Ok - So I've installed the Machine Agent w/ JRE bundle on a number of servers and can now see the disk space used per drive. Here's a sample copy of the full path:
Application Infrastructure Performance|Default Web Site|Hardware Resources|Disks|c-|Space Available
How do I now create a Health Rule to monitor disk space regardless of the volume on all servers in that application? I went into the "Alert & Respond" section but can't find a metric to use by browsing. So instead I choose "Servers" and then specified this above metric path asking to flag a critical if space available was less than 999999999999999 (just a test number so that it would flag on pretty much ANY condition) but it didn't seem to do anything.
Any help would be greatly appreciated.
(Note: We do not own the advanced server monitoring, so just trying to use the included basic server monitoring with the machine agent to alert on low disk space on our servers)
