Description:

swatchdog.pl started out as swatch, the "simple watchdog" for activity
monitoring log files produced by UNIX's syslog facility. It has since
been evolving into a utility that can monitor just about any type of
log. The name has been changed to satisfy a request made by the old
Swiss watch company.

The Swatchdog utility monitors system log files, filters out unwanted data
and takes specified actions (i.e., sending email, executing a script,
etc.) based upon what it finds in the log files.

Install the swatchdog package if you need a program that will monitor log
files and alert you in certain situations.
