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.
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?
@Marek: Yes, before you run undercloud install set enable_telemetry = true in undercloud.conf.
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?
Partially, also I'd like to emphasize the impact if telemetry services are disabled. Adding Julien cause he can has another pov.
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.
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.
Yep, this has been implemented: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/13/html/director_installation_and_usage/installing-the-undercloud#director-configuration-parameters
