Greg Harris commented on SOLR-12692:
------------------------------------
Additional feature request would be if you could say do a click for a 'cons'
command which will show latencies and packets rcvd/sent on all connections.
This can be useful when determining if that max latency is an outlier or a
significant problem or packet communication on a connection. You could also do
ones for 'crst' (Connection reset of stats), 'srst' (Server reset of stats).
Possibly might add 'dump' for connection ids and attached ephemeral nodes, but
perhaps getting farther out there. I think the most important one here might
just be 'cons'

> Firstly I love the new UI pages ( ZK Status and Nodes ) . Thanks [~janhoy]
> for all the great work!
> I setup a 3 node ZK ensemble to play around with the UI and attaching the
> screenshot for reference.
>
> Here are a few suggestions I had
> # Let’s show Approximate Size in human readable form. We can use
> RamUsageEstimator#humanReadableUnits to calculate it
> # Show warning symbol when Ensemble is standalone
> # If maxSessionTimeout < Solr's ZK_CLIENT_TIMEOUT then ZK will only honor
> up-to the maxSessionTimeout value for the Solr->ZK connection. We could mark
> that as a warning.
> # If maxClientCnxns < live_nodes show this as a red? Each solr node connects
> to all zk nodes so if the number of nodes in the cluster is high one should
> also be increasing maxClientCnxns
