PMDAREDIS(1)             General Commands Manual            PMDAREDIS(1)

NAME         top

       pmdaredis - Redis performance metrics domain agent (PMDA)

DESCRIPTION         top

       This PMDA extracts performance data from sending the INFO command
       to a Redis (redis.io) server, which includes:

       • General information about the Redis server

       • Client connections

       • Memory consumption

       • Persistence statistics

       • Replication statistics

       • CPU consumption statistics

       • Redis command statistics

       • Redis Cluster statistics

       • Database related statistics

       The hostname (localhost), port (6379 by default) and other
       configuration information must be specified in the
       $PCP_PMDAS_DIR/redis/redis.conf file.

           # cd $PCP_PMDAS_DIR/redis
           # [ edit redis.conf ]
             host=localhost.localdomain:6379

       To uninstall, the following must be done as root:

           # cd $PCP_PMDAS_DIR/redis
           # ./Remove

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

           # cd $PCP_PMDAS_DIR/redis
           # ./Install

       To uninstall, the following must be done as root:

           # cd $PCP_PMDAS_DIR/redis
           # ./Remove

       pmdaredis 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         top

       $PCP_PMDAS_DIR/redis/redis.conf
           mandatory configuration file listing monitored redis
           instances

       $PCP_PMDAS_DIR/redis/Install
           installation script for the pmdaredis agent

       $PCP_PMDAS_DIR/redis/Remove
           undo installation script for the pmdaredis agent

       $PCP_LOG_DIR/pmcd/redis.log

PCP ENVIRONMENT         top

       Environment variables with the prefix PCP_ are used to
       parameterize the file and directory names used by PCP. On each
       installation, the file /etc/pcp.conf contains the local values
       for these variables.  The $PCP_CONF variable may be used to
       specify an alternative configuration file, as described in
       pcp.conf(5).
