Shalin Shekhar Mangar updated SOLR-9896:
----------------------------------------
Attachment: SOLR-9896.patch
Patch which instruments the following thread pools:
# UpdateShardHandler's updateExecutor and recoveryExecutor at the path
{{solr.http/updateShardHandler.threadPool.updateExecutor}} and
{{solr.http/updateShardHandler.threadPool.recoveryExecutor}}
# HttpShardHandler's httpShardExecutor at
{{solr.http/httpShardHandler.threadPool.httpShardExecutor}}
# CoreAdminHandler's parallelCoreAdminExecutor at
{{solr.node/QUERYHANDLER./admin/cores.threadPool.parallelCoreAdminExecutor}}
# CoreContainer's coreContainerWorkExecutor and coreLoadExecutor at
{{solr.node/threadPool.coreContainerWorkExecutor}} and
{{solr.node/coreLoadExecutor}}
There are still other thread pools in IndexFetcher and CDCR components which
aren't instrumented but this is a good start. We can add instrumentation if
people find them interesting.
