rsyslog from Heroku drain creates empty log files
- by Jeff Lee
I'm sending logs from my Heroku app to an rsyslog server, but the resulting log files seem to come up empty. The rsyslog configuration for receiving remote messages is as follows:
$template RemoteDailyLog,"/var/log/remote/%hostname%/%$year%/%$month%/%$day%.log"
:fromhost-ip, !isequal, "127.0.0.1" -?RemoteDailyLog
& ~
My complete rsyslog configuration is available in this paste.
This configuration appears to create the directories correctly. I see the Heroku app's logging hostname (of the form "d.xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx") appear in /var/log on the rsyslog host, which implies that log messages are successfully making it to the logging daemon, but the resulting logfiles are zero-size.
I'm guessing the issue is with rsyslog, rather than Heroku, but I'm not sure where to look next.
