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

       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.

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).
