Hello!

If my mind and logic working properly, then for triggers like "Zabbix server: Excessive" formula must be:

min(/Zabbix server health/rcache.buffer.pused,10m)>{$ZABBIX.SERVER.UTIL.MAX:"*"} 

In this case trigger fires only if item value is over {$ZABBIX.SERVER.UTIL.MAX:"*"} for last 10 min.

However in current state formula is:

max(/Zabbix server health/rcache.buffer.pused,10m)>{$ZABBIX.SERVER.UTIL.MAX:"*"}  

which like

last(/Zabbix server health/rcache.buffer.pused)>{$ZABBIX.SERVER.UTIL.MAX:"*"}  

Correct me if I'm wrong.
