[jira] [Updated] (SOLR-14305) Improve tooling for OPS and Support
personnel
[ https://issues.apache.org/jira/browse/SOLR-14305?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ishan Chattopadhyaya updated SOLR-14305:
----------------------------------------
Summary: Improve tooling for OPS and Support personnel (was: Improve tooling for OPS and Support personell)
> Improve tooling for OPS and Support personnel
> ---------------------------------------------
>
> Key: SOLR-14305
> URL: https://issues.apache.org/jira/browse/SOLR-14305
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: scripts and tools
> Reporter: Jan Høydahl
> Priority: Major
>
> Umbrella issue for tasks which will improve the lives of Operations and Support personell running large Solr clusters. The following description snippet is copy/paste from a comment by Shalin on another issue:
> There's plenty of information that is required for troubleshooting but is not available in clusterstatus or any other documented/public API. Sure there's the undocumented /admin/zookeeper which has a weird output format meant for I don't know who. But even that does not have a few things that I've found necessary to troubleshoot Solr.
> Here's a non-exhaustive list of things you need to troubleshoot Solr:
> # Length of overseer queues (available in overseerstatus API)
> # Contents of overseer queue (mildly useful, available in /admin/zookeeper)
> # Overseer election queue and current leader (former is available in /admin/zookeeper and latter in overseer status)
> # Cluster state (cluster status API)
> # Solr.xml (no API regardless of whether it is in ZK or filesystem)
> # Leader election queue and current leader for each shard (available in /admin/zookeeper)
> # Shard terms for each shard/replica (not available in any API)
> # Metrics/stats (metrics API)
> # Solr Logs (log API? unless it is rolled over)
> # GC logs (no API)
> Please link related tasks or create new sub tasks as necessary.
> Fixing SOLR-7796 would probably help a lot in the short term since there would be a well defined way to zip up info and send to support. But it won't hurt adding better APIs, small tools and new AdminUI panels for simplified live troubleshooting as well.
