    We can't put this and the remaining functions within the IF block since the localhost
operations are still valid. i.e. an authenticated client on a specific Drillbit can ping that
Drillbit for refresh of the metrics. Only shutdown function needs to be managed with the IF
block

>             Project: Apache Drill
>          Issue Type: Improvement
>          Components: Web Server
>    Affects Versions: 1.13.0
>            Reporter: Kunal Khatua
>            Assignee: Kunal Khatua
>            Priority: Major

>   Original Estimate: 168h
>  Remaining Estimate: 168h

> When fixing DRILL-6224, I noticed that the same information can be very useful to have
in the cluster view shown on a Drillbit's homepage. 
> The proposal is to show the following:
> # Heap Memory in use
> # Direct Memory (actively) in use - Since we're not able to get the total memory held
by Netty at the moment, but only what is currently allocated to running queries
> # Process CPU
> # Average (System) Load Factor 
> Information such as the port numbers don't help much during general cluster health, so
it might be worth removing this information if more real-estate is needed.
