    Description

      We are monitoring Windows servers with Zabbix agent. In some cases (not all) we see that the values collected by system.cpu.util are different from the Performance charts of the task manager and also when collecting the same value from the performance counters.

       

      Environment:

      • Zabbix agent: 5.0.17
      • Zabbix server and proxy: 5.0.21

       

      Steps to reproduce:

      1. monitor CPU using built in system.cpu.util
      2. monitor CPU using perf_counter
      3. look at performance charts directly on the server

       

      Result:

      Here are two screenshots of two different servers

      Server Monitored values Performance tab of task manager
      A    
      B    

       

       

      Expected:
      I would expect the values collected by system.cpu.util to be similar to the perf_counters and the Permformance tab of the taks manager. A little difference might be acceptable as the values might be collected at different times.
