Hi Andres,
Ceilometer has deprecated collector from Pike, so dispatchers will be no
longer used in the future. Data should be pushed from publisher to storage
backend(e.g. Gnocchi) and/or other outer system. Some dispatchers
were deprecated because there are corresponding developed publisher, for
example, file dispatcher to file publisher. Of course, If you still want to
use previous version, you could use dispatcher behind collector.

Best wishes,
Hanxi Liu

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?

Publishers are configured into the pipeline to indicate where to push
samples data (e.g. to Gnocchi).
One of the publisher is notifier:// which sends the samples to the (now
deprecated) ceilometer-collector process.

Ceilometer collector stores data into other system via a dispatcher
mechanism (e.g. to Gnocchi). It's now deprecated as it's just, with
current architecture, a unnecessary step: publishers can do the job
directly.

[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.
