Background

To prevent the logfiles for DEIMOS processes from getting overly large, the newlog procedure runs periodically to "roll" the logfile. The newlog process will move current logfile foo to foo.0, and the old foo.0 will become foo.1, etc., until a maximum number of old versions (typically 5) is exceeded; the oldest file will then be removed. The newlog process can optionally compress the old logfiles.

Invocation

The newlog script runs as root and is invoked as a cron job. The crontab entry is as follows:

	0 * * * * /local/ucolick/root/sbin/newlog -f /local/ucolick/root/etc/newlog.conf

Configuration

The newlog.conf file controls which files are compresed, when they are compressed, how many versions are retained, etc. The files lives at

	/local/ucolick/root/etc/newlog.conf

To edit the file requires root access. The file header documents the contents of the file.
