Request to Activate Scheduled Jobs and Monitor System Performance

[siddheshagn]

Hi All,

I’d like to request activation of the following scheduled jobs:

• CMDB Health Dashboard – Relationship Score Calculation
• CMDB Health Dashboard – Relationship Compliance Processor

We are initiating relationship calculations from this point forward. ServiceNow has confirmed that the slowness previously caused by these jobs in Xanadu has been resolved.

Additionally, I came across a dashboard titled ServiceNow Performance, which appears to support instance performance monitoring. However, I’m unsure how to filter data by specific date and time.

Is there a recommended way to monitor system performance on a regular basis?

Thanks,
Siddhesh Agnihotri.

Hi @siddheshagn ,

As per my understanding, you can follow below steps which might be helpful

1. Activating CMDB Health Relationship Jobs
The jobs you mentioned are out-of-box scheduled jobs that calculate relationship health in CMDB:
* CMDB Health Dashboard – Relationship Score Calculation
Calculates the relationship score for CIs based on the rules configured.
* CMDB Health Dashboard – Relationship Compliance Processor
Evaluates CI relationships against compliance rules (e.g., missing relationships, invalid relationships).
How to Activate
1. Navigate to System Definition → Scheduled Jobs.
2. Search for the jobs by name.
3. Open the job record.
4. Check the Active field → set it to true.
5. Save.

Best Practice Tip:
* If you’re in Prod, do a phased activation — run them once manually during a low-usage window, validate performance, then keep them active.
* Monitor job duration in System Logs → Scheduled Job Logs.

2. Monitoring Instance Performance (ServiceNow Performance Dashboard)
You found the ServiceNow Performance dashboard. This comes from the Instance Security Center / HealthScan / Performance Analytics for Platform Metrics depending on your version.
Filtering by Date/Time

* If it’s Performance Analytics (PA) dashboard:
* Use the time series widget filters → top right of each widget.
* Or click the gear icon → Configure → Add filter (e.g., created on between X and Y).
* If it’s Instance Security Center → Performance dashboard:
* Filtering is usually limited to last 7 days / last 30 days (predefined ranges).
* For granular filtering, use the underlying table:
* sys_instance_performance_metric (stores CPU, DB time, transactions).
* Build a custom PA indicator or report if you need exact date-time filtering.

3. Recommended Way to Monitor Performance Regularly
Here are best practice approaches:
Use Built-in Tools
* Instance Security Center (in Now Platform): gives real-time monitoring of nodes, DB time, transactions.
* System Logs → Stats: check stats.do for a quick snapshot.
* System Diagnostics → Node Status: to see JVM/Memory usage.

Automate Alerts
* Set up Event Rules + Notifications for thresholds like:
* Slow DB transactions.
* High memory usage.
* Long-running business rules/flows.

Use Performance Analytics
* Create PA indicators on tables like:
* sys_instance_performance_metric
* syslog_transaction
* Schedule daily/weekly scorecards.

Suggested Next Steps
1. Activate the jobs (start with UAT / Test instance first).
2. Monitor job run duration & system logs.
3. For performance monitoring:
* Use Instance Security Center for real-time.
* Use Performance Analytics for historical & filtered analysis.

Go to Health Dashboard > CMDB Health Settings Button(On Top Right) > Scheduled Jobs

Check CMDB Health Dashboard - Relationship Compliance Processor and CMDB Health Dashboard - Relationship Score Calculation.

Click on Execute Now button before activating the schedule.

You can use the View Dashboard Link the scheduled job form to monitor the performance.

Hi @siddheshagn 

• Go to CMDB Workspace.

• Open the Management tab.

• On the top left, click CMDB Health Settings.

• A new page will open.

• In the second tab (Scheduled Jobs), open the required job.

• Click Execute Now.

Additionally, I came across a dashboard titled ServiceNow Performance, which appears to support instance performance monitoring. However, I’m unsure how to filter data by specific date and time.

Is there a recommended way to monitor system performance on a regular basis?

Atul: 

Yes, it is recommended to keep checking the system performance. This helps identify whether things are going well or if improvements are needed.

• Start with the areas marked red, since they require immediate action.

• Discuss with the team whether the issue is due to governance, code quality, or access problems, and fix those first.

• After that, move on to the amber areas for further improvements.
