Network interface errors in last day

[ahowell]

Hi,

I'm trying to write a trigger that will alert on network interface errors in the last day. Any suggestions?

I've tried the following which doesn't seem to work

This is trigger against a LLD rule in 1.9.8

{Template_WEL_Linux:net.if.total[{#IFNAME},errors].last(0)} - {Template_WEL_Linux:net.if.total[{#IFNAME},errors].last(0,86400)} > 0

Think I just needed some brackets around the arthimetic. This seems to work

({Template_WEL_Linux:net.if.total[{#IFNAME},errors].last(0)}-{Template_WEL_Linux:net.if.total[{#IFNAME},errors].last(0,86400)})>0
