Subject [jira] [Created] (DRILL-5821) In the Drill web UI, display configured direct, heap memory
Date Wed, 27 Sep 2017 01:52:00 GMT
Paul Rogers created DRILL-5821:

             Summary: In the Drill web UI, display configured direct, heap memory
                 Key: DRILL-5821
                 URL: https://issues.apache.org/jira/browse/DRILL-5821
             Project: Apache Drill
          Issue Type: Improvement
    Affects Versions: 1.11.0
            Reporter: Paul Rogers
            Assignee: Paul Rogers
             Fix For: 1.12.0

When diagnosing memory-related issues, the first question we always ask is, "how much memory
has Drill been given." This turns out to be rather tedious: we have to log onto the node running
Drill, track down the config value, and check the configured amount. Since there are multiple
possible config files, we have to figure out which was actually used.

An alternative is to do `ps aux | grep Drill` to look at the command line, but this also requires
access to the node itself.

As an easier route, just as we display encryption information on the web UI main page, display
the following:

Direct Memory: ## GB
Heap Memory: # GB
Cores: ##
