      Description

      Firstly I love the new UI pages ( ZK Status and Nodes ) . Thanks Jan Høydahl 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

      1. Let’s show Approximate Size in human readable form.  We can use RamUsageEstimator#humanReadableUnits to calculate it
      2. Show warning symbol when Ensemble is standalone
      3. 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.
      4. 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
