Self-health monitors for Event Management

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 Service Operations Workspace displays data that is automatically collected and calculated on a recurring schedule.

注:

Event Management Dashboard is not supported for new instances in the Paris release. However, instances upgraded from a release prior to Orlando 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 services in Service Operations Workspace. Use Service Operations Workspace to view alerts by application service, technical service, and alert groups. You can double-click a tile to view general information about the service.
  
  

  

  
  
• Click Service Details to view details of the service.
• Click Service Map to view a map representation of the ServiceNow Event Management application services to see the relationships between CIs in the ServiceNow Event Management application services.

Self-health monitoring process workflow

After the Event Management — self-health monitoring property is enabled:

1. The ServiceNow Event Management application services is automatically created.
2. Jobs are automatically scheduled to run scripts that configure what must be monitored.
3. The Monitoring States [em_monitor_state] table is updated after each event run that the configuration scripts trigger.
4. The alerts that are generated are monitored.

   The service displays the status of the monitored entity. For example, alerts are displayed in the Event Management dashboard, Service Operations Workspace or All Alerts list.

You can resolve the alerts according to the underlying issue by using Quick Response on the standard platform interface. For details, see Apply a quick response in an alert.

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.
• The Event Management - Update Health Monitor scheduled job which runs the update scripts. This job runs once every minute.

• Start or stop self-health monitoring
  You can control the starting or stopping of the self-health monitor feature by configuring the self-health monitoring property. The first time that the self-health monitoring property is enabled, it automatically creates the ServiceNow Event Management application services.
• Configure the Event Management - Insert Health Monitor scheduled job
  Determine what the Event Management - Insert Health Monitor scheduled job is to monitor. After the job runs, you can view the ServiceNow Event Management application services.
• Monitor self-health with domain separation
  Use domain separation to enable self-health to display Event Management health issues that are based on data, rules, and settings from the logged in user domain. The selected domain must not contain any child domains.
• Configure a self-health monitor
  You can configure a self-health monitor to track Event Management components and see that they do not exceed the specified threshold.
• Create a self-health monitor to use custom health monitor script
  You can create a self-health monitor to use custom health monitor script to monitor specified Event Management components.
• View the Event Management self-health application services map
  You can view Event Management application services maps to have a visualization of the data on configuration items (CIs) that comprise this service, and the relations and connections between these CIs.
