[openstack-dev] [gnocchi] Running tests

[Andres Alvarez]

Hello everyone

I am having a hard time in understanding the correct way to run the tests
in Gnocchi. I have already read about tox and testr, but it seems I still
can't get to run the tests.

Would really appreciate if someone could explain the steps necessary to get
all tests running.

[openstack-dev] [gnocchi] Running Gnocchi API in specific interface

[Andres Alvarez]

Hello folks

The gnocchi-api command allows running the API server usign a spefic port:

usage: gnocchi-api [-h] [--port PORT] -- [passed options]

positional arguments:
  -- [passed options]   '--' is the separator of the arguments used to start
the WSGI server and the arguments passed to the WSGI
application.

optional arguments:
  -h, --helpshow this help message and exit
  --port PORT, -p PORT  TCP port to listen on (default: 8000)

I was wondering if it's possible as well to use a specific interface? (In
my case, I am working on a cloud dev environment, so I need 0.0.0.0)?

If not, would this be a welcomed change for a pull request?

Thanks

[openstack-dev] [telemetry][ceilometer] Devstack Telemetry development environment

[Andres Alvarez]

Hello all

I was wondering what is the correct way to setup a Devstack dev environment
with Ceilometer + Gnocchi setup?

Is the following the only thing needed to get started or is there something
else needed?:

enable_plugin ceilometer https://git.openstack.org/openstack/ceilometer


I noticed the "devstack/settings" file directory in the Ceilometer
repository. I am not sure if this should be copied and pasted into
local.conf

Would appeciate some help.

Cheers

Hi Julien

Thanks for your response. So does this mean that dispatchers will also be
deprecated (if not already deprecated) in favor of only using publishers?

[openstack-dev] [telemetry] [ceilometer] Difference between publishers and dispatchers?

[Andres Alvarez]

Hi everyone

I am a bit confused on what is the difference between dispatchers and
publishers in Ceilometer. The documentation explains a bit about publishers
in the pipeline, but it does not mention much (if anything) about
dispatchers.

Would appreciate if someone can shed some light on this.

Thanks.

[openstack-dev] [ceilometer]

[Andres Alvarez]

Hello everyone

I am trying to get acquainted with the Ceilometer code base. I was reading
through the Telemetry Admin Guide

regarding publishers and noticed that there are many deprecated publishers
such as *direct*, *kafka*, and *database*. Yet on the source code's master
branch

can still see some of these publishers there.

Is there a reason for this?

Sorry if it's a dumb question.

Wish you all a good day.
Andres
