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