       pmdanutcracker - NutCracker performance metrics domain agent (PMDA)


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


       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, do the following 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.

       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).
