NAME

       pmdaredis - Redis performance metrics domain agent (PMDA)

DESCRIPTION

       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.

PCP ENVIRONMENT

       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).
