MongoDB
The MongoDB plugin allow you to monitor a number of metrics on the Mongo database on your server. If you have not installed MongoDB and you would like to install it go to https://docs.mongodb.com/manual/installation/ for instructions. If you can not find this plugin in the /usr/lib/fm-agent/plugins folder, then your version of the Agent is out of date and you should update it to gain access to this feature.
