Description Yurii Prokulevych 2016-09-26 10:56:40 UTC
Description of problem:
-----------------------
By default telemetry components(aodh/ceilometer) ain't installed by default on the undercloud.

This has to be well documented since CloudForms is using events processed by ceilometer.

Also, if telemetry is not installed/configured on undercloud, all the remaining services(nova/neutron/...) have to be configured not to emit notifications, until there is another consumer setup.


Version-Release number of selected component (if applicable):
-------------------------------------------------------------
instack-undercloud-5.0.0-0.20160907134010.649dc3f.el7ost.noarch

How reproducible:
-----------------
100%

Steps to Reproduce:
1. Install the undercloud.
2. Check telemetry related services ain't installed and running.

Comment 1 Marek Aufart 2016-10-18 11:06:46 UTC
Thanks for reporting this BZ. I can confirm that CloudForms uses Ceilometer on both Undercloud and Overcloud.

Are steps to enable Ceilometer manually available already?

Comment 2 Pradeep Kilambi 2016-10-18 14:54:40 UTC
@Marek:

Yes, before you run undercloud install set enable_telemetry = true in undercloud.conf.

Comment 3 Dan Macpherson 2017-09-20 04:50:34 UTC
Checking my backlog and found this bug. The description for "enable_telemetry" should be updated to include the default:

https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/10/html/director_installation_and_usage/chap-installing_the_undercloud#sect-Configuring_the_Director

enable_telemetry
    Defines whether to install OpenStack Telemetry (ceilometer, aodh) services in the undercloud. The default value is false, which disables telemetry on the undercloud. 

@Yurii, was this what you were after?

Comment 4 Yurii Prokulevych 2017-09-20 10:51:18 UTC
Partially, also I'd like to emphasize the impact if telemetry services are disabled.

Adding Julien cause he can has another pov.

Comment 5 Julien Danjou 2017-09-20 13:34:10 UTC
The biggest direct impact for customers is CloudForms not going to work correctly with telemetry disabled. I don't know if we want to talk about CloudForms in OSP documentation?

I imagine the current doc is enough otherwise.

Comment 6 Dan Macpherson 2017-09-21 01:57:33 UTC
It should be okay for just a casual mention. I'm very much in favor of pointing out the links between out products, so I'll add a reference to it.
