I am using zabbix 3.4 and more than 150+ hosts and 15k+ items are running. I want to see the top 5 process lists on my mail while trigger cpu load is too high. what is the possible to way to solve it? Another thing, I don't want to see the top process list in history items, as too many hosts it consumes so many load on zabbix server. Is there any way to solve ?
