A repository query that returns all disks (per monitored server) with less than 15% free space. The alert format is returned as follows: Key (server name), value (% free space).
Disk space values are collected from table PerformanceAnalysisDeviceLogicalDisk and the data is collected every 15 minutes by default.
The PDLD.Name NOT LIKE '\\?\Volume{%' in the query is used to filter out old mount points and system partitions from the result set. Additional drives may be excluded in the same manner.
This alert will display on the Windows: Disk Latency Dashboard Chart.
