Re: Ambari Metrics Collector failing...

2017-09-07 Thread Simon Elliston Ball
Correct, it’s not critical. Metrics can help a bit with debugging things like 
node hotspots in Metron and in HDP generally, but it’s certainly not required 
to run.

I wouldn't consider it a show stopper myself, happy to be persuaded
otherwise.  I'm not even 100% sure it's related to Metron.  I just put it

Ambari Metrics Collector failing...

2017-09-06 Thread Laurens Vets
In preparation of 0.4.1-rc, I'm trying to install the current github 
master and I'm running into an issue with Ambari-metrics-collector. 
"Metrics Collector" seems to start, but immediately turns red again 
Ambari and stops.


Any idea what might be going on or where I can start troubleshooting 
this?
