Host Partition Storage Free Space Alert Problem

thtech

We have Virtualization Manager running in our environment and i'm having a strange issue with it. One of the alerts that comes up is in regard to Host partition storage free space. It states that if the local ESXi host partition falls below 20% free space, it will throw the alert. Great! I like that plan, however, it isn't working properly. Here is a readout from one of the hosts it's throwing the alert on. Any thoughts?

~ # df -hFilesystem   Size   Used Available Use% Mounted onVMFS-5       2.0T 984.0M      2.0T   0% /vmfs/volumes/ESXi_LUN14VMFS-5       2.0T 307.1G      1.7T  15% /vmfs/volumes/ESXi_LUN04VMFS-5     131.8G 971.0M    130.8G   1% /vmfs/volumes/ServerName_localVMFS-5       2.4T   1.8T    651.7G  74% /vmfs/volumes/ESXi_LUN15VMFS-5       2.0T 905.0G      1.1T  44% /vmfs/volumes/ESXi_LUN02VMFS-5       2.0T   1.3T    672.5G  67% /vmfs/volumes/ESXi_LUN12VMFS-5       2.0T   1.4T    591.7G  71% /vmfs/volumes/ESXi_LUN03VMFS-5       2.0T   1.4T    658.6G  68% /vmfs/volumes/ESXi_LUN01VMFS-5       2.5T   2.2T    373.0G  86% /vmfs/volumes/ESXi_LUN05VMFS-5       2.0T 405.1G      1.6T  20% /vmfs/volumes/ESXi_LUN13VMFS-5       2.0T   1.4T    657.1G  68% /vmfs/volumes/ESXi_LUN11vfat         4.0G  31.5M      4.0G   1% /vmfs/volumes/GUID1vfat       249.7M 142.3M    107.5M  57% /vmfs/volumes/GUID2vfat       249.7M 155.6M     94.1M  62% /vmfs/volumes/GUID3vfat       285.8M 183.4M    102.4M  64% /vmfs/volumes/GUID4

Now, as you can see, one of the LUN's is over 80% but that isn't a local host partition, the GUID1-4 and ServerName_local directories are the local storage.

Am I just viewing/interpreting this incorrectly or is something not reporting properly?

Any help is greatly appreciated!

The out of the box alert doesn't distinguish between local and shared shared storage. The scope of the search is

host.vol.freeSpacePercentage:[* TO 20]

If you click on the alert name, you can see the list of volumes that triggered the alert in the 'Least free space' column.

If you want to restrict the search (i.e., evaluate the alert) for certain volumes only, you can edit the Alert and change the search to something like

host.vol.freeSpacePercentage:[* TO 20]  host.vol.mountPoint:*LUN*

to restrict to volumes containing the word LUN
