------------------------------------------
Summary: Log responses for HTTP requests
Key: MESOS-3878
URL: https://issues.apache.org/jira/browse/MESOS-3878
Project: Mesos
Issue Type: Task
Components: libprocess
Reporter: Alexander Rukletsov
When an HTTP request comes in, we log it twice: in the libprocess using
{{VLOG}} and in Mesos route handlers using {{LOG(INFO)}} (see MESOS-2519).
However, we do not log the response, neither a successful one, nor even an
error.
In order to simplify debugging, I suggest we at least add symmetric logging for
*all* responses at the libprocess level using the same logging level as it is
used now for incoming requests. We may want to additionally log messages for
error responses (e.g. {{BadRequest}}, {{Conflict}} in Mesos with {{LOG(ERROR)}}
level, providing additional information like time took to process the request.
