Why my trigger not working?

[jix]

Hi All

I have trigger like this to detect user downloads



if difference between maximum and avg of graph during 300 sec more that 6M then alarm

but with this graph my trigger not works i dont know why?



i also try to replace max fun with last (0) but didnt works

any one know where is my problem? or maybe zabbix bug?

Did you try to play around period of time?
Like :
....max(300) -
....avg(3600)

In this case you will compare the huge traffic spike in last 5 minutes with the typical traffic on this port in last one hour.

When you compare MAX and AVG for the same period it cannot be as big different as you hope.

"6 M" is not numeric at all.
