Configure the CMDB Micro-Certification Simulator (Available on Now Learning)

[glenn_pinto]

This simulator, part of the CMDB Fundamentals course on Now Learning, will assess your skills in working with CI Class Manager, Identification and Reconciliation Rules, reclassification rules, CMDB 360/Multisource CMDB, and Data Refresh Rules.

Please use this community article to post questions or issues you find with this simulator before opening a case record. With time this post should provide answers to common questions and inputs.

Thank you and we value your effort to become more knowledgeable on the ServiceNow Platform.

This micro-certification simulator is designed as an adaptive tool to enhance testing and learning through its interactive tasks.

Adaptive simulators operate on three levels:

1. Hardest (Expert Level): Top-level instructions are presented first.
2. Medium (Proficient Level): Mid-level instructions are provided if needed.
3. Beginner Level: Basic instructions are offered at the third and lowest level.

For a detailed explanation of adaptive simulators, watch the "Adaptive Simulator Overview" video to better understand how the simulator functions.

Problem with Task 03: Test Identification Rule. Both scripts ran and produced correct/expected result. Mongoose Web Server confirmed to have a "Runs ::onRuns" relationship with OWA-SD-01 and only one Mongoose Web Server exists. Despite this I get this message when trying to validate task:

"Problem with the number of OWA-SD-01 found - we need to find exactly 1 Server. Did you configure the correct identification rule"

Problem did not occur during the 'Rome' instance, was able to progress past Task 03. Only occuring now in San Diego instance.

[Ronald Tang]

**FIXED**

2 records of OWA-SD-01 exists. Deleting the record that does not have a Runs ::onRuns relationship would fix this problem.

[glennpinto]

Hi Ronald, I will look into this. I don't believe you should have to delete any records to get this to work. Thanks for posting.

[glennpinto]

Hi Ronald, thanks for your msg. It was determined that the instance you are working on is not configured as expected for the Configure the CMDB sim. This has now been fixed, however the sim team may have terminated all sims that were running with the old configuration. If you request a new instance, the new instance will work as expected and will not require the fix you reported earlier. Thank you again for reporting this information so we could remedy it as soon as possible. Thanks

I'm having issues with Task 9 it says task 8 didn't validate properly but It has. Even when running both scripts multiple times. The multisource CMDB table nor the related link appears in the Windows server. Any suggestions?

[Tiphani]

Hi, 

I am having issues with Task 11 on the Configure the CMDB Simulator. I've double-checked Task 9 and watched the video as instructed, but the task keeps failing. Any help would be appreciated! 

[glenn_pinto]

Hi Tiphani, let me know if you are still having issues. If so I can connect with you to review what is going on.  

[VShine]

Hello,

I have problem with Task 2 - Create CI Class. I have completed all other tasks successfully. I can see "Mongoose webserver" class created with provided detail. It is extended from Web Server Class. But when I click "Validate Task", I get 3 observation & fails.

Here is the screenshot for my Mongoose server.

Can someone please point me to what I am missing? 

Here is the error I received:

***** uPDATE:

Sorry for delayed update - If you follow all the steps & complete the task, but simulator is stuck on one task, please open a case with ServiceNow support..... they re run a script on backend and issue was resolved for me.

[Alex Cripps1]

Hi Tiphani, 

Did you manage to do it in the end ? 
i am struggling on task 11 

thanks 

[glenn_pinto]

Alex, let me know if you need assistance. I can look at this with you. Thanks.

[Dona Ranatunga1]

Hello,

I am having 'no show Dynamic Reconciliation Rule' form at Task 14. Pre-requisites are fine.

What could be the stopper please?

DR

[glenn_pinto]

Hi Dona, not sure I follow your query, but if you are saying you do not see the Dynamic Reconciliation Rule option, this becomes available after enabling the Multisource CMDB property. Task 07.

[Dona Ranatunga1]

Hi Glenn_pinto, Thank you for the response!

I completed Task 7 and validated. Now at task 14 - that was 23rd Oct Sunday, 22.

Today, 29th Oct, Saturday I realized that Tokyo module replaced San Diego. I started from Task 1 again, and now at Task 14 with the same issue. When I select Dynamic reconciliation Rule, the Next button still grayed out. Please help me to complete this course.

[ROYB]

Hi Glenn,

I'm currently struggling already in the beginning of the tasks.

At Task 2 Create a new class, the creation of the task under web server is clear. However, when adding the Identifier Entries and adding Class, I get an error. Message

Usage of [sys_class_name] not allowed for identification rules!

I've removed the table and tried again but the same result. Any suggestions?

EDIT:

After a few removals of the tables and retries I've managed to get it working as expected, see screenshot:

[mlapayower]

I'm struggling with Task2 Create New Class. It keeps on failing. I believe it's due to the Dependent Relationships. What should be the Relationship? 

[glenn_pinto]

Task 2 you are just creating the new class as an extension of the Web Server class. The default dependency with the Hardware class is fine. What is the error you are getting?

[mlapayower]

I keep on getting:

Have you created the new class exactly as specifed (u_cmdb_ci_mongoose_web_server) and extended web ...

Have you created a 'Class, running process command' Identifier Entry? Did you extend from the Web Se...

I can provide screenshots to ensure all of the above is filled out accordingly. 

Also, the instructions only says: 

Add Dependent Relationships:

- Confirm Mongoose Web Server has a preconfigured relationship to Hardware

Any hints what should be the Relationship be? I do  have Target class assigned to Hardware.  

[mlapayower]

@glenn_pinto I've figured it out! I've completed Task #2. Thank you

[glenn_pinto]

Would you mind providing the issue that you resolved in case others encounter it? thanks and glad you resolved the issue. 

[Gunjan Dutta1]

Hi I am having issue in resolving  task 09 for CMDB. I created two separate reconciliation rule for LANDesk and ServiceNow. But still getting the error

If any one can help, on this 

[glenn_pinto]

At Gunjan, there is no need to add the filter condition as the discovery source is already defined in the first column.

I'm struggling with Task2 Create New Class. It keeps on failing. I get the following error:

I have created the ID and extended the web server class and still getting the error

[glenn_pinto]

@DG72 based on the error message, it seems that you have not created the identification rule as asked. Can you reverify the following with your identification rule.

Identifier Entries (Use attributes from main table):

- Selected: Class, Running process command

- Allow null attributes: false

- Allow fallback to parent's rule: false

[Community Alums]

just follow the path and in web server add a child and follow the process, it will give you everything basically that is it.

Training at the moment is good

[Neetu_Gupta]

Hi All,

I am having difficulty on 

Task 10: Remediate Duplicates

 Course - CMDB Health Simulator (Tokyo)

[glenn_pinto]

@Neetu_Gupta what seems to be the issue? Also please refer to the "Manage Duplicate Configuration Items" lesson in the CMDB Fundamentals training as it covers this topic in detail. Thanks.

[Hrishikesh Musa]

Hello, I have problem in completing Task 07: Enable Multisource CMDB

I have enabled the multisource properties but validation still failing for the task Enable Multisource CMDB

I been redirected to refer this link - https://docs.servicenow.com/csh?topicname=multisource-cmdb.html&version=latest.
For some reason link is talking about Paris specific features and this instance is for Tokyo.

 Please help.

[glenn_pinto]

Hi @Hrishikesh , the link provided takes me to the Utah content, even though in this case, it is the same configuration as provided in the Paris content. The article states the following:

Enable and configure CMDB 360

• Activate the ITOM Discovery License (com.snc.itom.discovery.license) plugin.
• Navigate to All > Configuration > CMDB 360 Properties. Then, in the CMDB 360 Properties pane ensure that the glide.identification_engine.multisource_enabled (Enables CMDB 360) property is set to true.

[knguyen636]

Hello,

I'm stuck on task 8. How do I navigate to CMDB 360 Data? Please help. Thank you.

[richie-adetime]

I had a problem with Task 7: Enable Multisource CMDB (Utah) even though I activated the ITOM Discovery plugin and enabled both system properties by navigating through the left navigator using sys_properties.list and press enter:

glide.identification_engine.multisource_cmdb_ci_enabled and set it to true

glide.identification_engine.multisource_non_cmdb_ci_enabled and set it to true

Solution:

• Activate the ITOM Discovery License (com.snc.itom.discovery.license) plugin.
• Navigate to All > Configuration > CMDB 360 Properties or just type CMDB 360 in the left navigator.
• Select Yes under "Enables CMDB 360" i.e. glide.identification_engine.multisource_enabled 
• Select Yes under "Enables capturing CMDB 360 data for CIs from CMDB classes (derived from the cmdb_ci class)" i.e. glide.identification_engine.multisource_cmdb_ci_enabled
• Select Yes under "Enables capturing CMDB 360 data for CIs from non-CMDB classes (not derived from the cmdb_ci class) i.e. glide.identification_engine.multisource_non_cmdb_ci_enabled​

[richie-adetime]

Hi @knguyen636 

• Type cmdb_multisource_data.list into the left filter navigator and hit enter

• Search for cmdb_ci_win_server and right click on it and click "show matching"

• 2 CI class records of cmdb_ci_win_server will be displayed for LANDesk and ServiceNow discovery sources respectively.

• Click on Windows Server: OWA-SD-01 with LANDesk discovery source.
  • Right click on the header and select "Configure related list"
  • Search and double click on CMDB 360 Data under available slush bucket and save
  • Scroll to the bottom of the OWA-SD-01 record and select the personalize list under "CMDB 360 Data" related list to select Col 36 and save
  • Save the OWA-SD-01 record and validate your task 
• Please mark helpful or accept solution so that it helps others with a similar question

[glenn_pinto]

@Hrishikesh Musa looks like folks have provided you with correct things to try. Enable the ITOM Discovery license plugin and enable the property for glide.identification_engine.multisource_cmdb_ci_enabled. I would just double check the ITOM Discovery license displays as Installed and for the system property that it is set to true with no spelling mistakes. The other properties are not needed for this use case since we are not working with non-cmdb tables. Note: as of the Utah release, the Multisource CMDB is known as CMDB 360. It is one in the same.

[Amena Bashir]

I am stuck in task 2
running process command is not available in attributes while creating the mongoose web server for configure the cmdb certification in servicenow

[arai keigo]

I am trying to create an identification rule in Task02, but I cannot add a Class attribute because Class does not appear in the attribute choices.
Why can't I select the attribute Class even though it exists?

[pratiksha5]

@arai keigo Try refreshing the page. 

[Amena Bashir]

@arai keigo, select the option "dependent" then check the attributes. the "Class" attributes should be there

[glenn_pinto]

@Arai I just tested and 

Amena Bashir is correct, if you don't choose dependent for the Identifier, then class does not display. So edit the identifier and make sure it is dependent, and then class will be available. Thank you

Amena Bashir

[glenn_pinto]

Amena Bashir did you find running process command, it should be there?

[Amena Bashir]

no I didn't find it 

[glenn_pinto]

@Amena Bashir you created a dependent identifier, and after created an identifier entry and running process command does not display? Can you send screen shot. Thanks.

[Amena Bashir]

Here is the screenshot the  running process command is not available

[Raghav Kakkar]

Hi @glenn_pinto!

I need help with "Task 13: Build Query with Non-CMDB Table( Utah)" from CMDB Health Simulator.

I have created a query using CMDB query builder and it's giving me the right result as well. But the validation still fails.

After raising a support case, I got to know that the validation is done on the sys_db_object table, where the system expects a record with the name "cmdb_qb_result_base" and Label "Critical Incidents with No Owner".

While the Query from Lab 12 (Windows 2012, 2016, 2019) has populated the record, but the query from Lab 13 (Critical Incidents with No Owner) is not creating any record in sys_db_object.

Please refer the SS below.

Any help is appreciated! Thanks in advanced 🙂 

[glenn_pinto]

@Raghav Kakkar regarding task 13, the validation is based on the value you enter into the description field. Did you enter and a value in this field and save it. This step is described in the following:
"- In the Description field, enter the number of records returned and then save the query again." If you did enter a value in this field, what value did you enter?

[Raghav Kakkar]

Hey @glenn_pinto, yes, I did add the value "6" in the description. However, I deleted that Query and created a new one. This time I saw the record in sys_db_object table but the label did not get populated correctly and it said, "Query Object". So, I renamed it manually and got the validation.

[Jack19]

I am having issues with Task 5. I have followed the instructions faithfully but the graphic doesn't match and the validation fails every time. I have un-done and re-done it several times with no luck. Here is proof that I added the required fields:

I ran the dashboard job (multiple times) yet the result continues to fail with this message:

What am I doing wrong?

[Jack19]

I also apparently messed up the de-duplication process, as I can't get Task 10 to validate either.

[jungjo]

Task 2 i am stuck , does not validate. Looked aboved and did not see a fix.

here is what my instance has...THX in Advance
