------------------------------------

             Summary: Add hints/warnings for the ZK Status Admin UI
                 Key: SOLR-12692
                 URL: https://issues.apache.org/jira/browse/SOLR-12692
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: Admin UI
            Reporter: Varun Thacker
         Attachments: zk_ensemble.png

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
