Nagios Support Forum

Greetings,

Migrated from Nagios core 3.0.3 to Nagios XI 2014R2.0 using the Nagios VM OVA deployment. Working on email notifications and noticed in the logs they are being reported, but never are delivered. I have changed the email settings to use Sendmail and have setup a relayhost in Procmail to relay off our internal email server so I can get better debug logs.

Looking at the /usr/local/nagios/var/nagios.log and noticed the following.

[1418911525] SERVICE NOTIFICATION: user1;da01;U01/app;WARNING;notify-service-by-email;/U01/app: 89%used(118625MB/133120MB) (>85%) : WARNING

Any assistance would be appreciated!

Thanks!

Well, notifications are getting sent from nagios. Lets check your maillog:

I did resolve the issue, it appears that mailx-12.4-7.el6.x86_64 installs the mailer as /usr/bin/Mail (upper case "M"), I created a soft link as /usr/bin/mail (mail with a lower case "m"). Resolved the issue, alerts flowing.

Thanks!

Great, We'll Go Ahead And Close This Thread. cAsE mAtTerS in *nix Thanks.
