Detecting unexpected device behavior

Azure Cyclecloud Node QA

This project will qualify individual nodes before they join a cluster.

For failing nodes you may see something like this in the message queue:

Cyclecloud-NodeQA (NodeName:hpc-pg0-1/Hostname:ip-0A010A06/VMId:af4d08e9-1273-4bfc-babc-84a6a9e19c71) 
Cyclecloud-NodeQA ERROR: Device 0 measured 21.8 GB/s BW, expected 23 
Cyclecloud-NodeQA ERROR: Device 1 measured 21.8 GB/s BW, expected 23 
Cyclecloud-NodeQA ERROR: Device 2 measured 21.7 GB/s BW, expected 23 
Cyclecloud-NodeQA ERROR: Device 3 measured 21.7 GB/s BW, expected 23 
Cyclecloud-NodeQA ERROR: Device 4 measured 21.8 GB/s BW, expected 23 
Cyclecloud-NodeQA ERROR: Device 5 measured 21.8 GB/s BW, expected 23 
Cyclecloud-NodeQA ERROR: Device 6 measured 21.8 GB/s BW, expected 23 
Cyclecloud-NodeQA ERROR: Device 7 measured 21.8 GB/s BW, expected 23

The VM metadata will be written to a file on the node /tmp/NodeQA but will only be available for short amount of time because this project will delete failing nodes.

Manually started nodes will be removed. Nodes that are autoscaled will be replaced but manually added nodes will not.
