       pmdamemcache - memcache performance metrics domain agent (PMDA)

       This PMDA extracts performance data from memcached, a distributed memory caching daemon
       commonly used to improve web serving performance.  A farm of memcached processes over
       multiple servers can be utilised by a single web application, increasing the total
       available object cache size, and decreasing the database load associated with smaller
       cache sizes.  This system is described in detail at http://www.danga.com/memcached.

       Configure pmdamemcache to extract the values from set of hosts used in the memcache farm.
       These hosts can be listed in the $PCP_PMDAS_DIR/memcache/memcache.conf file, in the format
       (i.e.  Perl array) described at the top of pmdamemcache.pl.  A custom refresh rate can
       also be configured using this mechanism.

	       # cd $PCP_PMDAS_DIR/memcache
	       # [ edit memcache.conf ]

       Once this is setup, you can access the names and values for the memcache performance
       metrics by doing the following as root:

	       # cd $PCP_PMDAS_DIR/memcache
	       # ./Install

       If you want to undo the installation, do the following as root:

	       # cd $PCP_PMDAS_DIR/memcache
	       # ./Remove

       pmdamemcache is launched by pmcd(1) and should never be executed directly.  The Install
       and Remove scripts notify pmcd(1) when the agent is installed or removed.

	   configuration file listing monitored memcache instances

	   installation script for the pmdamemcache agent

	   undo installation script for the pmdamemcache agent

	   default log file for error messages from pmdamemcache

       pmcd(1) and memcached(1).
