The amount of system resources our monitoring agent uses on your system depends on the amount of server monitoring the agent has to do. If you have many roles assigned to your server, it will be a bit more busy then with fewer roles.

Here is an example of the running zabbix processes on one of our web servers:

[09-03-11 13:50:09] [root@xyz.com]
