If you’re a bit slow on the uptake, like me … this might help.

Basic logging to Loggly is simple enough –

References : https://www.loggly.com/docs/rsyslog-tls-configuration/ gets you to add in an omfwd action and a template with auth details in …

However, when you also want to mix in sending Apache logs to loggly, and at the same time want to suppress sending some lines ….. life becomes a bit harder.

Here’s what worked for me anyway… replace MAGIC_AUTH_TOKEN_HERE with your loggly auth details.

Place this in /etc/rsyslog.d/loggly.conf.

# Setup disk assisted queues
$WorkDirectory /var/spool/rsyslog # where to place spool files
$ActionQueueFileName fwdRule1     # unique name prefix for spool files
$ActionQueueMaxDiskSpace 1g       # 1gb space limit (use as much as possible)
$ActionQueueSaveOnShutdown on     # save messages to disk on shutdown
$ActionQueueType LinkedList       # run asynchronously
$ActionResumeRetryCount -1        # infinite retries if host is down
