NAME         top

       pmdamongodb - MongoDB database metrics

DESCRIPTION         top

       pmdamongodb is a Performance Co-Pilot (PCP) Performance Metrics
       Domain Agent (PMDA) which extracts live performance data from a
       running MongoDB database server.

CONFIGURATION         top

       Firstly, pmdamongodb requires installation of the pymongo support
       packages - a general purpose Python module for querying MongoDB.

       Next, pmdamongodb reads an optional ini-style configuration file:

              $PCP_PMDAS_DIR/mongodb/mongodb.conf

       This file currently allows for two sections, one for configuring
       the MongoDB socket connection, the other for authentication.

       [connection]

       host (localhost)
              Connect to the MongoDB socket on the given hostname.

       port (27017)
              Connect to the MongoDB socket on the given port.

       [authentication]

       username (empty)
              Username to connect to the database.

       password (empty)
              Password to connect to the database.

INSTALLATION         top

       To install, the following must be done as root:

           # cd $PCP_PMDAS_DIR/mongodb
           # ./Install

       To uninstall, the following must be done as root:

           # cd $PCP_PMDAS_DIR/mongodb
           # ./Remove

       pmdamongodb 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         top

       $PCP_PMDAS_DIR/mongodb/mongodb.conf
            configuration file for the pmdamongodb agent

       $PCP_PMDAS_DIR/mongodb/Install
            installation script for the pmdamongodb agent

       $PCP_PMDAS_DIR/mongodb/Remove
            undo installation script for the pmdamongodb agent

       $PCP_LOG_DIR/pmcd/mongodb.log
            default log file for messages from the pmdamongodb agent

       Note that the usual/default value for $PCP_PMDAS_DIR is
       /var/lib/pcp/pmdas and the default for $PCP_LOG_DIR is
       /var/log/pcp but these settings are platform dependent.

PCP ENVIRONMENT         top

       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).
