Comment 13 for bug 1519537

Don't get me wrong. I am all for diagnostics options, both passive and active. I am just not buying the need to have it exposed thru neutron REST API.

Speaking of active diagnostics, we have some limited thing for that called neutron-debug: http://docs.openstack.org/cli-reference/content/neutron-debug_commands.html

To validate configuration correctness, we also have neutron-sanity-check tool, but it's not designed for on-going operation monitoring.

I believe we can base new diagnostics tools and reports on neutron-debug (active) and oslo.reports (passive).

Note that I sent oslo.reports integration patch for review, and we will be able to base more reports leveraging the feature: https://review.openstack.org/#/c/250487/

So, let's work on defining the list of needed tools/diagnostics info/reports, and let's see which tooling we use for that.
