I am fairly new to OpenNMS. Currently I am in the process of creating a simplified dashboard for all the nodes that I have configured. I plan on monitoring the cpu utilization and the memory availability on all the nodes. To do this, I am using the REST Api of OpenNMS. For the cpu utilization, I am able to get the stats using the following url :
From https://wiki.opennms.org/wiki/ReST#Measurements_API, I was able to get the basic url as :
However, I can't seem to determine the url for getting the memory available on the various disk drives (C:\\,D:\\,etc...)
How do I get the memory utilization and other such performance metrics for a node?
