devstack: GNOCCHI_USE_MOD_WSGI no longer work by default

[Mehdi Abaakouk]

Hi,

In the devstack plugin GNOCCHI_USE_MOD_WSGI no longer work by default, devstack statup fail because it doesn't found /var/log/$APACHE_NAME/gnocchi.log and /var/log/$APACHE_NAME/gnocchi-access.log

Set GNOCCHI_SERVICE_PORT workaround the problem.

This is because "apache-gnocchi.template" can't have the CustomLog and ErrorLog.

Cheers,

Presumably the most direct fix here is to tail a different log when port is not set? (in start_gnocchi)

The only problem with that is that the name of the generic default log file is probably not the same across distros.

I haven't seen this because I always run with USE_SCREEN False (and so does the gate, usually) and tail_log is a noop then.

    Tail the correct apache log files in devstack

    When port is not set, we tail the default logs, which
    will be quite noisy. In the future there will likely be a
    devstack tool that helps make this less noisy.
