Structured logs includes a link to the trace if available. However, a trace can be big and you still may not know from exactly which point the log message was created.

The structured log knows its trace and span. We should craft the link so it opens the detail trace with the span details open.

Describe the solution you'd like

Improve the link to include the span in the URL so that span details for a log message open.
