Veeam VMware: Database Health Alarm

Veeam.Virt.Extensions.VMware.vCenterEvent.DatabaseHealthAlarm (UnitMonitor)

Knowledge Base article:

Summary

This monitor tracks the vCenter Server Database Health Alarm.

Causes

vCenter Server checks how much free space is left in a database every 15 minutes, and triggers the vCenter Server Database Health Alarm if any of the preconfigured thresholds is breached. If the database is 80% full, you will get a warning. If the database is 95% full, vCenter Server will shut down.

By default, this alarm is triggered by the following events:

vCenter Event

Alarm Status

Description

DBHealthStatusClearEvent

alarm_status(green)

Database health status changed from YELLOW to GREEN.

DBHealthStatusWarningEvent

alarm_status(yellow)

Database health status changed from GREEN to YELLOW (used: 82%, threshold: 80%).

DBHealthStatusErrorEvent

alarm_status(red)

Database health status changed from GREEN to RED (used: 97%, threshold: 95%).

Resolutions

If the vCenter Server Database Health Alarm is not GREEN, try increasing the storage space for the database and restarting the VMware vCenter Server service. Another option is to delete unnecessary data from the database.

If you do not want the vCenter Server to shut down when the database is 95% full, you can change the vCenter Server Database Health Alarm default action, or you can also change the default preconfigured thresholds. For more information on both actions, see this VMware KB article.
