=head1 FAQ

=head2 Q: Do I need to enable a logging plugin?

=head2 A: No.

When zero logging plugins are configured, logs are directed to STDERR. This
is the 'default' logging and logs are piped to multilog and stored in
log/main/current.

When more than zero logging plugins are enabled, builtin logging is disabled
and logs are sent to every logging plugin configured in config/plugins.


=head2 Q: How do I watch the logs?

=head2 A: Here's a few examples:

The default log files can be watched in real time lik this:

 tail -F ~smtpd/log/main/current

To convert the tai timestamps to human readable date time:

 tail -F ~smtpd/log/main/current | tai64nlocal

To exclude the dates entirely, use this command:

 tail -F ~smtpd/smtpd/log/main/current | cut -d' ' -f2-3


=head2 Q: How do I get alerts when qpsmtpd has a problem?

=head2 A: Send logs with levels below LOGERROR to syslog.

This can be done by adding the following lines to config/plugins:

  logging/syslog loglevel LOGERROR
  logging/warn LOGINFO

The warn logging plugin replicates the builtin logging, directing log messages to STDERR. The syslog plugin directs errors to syslog where standard monitoring tools can pick them up and act on them.

With these settings, errors will still get sent to STDERR as well.
