Nagios Monitoring MongoDB

Nagios itself does not provide a service to monitor MongoDB and needs to install plugins

has been written by the Great God plugin Nagios_plugin-mongodb

Address Https://github.com/mzupan/nagios-plugin-mongodb

Record how to use the

First switch to the directory where the script is located on the monitor machine

Cd/usr/local/nagios/libexec

git clone git://github.com/mzupan/nagios-plugin-mongodb.git

CD Nagios-plugin-mongodb

PIP Isntall Requirements

This installs the script, mainly the check_mongodb.py

The script is written in Python and requires the installation of the Pymongo library in Python, and the previous requirements has Pymongo so it's installed.

Next up is the play configuration file

Edit Command.cfg File

Vim/usr/local/nagios/etc/objects/command.cfg

In the end, add the following specific instructions what meaning can be switched to the script file under execution./check_mongodb.py--help to view

Then edit the configuration file of your monitored machine

Basically, it's all configured.

The most important step is to check that the configuration file is correct

/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfg

If correct, restart Nagios and Nrpe, and remember to monitor the firewall to open port 27017.

The above is done directly by executing a script to manipulate MongoDB

You can also use the Nrpe to monitor

Change the configuration file for the monitoring machine.

Define a service to check Mongodb in the Remvoe machinedefine service{        use                             generic-service        Host _name                       vm_test        service_description             check_mongodb_connect        check_command                   check_nrpe!check_ Mongodb_connect        }

Modify the nrep.cfg file on the monitored machine

10.0. 0.99 27017 4 2 -u username-p password

Restart Nrpe and Nagios

Using the second method of Nrpe is successful, the first is not successful and does not know why.
