# with TTL 300 seconds, add a cron jobs like this to
# collect 5 minutes of data:
#
# 0,5,10,15,20,25,30,35,40,45,50,55 * * * * ufr.sh

# and something like the below to clean out the log files every 4 days

# Clean up UFR logs  -- HP Unix version
# 0 3 * * * nice find /var/log/ufr/*   -type d -a -mtime 4 -exec rm -rf {} \; 2>/dev/null

# Clean up UFR logs  -- Linux version (uses GNU find)
# 0 3 * * * nice find /var/log/ufr/*/* -maxdepth 0 -mtime +5 -exec rm -r {} \; >/dev/null 2>/dev/null
