Имя (Name)
pmdaredis - Redis performance metrics domain agent (PMDA)
Описание (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.

Окружение PCP (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).
