I need to monitor GPU statistics on a Windows machine.

I have found out that there are performance counters that can do it.

So I ran this:

C:\Users\admin>typeperf -q | find "GPU"
\GPU Local Adapter Memory(*)\Local Usage
\GPU Engine(*)\Utilization Percentage
\GPU Engine(*)\Running Time
\GPU Adapter Memory(*)\Shared Usage
\GPU Adapter Memory(*)\Dedicated Usage
\GPU Adapter Memory(*)\Total Committed
\GPU Process Memory(*)\Shared Usage
\GPU Process Memory(*)\Dedicated Usage
\GPU Process Memory(*)\Non Local Usage
\GPU Process Memory(*)\Local Usage
\GPU Process Memory(*)\Total Committed
\GPU Non Local Adapter Memory(*)\Non Local Usage

Now I query "\GPU Engine\Utilization Percentage" from CLI:

PS C:\Users\admin> Get-Counter -Counter "\GPU Engine(*)\Utilization Percentage"

As you can see, some processes are utilizing GPU which altogether gives me around 50%.

But if I query with zabbix_get I get this:

[maksimse@zabbix-server-node1 ~]$ zabbix_get -s <host> -k perf_counter["\GPU Engine(*)\Utilization Percentage"]
0.000000

Why? Is it a bug?
