> Project: Solr
> Issue Type: Improvement

> 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
