Use the Event Management
self-health monitors to track Event Management features and resolve
issues.
Monitor Event Management to detect and resolve
issues
Enable the self-health feature to help detect and troubleshoot Event Management health issues. Some configuration is required before the
self-health feature can display meaningful data. Once configured and the related
scheduled jobs are enabled, the Event Management dashboard displays data
that is automatically collected and calculated on a recurring schedule.
Note: Event Management Dashboard is not supported for new instances in the Orlando release. However, instances upgraded from a
previous release that use Event Management Dashboard can continue to do
so.
The self-health feature creates CIs in the CMDB to represent the
components of the self-health service. Use the provided monitors to monitor and track
the health of services and Event Management features. Event Management self-health can:
- Trigger alerts when there is an issue with Event Management.
- Display the ServiceNow Event Management
application
service on the Event Management dashboard. Use the dashboard to view
alerts by application service, technical service, and alert groups. You can
double-click a tile to view a map representation of the service.
- View a map representation of the ServiceNow Event
Management
application
service to see the relationships between CIs in the ServiceNow Event
Management
application
service.
Set up
Ensure that the Event
Management — self-health monitoring (evt_mgmt.self_health_active)
property is set to Enable to use the Event Management features that
handle issues with the Event Management application
itself. For more information, see Start or stop self-health monitoring.
Self-health monitoring process
workflow
After the Event Management — self-health
monitoring property is enabled:
- The ServiceNow Event Management
application
service is automatically created.
- Jobs are automatically scheduled to run scripts that configure what must be
monitored.
- The Monitoring States [em_monitor_state] table is updated after each event run
that the configuration scripts trigger.
- Monitor the alerts that are generated. The service displays the status of the
monitored entity. For example, alerts are displayed in the Event Management dashboard, Alert Intelligence, or All Alerts
list.
- Resolve the alerts according to the underlying issue, for example, using
Quick Response.
Jobs scheduled to process scripts
The jobs
scheduled to run by default after the Event Management — self-health
monitoring property is enabled are:
- The
Event Management - Insert Health Monitor scheduled job which runs the scripts.
Determine what must be monitored by adding to, or modifying the script in this
job which runs once every hour. After the job has run, you can view the
ServiceNow Event Management
application
service.
- The
Event Management - Update Health Monitor scheduled job which runs the update
scripts. This job runs once every minute.
