haproxy

Aggregate logs from haproxy, a “reliable, high Performance TCP/HTTP load balancer,” including HTTP requests and errors.

Direct logging

haproxy supports remote syslog natively, so it can log directly to Papertrail. Edit haproxy.cfg and add a new global log configuration option like this, as well as log-send-hostname:

log logsN.papertrailapp.com:XXXXX local0
log-send-hostname

where logsN and XXXXX are the name and port number shown under log destinations.

Second, add log global to each server’s configuration stanza to indicate that it should use the aforementioned configuration.

haproxy supports up to 2 concurrent log configuration outputs.

Define syslog tag and/or hostname (optional)

Syslog messages include a program name (“tag”) and sender identifier (“hostname”). With the configuration above, haproxy will use default values of haproxy and the system hostname. These are typically fine.

Changing the tag is typically only necessary if you run multiple haproxy instances on the same system. Use different tag values to tell their logs apart.

Changing the hostname is rarely needed, since the system hostname is usually the best identification.

To change them, use the log-tag or log-send-hostname options.

Change logging verbosity (optional)

Optionally append a minimum severity from among the set:

log logsN.papertrailapp.com:XXXXX local0 warning

where logsN and XXXXX are the name and port number shown under log destinations.

Alternatives: local log file or system syslog

If you do not want to have haproxy log directly to Papertrail, you can use one of these two methods instead:

have haproxy log to a standalone text log file and transmit that to Papertrail. See Configuring centralized logging from text log files in Unix with remote_syslog2.
have haproxy log to the system’s syslog daemon and use that to transmit to Papertrail. See Configuring remote syslog from Unix/Linux and BSD/macOS.
