Triggers not working like expected

[momiars]

I'm relatively new to zabbix so I'm sure I must be missing something. I'm trying to monitor a process I checked that the key works locally on the client using

 zabbix_agentd -t  proc.num[,,,ntpd]

this returns [u|2]

So when I made the trigger

 .[B]last([/B]0[B])[/B]}<2

however this does not seem to be working if I kill the process or have it running it reports as PROBLEM when I change it to CODE] .last(0)}>2[/CODE] it reports as OK even if the process is down. I have tried the following

 .[B]last([/B]0[B])[/B]}<=2

 .[B]last([/B]0[B])[/B]}<1

 .[B]last([/B]0[B])[/B]}=1

 .[B]last([/B]0[B])[/B]}=0

 .[B]last([/B]0[B])[/B]}>=1

 .[B]last([/B]0[B])[/B]}>=2

I suspect it may not have to do with the trigger at all and perhaps some miss configuration of the key?

Can you show the full expression, rather than just what you've tried for the trigger?

As an example, the full expression we use for monitoring the # of named processes (running as the 'named' user) is

{somehost.example.com:proc.num[named,named].last(0)}<1

Also, does querying the item like you've done still return [u|2] when you've killed the process?
