PROGRAM:
NAME
pmdamemcache - memcached performance metrics domain agent (PMDA)
DESCRIPTION
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.
INSTALLATION
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
To uninstall, 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.
Use pmdamemcache online using onworks.net services
