The zabbix agent send incorrect utilization of cpu which twice less than output of top command:
On agent server:
[root@xxx]# top|grep Cpu %Cpu(s): 84.6 us, 8.3 sy, 0.0 ni, 5.5 id, 0.0 wa, 0.0 hi, 1.6 si, 0.0 st %Cpu(s): 82.8 us, 8.7 sy, 0.0 ni, 6.9 id, 0.0 wa, 0.0 hi, 1.6 si, 0.0 st %Cpu(s): 84.9 us, 9.4 sy, 0.0 ni, 4.0 id, 0.0 wa, 0.0 hi, 1.7 si, 0.0 st %Cpu(s): 82.7 us, 9.1 sy, 0.0 ni, 6.5 id, 0.0 wa, 0.0 hi, 1.7 si, 0.0 st %Cpu(s): 84.1 us, 8.1 sy, 0.0 ni, 6.0 id, 0.1 wa, 0.0 hi, 1.7 si, 0.0 st %Cpu(s): 84.9 us, 8.1 sy, 0.0 ni, 5.6 id, 0.0 wa, 0.0 hi, 1.4 si, 0.0 st %Cpu(s): 84.3 us, 7.9 sy, 0.0 ni, 6.2 id, 0.0 wa, 0.0 hi, 1.6 si, 0.0 st
At the same time on zabbix server:
[root@yyy bin]# zabbix_get -sxxx -p10050 -k system.cpu.util[] 49.139935 [root@yyy bin]# zabbix_get -sxxx -p10050 -k system.cpu.util[,user] 49.171261 [root@yyy bin]# zabbix_get -sxxx -p10050 -k system.cpu.util[,system] 4.926904
[root@yyy bin]# zabbix_get -sxxx -p10050 -k system.cpu.util[] 49.079076 [root@yyy bin]# zabbix_get -sxxx -p10050 -k system.cpu.util[,user] 49.082120 [root@yyy bin]# zabbix_get -sxxx -p10050 -k system.cpu.util[,system] 4.890176
And the same incorrect values for another server:
[root@xxx2 ~]# top|grep Cpu %Cpu(s): 96.6 us, 2.7 sy, 0.0 ni, 0.1 id, 0.0 wa, 0.0 hi, 0.6 si, 0.0 st %Cpu(s): 96.5 us, 2.8 sy, 0.0 ni, 0.2 id, 0.0 wa, 0.0 hi, 0.5 si, 0.0 st %Cpu(s): 96.3 us, 3.0 sy, 0.0 ni, 0.1 id, 0.0 wa, 0.0 hi, 0.6 si, 0.0 st %Cpu(s): 94.3 us, 4.6 sy, 0.0 ni, 0.3 id, 0.0 wa, 0.0 hi, 0.7 si, 0.0 st %Cpu(s): 96.2 us, 2.7 sy, 0.0 ni, 0.2 id, 0.0 wa, 0.0 hi, 1.0 si, 0.0 st %Cpu(s): 96.2 us, 2.7 sy, 0.0 ni, 0.4 id, 0.0 wa, 0.0 hi, 0.7 si, 0.0 st %Cpu(s): 95.2 us, 2.9 sy, 0.0 ni, 1.1 id, 0.0 wa, 0.0 hi, 0.7 si, 0.0 st %Cpu(s): 95.9 us, 2.7 sy, 0.0 ni, 0.7 id, 0.0 wa, 0.0 hi, 0.6 si, 0.0 st %Cpu(s): 96.4 us, 2.6 sy, 0.0 ni, 0.5 id, 0.0 wa, 0.0 hi, 0.5 si, 0.0 st
[root@ bin]# zabbix_get -sxxx2 -p10050 -k system.cpu.util[] 49.773875 [root@yyy bin]# zabbix_get -sxxx2 -p10050 -k system.cpu.util[,user] 49.734167 [root@yyy bin]# zabbix_get -sxxx2 -p10050 -k system.cpu.util[,system] 1.461466
[root@yyy bin]# zabbix_get -sxxx2 -p10050 -k system.cpu.util[] 49.714295 [root@yyy bin]# zabbix_get -sxxx2 -p10050 -k system.cpu.util[,user] 49.711913 [root@yyy bin]# zabbix_get -sxxx2 -p10050 -k system.cpu.util[,system] 1.471862
In attach the screenshot for cpu.util from this 2 servers.
I can reproduce this also in anouther servers, not only this 2
