Can triggers report the numerical differences

[RobC]

Hi

I have a couple of items being monitored - specifically the streaming replication 'value' from the master and slave servers.

The results I get back are in hex, formatted something like this :

0x30AF84DC2F (the Master)
0x30AF84C43B (the Slave)

The difference between the two is 17F4(hex) (6132 bytes).

I need a trigger that will diff the two results and produce an event based on the outcome (e.g. if the diff is greater than say 1Mb)

I've tried varients of :

{PGSQL:Master_RepLog} - {PGSQL:Slave_RepLog} > 1M

(where PGSQL:Master_RepLog is the monitoring key I'm getting results from)

but to no joy... any clues would be appreciated

Rob.

not sure about that, but you could make a shell script that would return this value, and create item/trigger of it.

Think you can use calculated items:
