Proactive system health alerts

The following section describes how the HEALTHCHECK component shows system health events, resulting from proactive system health alerts in the IBM Storage Scale system.

The new system health component, HEALTHCHECK, has been introduced to improve the experience of users with Call Home enabled, by providing a more direct support from IBM® to those users without any detours.

The HEALTHCHECK component monitors the call home scheduled uploads, which are sent to the IBM server and analyzed by the IBM health check service. In case there are any security issues or misconfiguration, alerts are generated by the health check service. The HEALTHCHECK component monitors the proactive system health alerts.

Note: For a detailed description about the received health events, check the output of the mmhealth event show command. All these information updates are retrieved from the IBM support server once a day.

The given procedure is followed to generate system alerts:

  1. Perform a scheduled call home upload to the IBM health check service.
  2. Analyze the new data.
  3. Raise system health alerts.
  4. Download data from IBM using the monitoring cycle of the HEALTHCHECK component.

This procedure could take more than 24 hours to complete. Therefore, if the root cause of the alert is fixed, then the event related to that alert is not immediately reflected in the mmhealth command output. In order to get rid of the event immediately, use the following command:

mmhealth event resolve <event_name>
Note: Ensure that in this case, the issue described by this health event is resolved. Otherwise, it would reappear in the mmhealth command output.

If a user intentionally does not want to solve the reported issue and no longer wants to be warned, then use the following command to disable this particular check:

mmhealth event hide <event_name>

To unhide such a hidden event, issue the following command:

mmhealth event unhide <event_name>

Only the HEALTHCHECK events, which are received from the IBM health check service, can be hidden. These event names start with hc_.
