Help with creating a value from a log file

[HaveDill]

Basically this log file im trying to parse will spit out a line containing the string

ReceivedNaks: 192.168.xxx.xxx=239 (or some other value.)

I'm trying to configure zabbix to find this line, get the value 239, and set up triggers based on what the value is at.

Even better would be if i could have it trigger off that value, and when looking at the alert if it spit out what IP address was in front as well.

Here's what the output looks like just looking for that line:



Any help is appreciated

Anyone ever implement something like this? Or at least some examples other than the documentations so i can get a better idea of how to figure it out??
