Difference in Sum

[midlandmonkey]

Hello,
I'm fairly new to Zabbix, although i've been configuring items and triggers for the last few months in a hosted environment.
Essentially, I have a batch file which uses a windows version of grep, to search for a string lets say "test". This counts the amount of times it finds "test" and outputs a value.
This works, and Zabbix is giving me a nice result which increases throughout the day. The issue is, this is the sum.

What I need, is a a trigger when the value increases by X in the last Y minutes. My item gets the value every 30 seconds.

I could do:

• Difference between last and previous value > - though this is only the last 30 seconds. I want to monitor possible the last 5 minutes

Because my script only counts the "total" and not new occurrences, its making it a little difficult, but i cant really change my script.

Any help would be appreciated!

Store value as Delta

The change you could make from the Zabbix config side is to change the way that the item is stored. In the item configuration there is a combo box titled "Store value". If you change that to be "Delta (simple change)" it will then store whatever the difference is between each time it receives a value. Then you could easily set up a trigger for the item to go off whenever X (the received value) is greater than Y (the change value you define).

Brilliant Solved it in one. I knew there would be a simple way, but as usual it isnt until you know it, that it reveals itself to being simple.

This will help me immensely!

Thanks,
