Does Zabbix have the capability to identify top 10 process usage on a system

[pmurtey]

Hi All,
Does Zabbix out of the box have the capability to select a host, and have it identify what the top cpu using processes are that are running on that system?
TIA

We are looking to have the alert when cpu utilization go above 90% to generate the alert currently in place, but add to the (email) alert the top 5 processes running at the time of the alert. Can anyone share how we can go about doing this?

Hi!
You can create a bash script, for example, ps_cpu.sh like this:

#!/usr/bin/bash
ps -eo pcpu,pid,user,args | sort -k 1 -r | head -5 | awk '
BEGIN { ORS = ""; print " [ "}
{ printf "%s{\"user\": \"%s\", \"pid\": \"%s\", \"cpu\": \"%s\"}",
separator, $1, $2, $3
separator = ", "
}
END { print " ] " }';

This bash script converts ps output to JSON.

Then add the line to the agent's config and restart the agent:

UserParameter=high.cpu.topprocess, /etc/zabbix/ps_cpu.sh

Create a new item for the host =high.cpu.topprocess and a new trigger. Set dependency from your CPU 90% trigger there.

Hi Vladimir, We will definitely give this a try. Just to be clear, the script itself and the change to the config, has to be performed individually on each system? Correct?

Yes, it should be created for each host on the agent side.
