Disk Space Low (Script Poll)

Microsoft.FASTSearch.MP.Monitor.RTSIndexer.DiskSpaceScript (UnitMonitor)

Monitoring of free disk space for the 'indexDir' path configured in rtsplatformrc.xml (using script).

Knowledge Base article:

Summary

There are two different indexer disk space monitors. One monitor checks the 'FAST Search Indexer/Disk low state' performance counter that is reported by the indexer, while the other monitor uses a script to monitor free disk space for the 'indexDir' path configured in the file rtsplatformrc.xml that is located in the \etc folder of your FAST Search Server 2010 for SharePoint installation directory. .

The script version of the monitor has a warning level when there is less than 20% free disk space, and a critical level for when there is less than 10% free disk space. The 'Disk low state' performance counter is controlled by the configuration entry 'diskspaceMBWarning' in the configuration file rtsearchrc.xml (typical path: <FAST Search Server 2010 for SharePoint installation directory>\etc\config_data\RTSearch\webcluster\rtsearchrc.xml).

Causes

The system can run out of disk space for several reasons:
