Parse node_info.json from OpsCenter Diagnostics Report

Implement a new script which makes the node_info.json data readable.

I used this very crude one liner as a start, but we could really do with prefixing with the node IP / name:

for line in $(cut -d : -f1 node_info.json | grep "\".*\"" | sed -e "s/^ *\"//" -e "s/\"//" | sort -u | grep -v "^[1-2]"); do grep $line node_info.json ;done

I used these very simple python commands to get some particular output as an example. I think in this case python might be quite simple?

import json
data = json.loads(open('node_info.json').read())
for node in data:
    print data[node]['node_ip'],'\t',data[node]['agent_jvm_version']
