00 AR is still same AR is still behaving the same still having eating the same still working the same manner so the concept is that the parameters are common between CI and setet but there are few parameters which are different the car which is standing in the parking it belong to a even though the car is uh
55:00 - 55:30 still a car is available or standing in the garage it is still belong to un only owner did not get change either it start standing the parking or it's standing in the mechanic Place why saying this much time you are H it okay go so now if I open this
55:30 - 56:00 asset this is asset and this is on the table Alm Hardware this is CI on the table CM dbci don't get confused s and hard asset and CI both stored in the different different
56:00 - 56:30 tables not in the same table so don't get confused now if I change the assign to alander pepic and see who is the assigned to any I'll click on the
56:30 - 57:00 save now if you go in the asset this get change how how this get change I click managed by here oh it's a sing name okay Ellie
57:00 - 57:30 betner save come here okay they don't have this field on the form let me show you that because this is the thought for today managed
57:30 - 58:00 by on by or managed by on by supported group let and bring on the top and save and now you can see if I put on
58:00 - 58:30 by Abraham Lincoln and save come here how this thing are working now maybe you have a question at come on why you making us a fool same product right same same component car is car either you see from the front side or see in the back side it is still
58:30 - 59:00 called as a car that's fine but how this data is getting updated that is the my that is my question how this data get updated so this is thought for you for today tomorrow we will see that what is working in the background which making these things
59:00 - 59:30 possible even though you are not a technical guy you don't need to understand that part but still very interesting concept we are going to be discussed tomorrow so we will see the CI and asset mappings field level mapping state level mapping status level mapping and the relationship part clear everybody any doubt any
59:30 - 60:00 question any clarification and now Alisa sahil and all clear and all confusing as well yeah okay so to clarify these things definitely you to be read a lot read the concepts on the service now Community or
60:00 - 60:30 maybe in the now learning the basics of cmdb because as I said that I can give you very high level I cannot take you the more deep and deep and deep and deep so this is the basics we need to be understand here and then we can move it forward so now let me stop the recording and we'll take a quick attendance now
