nova logs don't include line numbers anymore

[Joe Gordon]

Nova logs (Devstack early Havana) do not include line numbers.

Line numbers are very useful when working with debug output.

Additionally nova-api logs don't include the context anymore, which contained the request-id which was useful for associating logs with a specific API request.

[Joe Gordon (jogo)]

Looks like the issue is devstack is overwriting the default log format to something much less useful.

[Andrew Laski (alaski)]

https://review.openstack.org/#/c/24032/ changed logging so that the default log_format is used, rather than the much more informative context and debug logging formats.

we'll still need to switch from default to legacy formatter to get the "old-style" logs

    Import latest log module from oslo

    Deprecates log_format in favor of the formatting options used by the
    context aware formatter, such as logging_default_format_string.

    Changes the default logging formatter back to a colorful and context
    aware formatter. The default was inadvertently changed in the great
    oslo sync at the start of Havana, this returns it to what was in at the
    end of Grizzly.

    Adds support for lazy instantiation of the logger.

The request ID is still missing in devstack logs, making it difficult to troubleshoot issues in the gate test runs.

[Andrew Laski (alaski)]

Andrea, can you link an example where they're missing? In one of my devstack runs from last night http://logs.openstack.org/36729/2/check/gate-tempest-devstack-vm-full/31359/logs/screen-n-api.txt.gz you can see the request ids by searching for "req-".
