Logger::Syslog is a Logger replacement that logs to syslog. It is almost drop-in with a few caveats. You can add Logger::Syslog to your Rails production environment to aggregate logs between multiple machines.
NOTE! You can only set the Logger::Syslog program name and facility when you initialize Logger::Syslog for the first time. This is a limitation of the way Logger::Syslog uses syslog (and in some ways, a limitation of the way syslog(3) works). Attempts to change Logger::Syslog’s program name or facility after the first initialization will be ignored.
This particular Logger::Syslog improves the original by correctly mapping Rails log severities to the Syslog counterparts. It also adds the ability to select a syslog facility other than “user.”
Version 1.6.7 takes a formatter as logger does and uses call to format the message.
config.gem 'syslog-logger'
gem 'syslog-logger'
(Only this environment, since you probably only want to enable it for Production, and not Test or Development.)
RAILS_DEFAULT_LOGGER = Logger::Syslog.new
By default, Logger::Syslog uses the program name ‘rails’ and the facility ‘user’, but this can be changed via the arguments to Logger::Syslog.new:
RAILS_DEFAULT_LOGGER = Logger::Syslog.new('mygreatapp', Syslog::LOG_LOCAL7)
Add the following lines:
!rails *.* /var/log/production.log
Or, in Mac OS X:
local7.* /var/log/production.log
Then touch /var/log/production.log and signal syslogd with a HUP (killall -HUP syslogd, on FreeBSD and OS X).
Add the following line:
/var/log/production.log 640 7 * @T00 Z
This creates a log file that is rotated every day at midnight, gzip’d, then kept for 7 days. Consult newsyslog.conf(5) for more details.
A basic setup:
destination rails_log { file("/var/log/production.log"); }; filter f_rails { program("rails.*"); }; log { source(src); filter(f_rails); destination(rails_log); };
A more advanced setup with formatting, etc:
destination rails { file("/var/log/rails_apps" owner("rails") group("rails") perm(0664) template("$DATE $HOST $PROGRAM [$LEVEL] $MSGONLY\n") template_escape(no) ); };
filter f_rails { (program("railsappone") or program("railsapptwo")) and not match("SQL ") and not match("SELECT") and not match("INSERT INTO") and not match("UPDATE"); };
log { source(src); filter(f_rails); destination(rails); };
Now restart your Rails app. Your production logs should now be showing up in /var/log/production.log. If you have mulitple machines, you can log them all to a central machine with remote syslog logging for analysis. Consult your syslogd(8) manpage for further details.
