Varun Thacker created SOLR-12692:
------------------------------------
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
