proc.cpu.util is CPU intense

[hanspeter]

Hi,
I'm still on Zabbix 3.4 with zabbix-agent-3.4.15-1.el7.x86_64 being the running agent on the monitored linux nodes.

When I monitor certain processes with proc.cpu.util (two in this case, Interval 1min), the overall CPU load that the agent generates jumps from about 0.1-0.2% (observed with top), to 1.5-1.7%.
Is there a way to reduce this? Monitoring is supposed to be lightweight, but this introduces a lot of jitter to the system.

Thanks!
