Email Notifications

[Andreas Ericsson]

Two things I'd like you to think about when next posting to a
public mailing list:
1. Don't remove the mailing-list from the list of recipients.
   Doing so means the mailing list archives will not contain the answer
   to your problem, and those of us who answer it on the list will be
   forced to answer it over and over and over again.
2. Don't top-post. It makes it excessively hard to understand what
   you're replying to, and it makes those list archives pretty much
   useless since people can't read the questions before the answers.

I noticed. That's a really wild shot in the dark. I take it you're not
overly familiar with unix systems?

If you're not, and noone else in your organization can help you, I'd
really recommend getting professional help setting up your Nagios system.

Altinity is UK-based and do Nagios-related consultancy work. They can
probably help you get up and running in a very short time.

op5 is Sweden-based (and I work there, so shameless plug here we go),
but can do installations remotely with a little help from an on-site
technician. We'll also do on-site, ofcourse, but travelling costs are
sometimes prohibitive.

http://www.nagios.org/support/servicepartners/ has a (much) more
comprehensive list.

No, you can do that using templates. Reading the nagios documentation
before you get cracking would be well spent time.
