# This plugin uses CURL to access the Drupal instance over HTTP. For most
# plugin modules, this could also work in CLI mode using Drush, and a Drush
# plugin implementation is a no-brainer. However, in most cases, this will be a
# lower performance option, because CLI code is not cached in APC, causing
# extra I/O load to fetch the files from disk everytime, whereas they will
# normally be cached in APC when using HTTP access.

# The timeout needs to be "not too short", because on
# system reboot, munin will often send probes before
# Apache is ready and, if they timeout, will not register
# the Munin plugins invoking this scripts for further
# probes, and it will have to be restarted manually.
#
# In addition, if you encounter "Connection refused" errors after system
# reboot, you may want to force a munin-node restart. In Ubuntu 10.10,
# for example, this can be done by adding:
#
#   @reboot /bin/sleep 60 ; /usr/sbin/restart munin-node
#
# in /etc/cron.d/munin to force a munin restart 1 minute after cron restart.
