Chapter 5. Configuring Red Hat OpenStack Platform director Operator for Service Telemetry Framework
To collect metrics, events, or both, and to send them to the Service Telemetry Framework (STF) storage domain, you must configure the Red Hat OpenStack Platform (RHOSP) overcloud to enable data collection and transport.
STF can support both single and multiple clouds. The default configuration in RHOSP and STF set up for a single cloud installation.
- For a single RHOSP overcloud deployment using director Operator with default configuration, see Section 5.1, “Deploying Red Hat OpenStack Platform overcloud for Service Telemetry Framework using director Operator”.
5.1. Deploying Red Hat OpenStack Platform overcloud for Service Telemetry Framework using director Operator
When you deploy the Red Hat OpenStack Platform (RHOSP) overcloud deployment using director Operator, you must configure the data collectors and the data transport for Service Telemetry Framework (STF).
Prerequisites
- You are familiar with deploying and managing RHOSP with the RHOSP director Operator.
Procedure
- Section 4.1.1, “Getting CA certificate from Service Telemetry Framework for overcloud configuration”
- Retrieving the AMQ Interconnect route address
- Creating the base configuration for director Operator for STF
- Configuring the STF connection for the overcloud
- Deploying the overcloud for director operator
Additional resources
- For more information about deploying an OpenStack cloud using director Operator, see https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/17.1/html/deploying_an_overcloud_in_a_red_hat_openshift_container_platform_cluster_with_director_operator/index
- To collect data through AMQ Interconnect, see the amqp1 plug-in.
5.1.1. Getting CA certificate from Service Telemetry Framework for overcloud configuration
To connect your Red Hat OpenStack Platform (RHOSP) overcloud to Service Telemetry Framework (STF), retrieve the CA certificate of AMQ Interconnect that runs within STF and use the certificate in RHOSP configuration.
Procedure
View a list of available certificates in STF:
$ oc get secrets
Retrieve and note the content of the
default-interconnect-selfsigned
Secret:$ oc get secret/default-interconnect-selfsigned -o jsonpath='{.data.ca\.crt}' | base64 -d
5.1.2. Retrieving the AMQ Interconnect route address
When you configure the Red Hat OpenStack Platform (RHOSP) overcloud for Service Telemetry Framework (STF), you must provide the AMQ Interconnect route address in the STF connection file.
Procedure
- Log in to your Red Hat OpenShift Container Platform environment where STF is hosted.
Change to the
service-telemetry
project:$ oc project service-telemetry
Retrieve the AMQ Interconnect route address:
$ oc get routes -ogo-template='{{ range .items }}{{printf "%s\n" .spec.host }}{{ end }}' | grep "\-5671" default-interconnect-5671-service-telemetry.apps.infra.watch
5.1.3. Creating the base configuration for director Operator for STF
Edit the heat-env-config-deploy
ConfigMap to add the base Service Telemetry Framework (STF) configuration to the overcloud nodes.
Procedure
Log in to the Red Hat OpenShift Container Platform environment where RHOSP director Operator is deployed and change to the project that hosts your RHOSP deployment:
$ oc project openstack
Open the
heat-env-config-deploy
ConfigMap
CR for editing:$ oc edit heat-env-config-deploy
Add the
enable-stf.yaml
configuration to theheat-env-config-deploy
ConfigMap, save your edits and close the file:enable-stf.yaml

5.1.4. Configuring the STF connection for director Operator for the overcloud
Edit the heat-env-config-deploy
ConfigMap to create a connection from Red Hat OpenStack Platform (RHOSP) to Service Telemetry Framework.
Procedure
Log in to the Red Hat OpenShift Container Platform environment where RHOSP director Operator is deployed and change to the project that hosts your RHOSP deployment:
$ oc project openstack
Open the
heat-env-config-deploy
ConfigMap for editing:$ oc edit configmap heat-env-config-deploy
Add your
stf-connectors.yaml
configuration to theheat-env-config-deploy

The
resource_registry
configuration directly loads the collectd service because you do not include thecollectd-write-qdr.yaml
environment file for multiple cloud deployments. -
Replace the
host
sub-parameter ofMetricsQdrConnectors
with the value that you retrieved in Section 4.1.3, “Retrieving the AMQ Interconnect route address”. -
Replace the
<password_from_stf>
portion of thesaslPassword
sub-parameter ofMetricsQdrConnectors
with the value you retrieved in Section 4.1.2, “Retrieving the AMQ Interconnect password”. -
Replace the
caCertFileContent
parameter with the contents retrieved in Section 4.1.1, “Getting CA certificate from Service Telemetry Framework for overcloud configuration”. -
Set
topic
value ofCeilometerQdrMetricsConfig.topic
to define the topic for Ceilometer metrics. The value is a unique topic identifier for the cloud such ascloud1-metering
. -
Set
CollectdAmqpInstances
sub-parameter to define the topic for collectd metrics. The section name is a unique topic identifier for the cloud such ascloud1-telemetry
. -
Set
CollectdSensubilityResultsChannel
