Check process problem (content-gateway)

[rfuresz]

Hi Guys,

I try to check the content-gateway process working.
Item:
proc.num[,,,'content-gateway']
Trigger:
{hostnameroc.num[,,,'content-gateway'].last()}=0
I got warning sign about not working this process, but with zabbix_get:
zabbix_get -s x.x.x.x -p 10050 -k proc.num[,,,'content-gateway']
2

What mistake I made?

thanks a lot,
Robert

SOLVED: [not using ' sign in the trigger:
proc.num[,,,content-gateway].last()}=0
