Имя (Name)
pmdanutcracker - NutCracker performance metrics domain agent
(PMDA)
Описание (Description)
This PMDA extracts performance data from NutCracker (or
TwemProxy), a fast and lightweight proxy for memcached and Redis
protocol.
Установка (Installation)
Configure to export statistics via its stats interface (see
--stats-port option to the nutcracker server). The corresponding
configuration must be reflected in the
$PCP_PMDAS_DIR/nutcracker/nutcracker.conf file.
# cd $PCP_PMDAS_DIR/nutcracker
# [ edit nutcracker.conf ]
Once this is setup, you can access the names and values for the
nutcracker performance metrics by doing the following as root:
# cd $PCP_PMDAS_DIR/nutcracker
# ./Install
To uninstall, the following must be done as root:
# cd $PCP_PMDAS_DIR/nutcracker
# ./Remove
pmdanutcracker 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).
