Okay. I can a open a PR to minimally remove this functionality unless the 
commit needs to be completely reverted.

I apologize. It should've been my responsibility primarily.
I think I might be able to achieve the same graphs and live updates using 
`d3`, which I assume is compatible. Working on it right now.

Thanks! For now, we'll try to make a release without that page. We can add

I'm already working on a change to remove only the charts. Apparently, `d3` 
would work for us because it is BSD-lincensed.

This is referencing your addition in WebRuntimeMonitor. You can use this

"TASKMANAGER_ID_KEY".

Wouldn't it be better to return an InstanceNotFound message instead of a

Tried out your changes it everything worked without quirks. The initial 
look is a bit odd when the charts haven't loaded yet but this is nothing that 
should prevent us from merging the PR. I've also made a comment inline.

+1 for merging

Not sure about the null check. Could check for InstanceNotFound message 
instead.

The initial look is a bit weird, I agree. There is a potential fix, by 
fetching the usage upto the point when someone clicks on the `metrics` tab, 
however, that can be quite large if the cluster has been running for a long 
time. This would require storing the metrics history on the job manager, which 
will unnecessarily waste memory.

metrics only for one particular instance to minimize unnecessary traffic for a

@iampeter , thanks for the review. I've addressed all your comments.
I removed the `No such task ...` thing entirely. It doesn't have a use case 
anyways. We don't expect the user to break things on the server here. If the 
task manager doesn't exist, it is handled gracefully by the backend and an 
empty array is returned.

Although there's not much to review here. :') It's mostly a rearrangement
