Ishan Chattopadhyaya updated SOLR-6673:
---------------------------------------
Attachment: log4j.properties
MDC.patch
Here's a patch for this. The stamping is done from wherever the collection,
shard, core names become available first. There are many more places from where
this MDC based stamping could be done, this is just for a start and should
cover the important places.
Attached log4j.properties is from the location:
solr/core/src/test-files/log4j.properties
> MDC based logging of collection, shard etc.

> In cloud mode, the many log items don't contain the collection name, shard
> name, core name etc. Debugging becomes specially difficult when many
> collections/shards are hosted on the same node.
> The proposed solution adds MDC based stamping of collection, shard, core to
> the thread.
