List of event sources

Sources of events are displayed in the table under Source status → List of event sources. One page can display up to 250 sources. You can sort the table by clicking the column header of the relevant setting. Clicking on a source of events opens an incoming data graph.

You can use the Search field to search for event sources. The search is performed using regular expressions (RE2).

If necessary, you can configure the interval for updating data in the table. Available update periods: 1 minute, 5 minutes, 15 minutes, 1 hour. The default value is No refresh. You may need to configure the update period to track changes made to the list of sources.

The following columns are available:

• Status—status of the event source:
  • Green—events are being received within the limits of the assigned monitoring policy.
  • Red—the frequency or number of incoming events go beyond the boundaries defined in the monitoring policy.
  • Gray—a monitoring policy has not been assigned to the source of events.

  The table can be filtered by this setting.

• Name—name of the event source. The name is generated automatically from the values of fields configured in the event source identification settings.

  You can change the name of an event source. The name can contain no more than 128 Unicode characters.

• Host name or IP address—name or IP address of the host from which the events originate if the DeviceHostName or DeviceAddress fields are specified in the event source identification settings.
• Monitoring policy—name of the monitoring policy assigned to the event source.
• Stream—frequency at which events are received from the event source. Depending on the selected monitoring policy type, it is displayed as a number of events (for a policy of the byCount type) or as a number of events per second (EPS, for a policy of the byEPS type).
• Lower limit—lower boundary of the permissible number of incoming events as indicated in the monitoring policy.
• Upper limit—upper boundary of the permissible number of incoming events as indicated in the monitoring policy.
• Tenant—the tenant that owns the events received from the event source.

By default, no more than 250 event sources are displayed on the page and are available for selection. If more event sources exist, to be able to select them, you must load additional event sources by clicking the Show next 250 button in the lower part of the window.
Group operations with the Select all option work only with currently displayed event sources. For example, if you click Select all, and only 500 out of 1500 sources are displayed in the list, bulk actions to download, apply or disable policies, or delete sources are applied only to the selected 500 sources.

If you select sources of events, the following buttons become available:

• Save to CSV—you can use this button to export data of the selected event sources to a file named event-source-list.csv in UTF-8 encoding.
• Apply policy and Disable policy—you can use these buttons to enable or disable a monitoring policy for a source of events. When enabling a policy, you must select the policy from the drop-down list. When disabling a policy, you must select how long you want to disable the policy: temporarily or forever.

  If there is no policy for the selected event source, the Apply policy button is inactive. This button will also be inactive if sources from different tenants are selected, but the user has no available policies in the shared tenant.

  In some rare cases, the status of a disabled policy may change from gray to green a few seconds after it is disabled due to overlapping internal processes of KUMA. If this happens, you need to disable the monitoring policy again.

• Remove event source from the list—you can use this button to remove an event source from the table. The statistics on this source will also be removed. If a collector continues to receive data from the source, the event source will re-appear in the table but its old statistics will not be taken into account.
