Dave, TJ:
DIAG_MAIN was running slowly if it was asking for averages from h1nds0. I could not see any issues with h1nds0 with regards to cpu, memory or syslogs, but we rebooted it anyways and DIAG_MAIN sped back up. h1nds0 had been running since 1st May 2017.
This sped the exec time from ~7sec to ~0.2sec. I have rarely seen it this fast and I had to slightly change two of the tests to handle this. I also cleaned up a few of the tests and old tests while I was in there.
Edit: Forgot to attach the 5day trend of the exec time for future reference.
