disabling alerts

Hi,

I need to disable alerts on particular hosts. So I added '!' in from of the test but last night it alerted me. Please check my config and offer any help, thanks.

subpage MySQL MySQL group-only conn|!cpu|!disk|!memory|msgs 10.xxx.xxx.xxx 123.corp.local 10.xxx.xxx.xxx 345.corp.local 10.xxx.xxx.xxx 678 corp.local
