Skip jobstats metric if they don't exist #60

Closed roclark closed 7 years ago

roclark commented 7 years ago

In case a particular jobstats metric isn't located on a node, skip over it instead of trying to parse a value, yielding unexpected results.

Hmm, out of curiosity, what were the unexpected values?

@joehandzik it would default to parsing the job_id for the specified block. So if, for some reason, one job had write_bytes but another job didn't, you would get expected results for the first, but they would be compared against job_id for the other which would obviously be confusing.
