Log Rotation & OpenGroupware

OpenGroupware Legacy logs to numerous files in the directory /var/log/opengroupware; OpenGroupware Coils logs to the file /var/log/coils.log.  Managing these log files is an important part of service administrations - bad things happen if the system's /var/log fills up.  Rotating these files can be accomplished using the excellent logrotate facility provided by your LINUX distribution. logrotate reads all the files present in the /etc/logrotate.d directory - each service that requires log rotation can simply create configuration file for itself.  The recommended log rotation configurations for OpenGroupare Legacy and OpenGroupware Coils are as follows:

/var/log/opengroupware/*.log {
    copytruncate
    rotate 5
    daily
    size 10M
    missingok
    notifempty
    sharedscripts
    compress
}
The file /etc/logrotate.d/ogo for rotating OpenGroupware Legacy log files.

/var/log/coils.log {
    copytruncate
    rotate 5
    daily
    size 10M
    missingok
    notifempty
    sharedscripts
    compress
}
The file /etc/logrotate.d/coils for rotating OpenGroupware Coils log files.

You can adjust the "rotate" parameter to change how many log files you want to keep.  The setting of "rotate 5" and "daily" means the log rotator will keep 5 days worth of logs.  The most important option is "copytruncate" - this instructs the log rotator to make a copy of the current log file and then truncate the existing log file rather than moving the file and having a new file created, this allows the OpenGroupware services to continue to use the same file-handle for logging during [and after] the log rotation operation.
