How to setup a trigger on first value and on value change with zabbix
Trigger Expression:
{MyTemplate:MyItem.count(#2)}<2 or {MyTemplate:MyItem.diff()=1}
Calculate the Prints Monthly Average on Zabbix
Assuming that “pagecount” is the global counter item of our printer we can create a calculated item with the following expression:
max(pagecount,2592000)-min(pagecount,2592000)
where 2592000 is the number of seconds (30 days, i.e 60sec x 60min x 24hours x 30days) of our interval to get the minimum and the maximum number detected.
