 HA Proxy Logging on Lion
 -------------------------

 # To enable haproxy logging we need to change syslogd startup procedure to include its network listener.

 # Backup syslogd start up file
 sudo cp /System/Library/LaunchDaemons/com.apple.syslogd.plist   /System/Library/LaunchDaemons/com.apple.syslogd.plist.bakup


 # Convert binary file to xml to be human readable / editable
 sudo plutil -convert xml1 /System/Library/LaunchDaemons/com.apple.syslogd.plist

 # Edit /System/Library/LaunchDaemons/com.apple.syslogd.plist and add The following snippet under the sockets  node

 <key>NetworkListener</key>
 <dict>
 <key>SockServiceName</key>
 <string>syslog</string>
 <key>SockType</key>
 <string>dgram</string>
 </dict>

 # Should read like this now
 <key>Sockets</key>

	<key>AppleSystemLogger</key>
	<dict>
		<key>SockPathMode</key>
		<integer>438</integer>
		<key>SockPathName</key>

 # Save the file

 # Convert back to binary file
 sudo plutil -convert binary1 /System/Library/LaunchDaemons/com.apple.syslogd.plist

 # Restart syslogd
 launchctl unload /System/Library/LaunchDaemons/com.apple.syslogd.plist
 sudo launchctl load /System/Library/LaunchDaemons/com.apple.syslogd.plist

 # I added the following entry to /etc/syslog.conf
 local2.*						/var/log/haproxy.log

 # Include logging options in haproxy.cfg
 global
    log 127.0.0.1   local2 debug

 defaults
