      Description

      Steps to reproduce:

      1. add a server with more than 40 threads (20cores with hyperthreading)
      2. stress the CPU somewhat.
      3. see system.cpu.util[,user]
      4. compare to real stats on server
      5. see that system.cpu.util[,*] stats do not add up to 100% in total.

      I tried 3.0 and 4.0 version of agent with the same result.

      Other machines that have 40 or less threads work just fine with both centos 6.1 and 7.5 and zabbix agent 2.2 and 3.0 (latest for each distribution).

      Result:
      See screenshot...
