Nagios Support Forum

Can someone direct me to where I can reset communication info for Nagios 3.4.4 Core. We recently performed a major network upgrade where subnet schemes were changed. I was able to correct all IFCONFIG and ROUTE info. Our Nagios system is online and monitoring correctly, just not getting the notification for outages. Notifications are done by email to our cell carrier (i.e. [email protected]) which comes through as a text. Just not sure where to look for email server settings. Thanks!

Take a look at /var/log/maillog, are you seeing any information about them sending there?

Thanks for the suggestion. I know this is the issue as the mail server address changed but don't know where to edit it.

Log shows this:

dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to 10.48.1.2[10.48.1.2]:25: No route to host)

Is 10.48.1.2 your old mail server IP? I would check either your notify-host-by-email and notify-service-by-email (or whatever is assigned to your contacts), or one of your sendmail / postfix mail configuration files.

You could try running this to see where the IP is on your system -
