Using Nagios 3, I’m trying to send email notifications when servers get low on disk space. I’ve googled and read so many doc’s and tut’s on setting this up that my eyes are bleeding and still can not get Nagios to send out any emails. I’ve made the necessary entries to the contacts.cfg and contactgroups.cfg files and still get nothing. I can manually send myself an email from the command line with mailx so I know its working and the problem is with Nagios but for the life of me I can not find out where the problem is.
Not sure what information I need to include here, so if there’s a critical piece that anyone needs to help me troubleshoot this let me know and I’ll post it a.s.a.p.
Thanks in advance to anyone who can help point me in the right direction.
