NAME
       pmdabind2 - BIND performance metrics domain agent (PMDA)

DESCRIPTION
       This PMDA extracts performance data from BIND (Berkeley Internet Name
       Domain).  It enables collection of most of the statistics metrics from
       the Bind server version 9 or later, which includes:

       o overall memory statistics

       o overall per-query statistics (general queries, EDNS/truncated
         responses, Update/Notify/AXFR/IXFR messages)

       o overall error statistics (Rejected, SERVFAIL, Update/XFR failures
         ...)

       o overall statistics per transport protocol, EDNS and per version of IP
         protocol

       o resolver statistics (successes, errors, round-trip times in several
         ranges)

       o detailed per-socket statistics with respect to the transport protocol
         and IP version including errors

       o detailed per-file-descriptor statistics including errors

       The PMDA performs per-second collection of the whole data set (148
       metrics on the test environment) with modest requirements (2% CPU usage
       on Intel i7-4700MQ @2.4 GHz, cca 30 MB RAM).

       If more than 1 requests/sec is performed, the memoized values are used
       so that the statistics interface of the Bind server does not get
       overloaded.

INSTALLATION
       Configure BIND to export XML statistics via its REST interface.  This
       requires BIND configuration to enable statistics exporting locally (at
       least).

           statistics-channels {
               inet 127.0.0.1 port 8080 allow { 127.0.0.1; };
           }
           options { zone-statistics yes; }
           # ./Install

       The hostname (localhost), port (8080 above) and other configuration
       information must be specified in both the BIND configuration file as
       well as the $PCP_PMDAS_DIR/bind2/bind2.conf file.

           # cd $PCP_PMDAS_DIR/bind2
           # [ edit bind2.conf ]
             host=localhost.localdomain:8080

       Once this is setup, you can access the names and values for the bind2
       performance metrics by doing the following as root:

           # cd $PCP_PMDAS_DIR/bind2
           # ./Install

       To uninstall, the following must be done as root:

           # cd $PCP_PMDAS_DIR/bind2
           # ./Remove

       pmdabind2 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/bind2/bind2.conf
           mandatory configuration file listing monitored bind2 instances

       $PCP_PMDAS_DIR/bind2/Install
           installation script for the pmdabind2 agent

       $PCP_PMDAS_DIR/bind2/Remove
           undo installation script for the pmdabind2 agent

       $PCP_LOG_DIR/pmcd/bind2.log
           default log file for error messages from pmdabind2

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).
