Reading the log

Development reference · View source

:log-open opens the log of the process that owns this workspace as a read-only [log] buffer, searchable, splittable, and scrollable as usual.

In mux mode that is the host’s host.log. No client-side trace is opened or merged.
:service-health names the owner role, active level, resolved path, and any logger failure.

Each record is one line: an RFC 3339 timestamp, the level, the owning role and PID, the abbreviated workspace ID, the subsystem, the message, and any structured key=value context.
