Where does Nagios XI put its SMTP mail logs?

[eloyd]

So I'm banging my head against this issue and can't find an answer:

Code: Select all

Where does Nagios XI put its mail logs when SMTP is chosen as the mail delivery mechanism?

I know I'm dense and I often forget to take out the trash, but I've grepped the entire file system and can't find what I'm looking for.

Hi,
If you have SMTP selected, but the Logging checkbox is unchecked like:

You will not have any output to a log file. However if you follow this document:
https://support.nagios.com/kb/article.php?id=820

you will be shown how to enable debug logging.

Then you can watch these files:

Code: Select all

/var/log/maillog
/usr/local/nagiosxi/tmp/phpmailer.log

Thanks

All these years, I've been thinking that Nagios has been logging SMTP traffic to...you know...syslog all along. Now when I need to go find something, it's not there and I discover this.

Thanks. I would strongly suggest that this be a checkable box in the config GUI rather than having to go edit class files which tend to get overridden during upgrades. It would have been sooooo much easier!

You can close this.

Hi Eric,

We'll close this out.
