https://github.com/dtaht/bqlmon/commit/ace44b55e2e521af88ba9927bf30fe615024073d#diff-aacbd6867cca49695bfe76ad2bcd45d1R407
Now, that we are in control of the output format. I would output
something that is easier to parse for netperf-wrapper, e.g. some json
compliant string (it is future extendable and easy to parse for Toke).
Besides the output format, I like you patch to bqlmon.
Perhaps Toke have an opinion on the output formatting from bqlmon?
