duplicates ZBX-20356 Collecting perf_counter problem on Wi... Closed

 Description   

Steps to reproduce:

  1. Install and start agent 2 on a Windows server with line `HostMetadataItem=system.uname` in the agent configuration file.
  2. Create an autoregistration rule with the following:
    Condition: Host metadata contains Windows
    Operation: Link to templates: Windows by Zabbix agent active

Result:
The host will register with the server but all items using performance counters will not collect data. In the agent logs the following message shows up multiple times:

2021/09/23 07:05:23.360574 plugin 'WindowsPerfMon' collector failed: The handle is not a valid PDH object.

Expected:
I was able to get the items to start collecting data by restarting the agents on the hosts. I think the expected behavior should be that the items begin collecting data without requiring a restart of the agent on the monitored machines.

Thank you for contacting us.

I cannot reproduce the issue on Zabbix instance 5.4.4 with Windows Version 10.0.19042.1237 while using Zabbix agent 2 (x64) 5.4.4. All 13 'perf_counter_en' items work on the first boot up.

Try to open 'PerfMon.msc' console open on Windows system and try simulating auto registration again. If you have any Antivirus/hardening software, try to unload them.

Let us know the outcome.

Hello Aigars.

I removed an existing host and added a new host to the system and I could not reproduce the issue - all performance related items were working.

When I reported this issue it was a brand new server installation and the only host being monitored was the server itself. After I set up the auto registration rule I had four Windows hosts created and all four had problems with the performance counter items.

You can close this issue - I will reopen it if it happens again and I can reproduce it.

Thanks
