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