Zabbix agent showing wrong value

[theLordOfYeast]

Hi,

I have a problem with monitoring Hyper-v server. I downloaded template from this website: http://www.poormans.network/2013/04/...or-zabbix.html. Almost all items work perfectly besides two: HyperV Virtual Switch B/s Received and HyperV Virtual Switch B/s Sent (data rate in bits per second). They always show value 0, even though server is working and sending and receiving data.

I've tried the same template on two different Hyper-v servers - it works on them, data rate value is different from 0 and constantly changing. So there may be a problem with this particular server. But the rest of items return right values, so I suppose it can't be connection or firewall issue.

My Zabbix version: 3.0.5.
Item keys: perf_counter[\Hyper-V Virtual Switch(*)\Bytes Received/sec]
perf_counter[\Hyper-V Virtual Switch(*)\Bytes Sent/sec]

I've tried restarting server, using different port and changing templates. I found nothing in the log file because from the Zabbix point of view there is no error - it just doesn't see any data.

If anyone has any idea about the reason of this problem, please share, it would be a great help.

Have you run perfmon on the server and seen what values it is showing? It is possible the NIC on that one server is named slightly different, compare running perfmon on both servers to see what is available, perfmon will only show what is actually available on that server at that time. If you can see it in perfmon and translate that over to a zabbix item it should work.
