PMDAREDIS(1)

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

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, do the following 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).
