Summary

The operational database is running out of free space. Sufficient free space is needed to ensure that monitoring can continue uninterrupted. By default this monitor changes into a warning state of there is less than 40% available free space, and an error state if there is less than 20% available free space.

It is not recommended to change these thresholds, as 40% free space is generally required for a healthy operational database.

Causes

A large increase in the amount of data saved to the operational database can be caused by:

  • New agents added to the Management Group

  • New Management Packs imported

  • Changes to existing management pack rules or monitors

  • An operational condition in the environment that is causing more than the typical amount of data (e.g. more alerts)

Resolutions

Increase the amount of free space by growing the database file. You can also change the grooming settings to store data for a shorter period of time.
