Meet The Reaper

“The Reaper” keeps logs that were only intended to be human parsable.
Eventually, we needed to parse those logs automatically.

Notes:

The reaper is a script we use at pair to monitor and then renice or terminate processes that exceed certain resource usage boundaries.

It builds really long log lines like this:

Sat Apr 17 13:31:33 EDT 2004 :: (Long-running process) NICE 20: USER ehdonhon, CMD '/usr/local/bin/perl ./score.pl -b -t 0.5'/'perl'

Sat Apr 17 13:32:03 EDT 2004 :: (Long-running runaway) KILL -9: PID 13378, USER ehdonhon, CMD '/usr/local/bin/perl ./score.pl -b -t 0.5'/'perl'

Sat Apr 17 13:49:34 EDT 2004 :: (Common mail command) NICE 20: USER mattr, CMD '/bin/sh -c preline /usr/local/bin/procmail'/'sh'
