--------------------------------------------
Summary: Implement an API to return Solr and GC logs
Key: SOLR-11958
URL: https://issues.apache.org/jira/browse/SOLR-11958
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: logging
Reporter: Shalin Shekhar Mangar
Fix For: master (8.0), 7.3
Solr shows the most recent log messages in the UI today. But it is kept in
memory and the number of events returned is limited. It is very useful to
retrieve the real log from servers during troubleshooting sessions. In most
places, without involving security issues, human intervention is required to
login, locate and download the log files which slows down the troubleshooting
process.
I propose to introduce a logging API (perhaps we just enhance the existing
/admin/logging handler) which can stream logs before/after/between given
timestamp(s), filter by level etc to help debug issues faster. Similar to Solr
logs, the same API can also output GC logs as well. We can choose to keep this
API disabled by default for security or keep it enabled but call it out in the
Upgrading section of CHANGES.txt
