Windows CSV Performance counters become unsupported

[jeremyd]

I am seeing a weird issue with performance counters on a HyperV cluster

When I (or the cluster) moves disks to another member, zabbix starts notifying that the items are unsupported

This is from the zabbix server itself.

jeremy@Zabbix:/$ zabbix_get -s HYPERVHost -k perf_counter["\Cluster CSV Volume Manager(volume2)\IO Read/sec - Redirected"]
ZBX_NOTSUPPORTED: Cannot obtain performance information from collector.

However from a power shell removed into that HyperV host

[HYPERVHost]: PS C:\Windows\system32> get-counter -Counter "\Cluster CSV Volume Manager(volume2)\IO Read/sec - Redirected"

Timestamp                 CounterSamples
---------                 --------------
12/22/2016 8:51:58 AM     \\HYPERVHost\cluster csv volume manager(volume2)\io read/sec - redirected :
                          0

Restarting the zabbix-agent on the host fixes this

jeremy@Zabbix:/zabbixdirs$ zabbix_get -s HYPERVHost -k perf_counter["\Cluster CSV Volume Manager(volume2)\IO Read/sec - Redirected"]
0.000000

Moving the disk to another member causes this to become not supported again until I restart the zabbix agent.
