Performance of a server

NAME
pmdamemcache - memcache 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 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. FILES
$PCP_PMDAS_DIR/memcache/memcache.conf configuration file listing monitored memcache instances $PCP_PMDAS_DIR/memcache/Install installation script for the pmdamemcache agent $PCP_PMDAS_DIR/memcache/Remove undo installation script for the pmdamemcache agent $PCP_LOG_DIR/pmcd/memcache.log default log file for error messages from pmdamemcache SEE ALSO
