PMDAREDIS(1) General Commands Manual PMDAREDIS(1)
pmdaredis - Redis performance metrics domain agent (PMDA)
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_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
default log file for error messages from pmdaredis
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).
PCPIntro(1) and pmcd(1).
