There already quite a lot of blog posts out there which describe how to add performance counters to zabbix. In fact – its not that hard – the tricky thing is, to have one template which gets performance counters from systems wich have different languages installed.

In this case it’s a good idea to use the index of a counter. Indexes of all performance counters can be obtained from teh registry.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ Windows NT\CurrentVersion\Perflib
In this path there should be a key named “009” (would be englisch, “007” german) or similar, which contains all the key-value pairs.
The easiest way is to copy everything to an editor and look up the keys you need.

I tried to verify the counter ids by using them with “typeperf” – eg: typeperf \234(_Total)\202 but most times the result was:
Error: No valid counters.
If i used the names instead of the keys everything worked fine.

Atm I still don’t know what the reason for this error is, but, if you try it with  zabbix_get everything works fine.
zabbix_get -s server-01 -k “perf_counter[\234(_Total)\202]”
0.000000
