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
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 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.
