Free disk space is less than 10% on ESXi volume

Hi,

I am monitoring ESXi servers with Zabbix. These ESXi servers are linked to the following templates:

• Template ICMP Ping
• Template SNMP OS ESXi
• Template Virt VMware
• Template Virt VMware Guest
• Template Virt VMware Hypervisor

There is a item called "Disk partitions: Used disk on VMFS 5 in blocks" which is of the type "SNMPv2 agent". Because there is no word Template in front of the name of the item I assume that this item did not come from any template. Is this correct?

There is also a trigger which fires when the Free Disk Space goes below 10% ({SERVER:hrStorageUsedBlocks[5].last(0)} / {SERVER:hrStorageSizeBlocks[5].last(0)} > 0.9
This trigger is fired but I don't know how to find out which volume is volume 5 on our ESXi servers.

How to find out which volume is running out of free space?

Spent the last week setting up Zabbix and I'm having the same issue. The Zabbix (2.2) dashboard is reporting the following:

HOST: VMHost1, ISSUE: Free disk space is less than 10% on volume 31
HOST: VMHost1, ISSUE: Free disk space is less than 10% on volume 34

The only servers in our environment configured to use SNMP monitoring are 5 VMware hosts. The vast majority of our windows/linux servers (including virtual servers) have Zabbix agents installed.

Our VM hosts are running ESXi 5.1. I imported "Template SNMP OS ESXi" from a repository on this site and assigned all 5 VM hosts to it. How can I identify what volume 31/34 is referring to in vSphere or CLI?

Thanks in advance!
