NAME

       pmdanutcracker - NutCracker performance metrics domain agent (PMDA)

DESCRIPTION

       This PMDA extracts performance data from NutCracker (or TwemProxy), a fast and lightweight
       proxy for memcached and Redis protocol.

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.

FILES

       $PCP_PMDAS_DIR/nutcracker/nutcracker.conf
           mandatory configuration file listing monitored memcache or Redis instances

       $PCP_PMDAS_DIR/nutcracker/Install
           installation script for the pmdanutcracker agent

       $PCP_PMDAS_DIR/nutcracker/Remove
           undo installation script for the pmdanutcracker agent

       $PCP_LOG_DIR/pmcd/nutcracker.log
           default log file for error messages from pmdanutcracker

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).
