Description

Problem 1 Currently, there's no way (AFAIK) to find all log messages associated with a particular request.

Problem 2 There's also no easy way for multi-tenant Solr setups to find all log messages associated with a particular customer/tenant.

Both of these problems would be more manageable if Solr could be configured to record an MDC tag based on a header, or some other user provided value.

This would allow admins to group together logs about a single request. If the same header value is repeated multiple times this functionality could also be used to group together arbitrary requests, such as those that come from a particular user, etc.
