Please follow the link in my first post. my problem is, i`ll add the command to the normal email notification command. but nagios xi use the old notification command, not the new one...
Being this is built into xi I assumes you would not want to re-invent the wheel...
That being said, the link in the Exchange does go through the step by step process, of setting this up, the difference is that you would have to enter the commands through the CCM -> Commands instead of creating the config definition.
