# Plugin to monitor execution time of PHP with access.log from apache server.

# Need to use apache module mod_log_config and have  set logformat like this:

# LogFormat "%h %l %u %T/%D %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" time_combined

#

# Min, Max and Avg are calculated on number of page, default 10. On high traffic site, increase this value and you get a better

# stat, on low traffic site keep small value, it's must be avg number of page every 5 minutes.

#

# Require read permissions for $LOG

#  (set in /etc/munin/plugin-conf.d/munin-node on debian)

# On busy servers you can change value type to COUNTER and set min to 0 to avoid minus peaks at logrotate
