%description
pl_mom is a suite of PlanetLab node monitoring tools.

swapmon is a swap monitoring daemon. Every 30 seconds, it checks
process memory usage. At 90% utilization, resets the slice that is
consuming the most physical memory. At 95% utilization, it reboots the
machine to avoid a crash.

bwmon is a cron job that monitors the average bandwidth usage of each
slice and enforces a daily byte limit for each slice.

pl_mop is a cron job that "fixes" various common problems with nodes
(dead services, ext3 corruption, zombie SSH sessions, etc.).
