Added CPU Details #255

Closed Munzy closed 4 years ago

Munzy commented 5 years ago

I have long wanted a way to monitor steal time on my VMs. I currently use a lot of VMs on hosting providers such as Linode, Digital Ocean, et cetera. These providers sometimes over-allocate a node to the point of becoming a problem. One way to indicate this issue is CPU Steal climbing beyond a certain percentage.

The goal is to allow LibreNMS to track users, system, idle, io wait, and steal numbers so that we can make better decisions on how to improve performance or mitigate performance issues on a VM.

New applications should output json format with labeled fields.

Alright. I'll see how I want to refactor it.

rewritten to use same data via UCD MIB SNMP, which are usually transfered, also.
