# Copy this to your node's config file (default: plugin-conf.d/munin-node):
#  [php_sessions]
#  user root
#  env.sessiondir /var/lib/php/session
#
# Modify env.sessiondir to match your system's setting. This should be fine
# on most systems.
#
# Changes

# 2011-02-13, subpardaemon: add env.sessiondir, make sure find uses
#                           the given path (it hadn't before)
# 2011-01-01, guilloux : find commands & plugin conf improvements

# 2008-10-10, schweizer: forked from munin_squid_efficiency
