Procedure

1. Log in to the undercloud host as the stack user.

2. Create a configuration file called enable-stf.yaml in the /home/stack directory.

   Important

   Setting EventPipelinePublishers and PipelinePublishers to empty lists results in no event or metric data passing to RHOSP telemetry components, such as Gnocchi or Panko. If you need to send data to additional pipelines, the Ceilometer polling interval of 30 seconds, that you specify in ExtraConfig, might overwhelm the RHOSP telemetry components. You must increase the interval to a larger value, such as 300, which results in less telemetry resolution in STF.

Procedure

1. Log in to the undercloud host as the stack user.
2. Create a configuration file called stf-connectors.yaml in the /home/stack directory.

3. In the stf-connectors.yaml file, configure the MetricsQdrConnectors address to connect the AMQ Interconnect on the overcloud to the STF deployment. You configure the topic addresses for Ceilometer and collectd in this file to match the defaults in STF. For more information about customizing topics and cloud configuration, see Section 4.4, “Configuring multiple clouds”.

   • The resource_registry configuration directly loads the collectd service because you do not include the collectd-write-qdr.yaml environment file for multiple cloud deployments.
   • Replace the host parameter with the value that you retrieved in Section 4.1.2, “Retrieving the AMQ Interconnect route address”.
   • Replace the caCertFileContent parameter with the contents retrieved in Section 4.1.1, “Getting CA certificate from Service Telemetry Framework for overcloud configuration”.
   • Replace the host sub-parameter of MetricsQdrConnectors with the value that you retrieved in Section 4.1.2, “Retrieving the AMQ Interconnect route address”.
   • Set topic value of CeilometerQdrEventsConfig to define the topic for Ceilometer events. The value is a unique topic idenifier for the cloud such as cloud1-event.
   • Set topic value of CeilometerQdrMetricsConfig.topic to define the topic for Ceilometer metrics. The value is a unique topic identifier for the cloud such as cloud1-metering.
   • Set CollectdAmqpInstances sub-paramter to define the topic for collectd events. The section name is a unique topic identifier for the cloud such as cloud1-notify.
   • Set CollectdAmqpInstances sub-parameter to define the topic for collectd metrics. The section name is a unique topic identifier for the cloud such as cloud1-telemetry.

Procedure

1. Log in to the undercloud host as the stack user.

2. Source the stackrc undercloud credentials file:

   $ source ~/stackrc

   Copy to Clipboard Toggle word wrap

3. Add your data collection and AMQ Interconnect environment files to the stack with your other environment files and deploy the overcloud:

   (undercloud)$ openstack overcloud deploy --templates \
    -e [your environment files] \
    -e /usr/share/openstack-tripleo-heat-templates/environments/metrics/ceilometer-write-qdr.yaml \
    -e /usr/share/openstack-tripleo-heat-templates/environments/metrics/qdr-edge-only.yaml \
    -e /home/stack/enable-stf.yaml \
    -e /home/stack/stf-connectors.yaml

   Copy to Clipboard Toggle word wrap
   • Include the ceilometer-write-qdr.yaml file to ensure that Ceilometer telemetry and events are sent to STF.
   • Include the qdr-edge-only.yaml file to ensure that the message bus is enabled and connected to STF message bus routers.
   • Include the enable-stf.yaml environment file to ensure that the defaults are configured correctly.
   • Include the stf-connectors.yaml environment file to define the connection to STF.

Procedure

1. Log in to an overcloud node, for example, controller-0.

2. Ensure that the metrics_qdr and collection agent containers are running on the node:

   $ sudo docker container inspect --format '{{.State.Status}}' metrics_qdr collectd ceilometer_agent_notification ceilometer_agent_central
   running
   running

   There are four connections:

   • Outbound connection to STF
   • Inbound connection from ceilometer
   • Inbound connection from collectd

   • Inbound connection from our qdstat client

     The outbound STF connection is provided to the MetricsQdrConnectors host parameter and is the route for the STF storage domain. The other hosts are internal network addresses of the client connections to this AMQ Interconnect.

5. To ensure that messages are delivered, list the links, and view the _edge address in the deliv column for delivery of messages:

3. Save the modifications.

4. Verify that the Operator deleted the Smart Gateways. This can take several minutes while the Operators reconcile the changes:

   $ oc get smartgateways

   Copy to Clipboard Toggle word wrap

Procedure

1. Create a new environment file, for example, hostnames.yaml.

2. Set the CloudDomain parameter in the environment file, as shown in the following example:

   hostnames.yaml

   parameter_defaults:
       CloudDomain: newyork-west-04
       CephStorageHostnameFormat: 'ceph-%index%'
       ObjectStorageHostnameFormat: 'swift-%index%'
       ComputeHostnameFormat: 'compute-%index%'

   Copy to Clipboard Toggle word wrap

3. Add the new environment file to your deployment.

Procedure

1. Log in to the undercloud host as the stack user.
2. Create a configuration file called stf-connectors.yaml in the /home/stack directory.

3. In the stf-connectors.yaml file, configure the MetricsQdrConnectors address to connect to the AMQ Interconnect on the overcloud deployment. Configure the CeilometerQdrEventsConfig, CeilometerQdrMetricsConfig, and CollectdAmqpInstances topic values to match the AMQP address that you want for this cloud deployment.

   stf-connectors.yaml

   resource_registry:
     OS::TripleO::Services::Collectd: /usr/share/openstack-tripleo-heat-templates/deployment/metrics/collectd-container-puppet.yaml

   • The resource_registry configuration directly loads the collectd service because you do not include the collectd-write-qdr.yaml environment file for multiple cloud deployments.
   • Replace the host parameter with the value that you retrieved in Section 4.1.2, “Retrieving the AMQ Interconnect route address”.
   • Replace the caCertFileContent parameter with the contents retrieved in Section 4.1.1, “Getting CA certificate from Service Telemetry Framework for overcloud configuration”.
   • Replace the host sub-parameter of MetricsQdrConnectors with the value that you retrieved in Section 4.1.2, “Retrieving the AMQ Interconnect route address”.
   • Set topic value of CeilometerQdrEventsConfig to define the topic for Ceilometer events. The value is a unique topic idenifier for the cloud such as cloud1-event.
   • Set topic value of CeilometerQdrMetricsConfig.topic to define the topic for Ceilometer metrics. The value is a unique topic identifier for the cloud such as cloud1-metering.
   • Set CollectdAmqpInstances sub-paramter to define the topic for collectd events. The section name is a unique topic identifier for the cloud such as cloud1-notify.

   • Set CollectdAmqpInstances sub-parameter to define the topic for collectd metrics. The section name is a unique topic identifier for the cloud such as cloud1-telemetry.

     Note

     When you define the topics for collectd and Ceilometer, the value you provide is transposed into the full topic that the Smart Gateway client uses to listen for messages.

     Ceilometer topic values are transposed into the topic address anycast/ceilometer/<TOPIC>.sample and collectd topic values are transposed into the topic address collectd/<TOPIC>.

     For an example of a cloud configuration in the ServiceTelemetry object referring to the full topic address, see the section called “The clouds parameter”.

4. Ensure that the naming convention in the stf-connectors.yaml file aligns with the spec.bridge.amqpUrl field in the Smart Gateway configuration. For example, configure the CeilometerQdrEventsConfig.topic field to a value of cloud1-event.
5. Log in to the undercloud host as the stack user.

6. Source the stackrc undercloud credentials file:

   $ source stackrc

   Copy to Clipboard Toggle word wrap

7. Include the stf-connectors.yaml file and unique domain name environment file hostnames.yaml in the openstack overcloud deployment command, with any other environment files relevant to your environment:

   Warning

   If you use the collectd-write-qdr.yaml file with a custom CollectdAmqpInstances parameter, data publishes to the custom and default topics. In a multiple cloud environment, the configuration of the resource_registry parameter in the stf-connectors.yaml file loads the collectd service.

   (undercloud)$ openstack overcloud deploy --templates \

4. Add retention: 7d to the storage section of backends.metrics.prometheus.storage to increase the retention period to seven days:

   Note

   If you set a long retention period, retrieving data from heavily populated Prometheus systems can result in queries returning results slowly.

   apiVersion: infra.watch/v1beta1
   kind: ServiceTelemetry
   metadata:
     name: default
     namespace: service-telemetry
   spec:

3. Create a PrometheusRule object that contains the alert rule. The Prometheus Operator loads the rule into Prometheus:

   $ oc apply -f - <<EOF
   apiVersion: monitoring.coreos.com/v1
   kind: PrometheusRule
   metadata:
     creationTimestamp: null
     labels:
       prometheus: default

     name: prometheus-alarm-rules
     namespace: service-telemetry
   spec:
     groups:
       - name: ./openstack.rules
         rules:
           - alert: Collectd metrics receive rate is zero
             expr: rate(sg_total_collectd_msg_received_count[1m]) == 0
   EOF

   Copy to Clipboard Toggle word wrap

   To change the rule, edit the value of the expr parameter.

4. To verify that the Operator loaded the rules into Prometheus, run the curl command against the default-prometheus-proxy route with basic authentication:

   $ curl -k --user "internal:$(oc get secret default-prometheus-htpasswd -ogo-template='{{ .data.password | base64decode }}')" https://$(oc get route default-prometheus-proxy -ogo-template='{{ .spec.host }}')/api/v1/rules

3. Edit the ServiceTelemetry object for your STF deployment:

   $ oc edit stf default

   Copy to Clipboard Toggle word wrap

4. Add the new parameter alertmanagerConfigManifest and the Secret object contents to define the alertmanager.yaml configuration for Alertmanager:

   Note

   This step loads the default template that the Service Telemetry Operator manages. To verify that the changes are populating correctly, change a value, return the alertmanager-default secret, and verify that the new value is loaded into memory. For example, change the value of the parameter global.resolve_timeout from 5m to 10m.

   apiVersion: infra.watch/v1beta1
   kind: ServiceTelemetry
   metadata:
     name: default
     namespace: service-telemetry

   Copy to Clipboard Toggle word wrap

5. Verify that the configuration has been applied to the secret:

   $ oc get secret alertmanager-default -o go-template='{{index .data "alertmanager.yaml" | base64decode }}'
   
   global:
     resolve_timeout: 10m
   route:
     group_by: ['job']
     group_wait: 30s
     group_interval: 5m
     repeat_interval: 12h
     receiver: 'null'
   receivers:
   - name: 'null'

   Copy to Clipboard Toggle word wrap

6. Run the wget command from the prometheus pod against the alertmanager-proxy service to retrieve the status and configYAML contents, and verify that the supplied configuration matches the configuration in Alertmanager:

   $ oc exec -it prometheus-default-0 -c prometheus -- sh -c "wget --header \"Authorization: Bearer \$(cat /var/run/secrets/kubernetes.io/serviceaccount/token)\" https://default-alertmanager-proxy:9095/api/v1/status -q -O -"
   
   {"status":"success","data":{"configYAML":"...",...}}

   Copy to Clipboard Toggle word wrap

3. Create the necessary alertmanager config in a file called alertmanager.yaml, for example:

   $ cat > alertmanager.yaml <<EOF
   global:
     resolve_timeout: 10m
     slack_api_url: <slack_api_url>
   receivers:
     - name: slack
       slack_configs:
       - channel: #stf-alerts
         title: |-
           ...
         text: >-
           ...
   route:
     group_by: ['job']
     group_wait: 30s
     group_interval: 5m
     repeat_interval: 12h
     receiver: 'slack'
   EOF

4. Generate the config manifest and add it to the ServiceTelemetry object for your STF deployment:

   $ CONFIG_MANIFEST=$(oc create secret --dry-run=client generic alertmanager-default --from-file=alertmanager.yaml -o json)
   $ oc patch stf default --type=merge -p '{"spec":{"alertmanagerConfigManifest":'"$CONFIG_MANIFEST"'}}'

   Copy to Clipboard Toggle word wrap

5. Verify that the configuration has been applied to the secret:

   Note

   There will be a short delay as the operators update each object

   $ oc get secret alertmanager-default -o go-template='{{index .data "alertmanager.yaml" | base64decode }}'
   
   global:
     resolve_timeout: 10m
     slack_api_url: <slack_api_url>
   receivers:
     - name: slack
       slack_configs:
       - channel: #stf-alerts
         title: |-
           ...
         text: >-
           ...
   route:
     group_by: ['job']
     group_wait: 30s
     group_interval: 5m
     repeat_interval: 12h
     receiver: 'slack'

   Copy to Clipboard Toggle word wrap

6. Run the wget command from the prometheus pod against the alertmanager-proxy service to retrieve the status and configYAML contents, and verify that the supplied configuration matches the configuration in Alertmanager:

   $ oc exec -it prometheus-default-0 -c prometheus -- /bin/sh -c "wget --header \"Authorization: Bearer \$(cat /var/run/secrets/kubernetes.io/serviceaccount/token)\" https://default-alertmanager-proxy:9095/api/v1/status -q -O -"
   
   {"status":"success","data":{"configYAML":"...",...}}

3. To enable SNMP traps, modify the ServiceTelemetry object:

   $ oc edit stf default

   Copy to Clipboard Toggle word wrap

4. Set the alerting.alertmanager.receivers.snmpTraps parameters:

   apiVersion: infra.watch/v1beta1
   kind: ServiceTelemetry
   ...
   spec:
     ...
     alerting:
       alertmanager:
         receivers:
           snmpTraps:
             enabled: true
             target: 10.10.10.10

3. Create a PrometheusRule object that contains the alert rule and an oid label that contains the SNMP trap OID override value:

   $ oc apply -f - <<EOF
   apiVersion: monitoring.coreos.com/v1
   kind: PrometheusRule
   metadata:
     creationTimestamp: null
     labels:
       prometheus: default
       role: alert-rules
     name: prometheus-alarm-rules-snmp
     namespace: service-telemetry
   spec:
     groups:
       - name: ./openstack.rules
         rules:
           - alert: Collectd metrics receive rate is zero
             expr: rate(sg_total_collectd_msg_received_count[1m]) == 0
             labels:
               oid: 1.3.6.1.4.1.50495.15.1.2.1
               severity: critical
   EOF

Verification

1. Verify that the expiry date for the certificates is correct:

   $ oc get secret elasticsearch-es-cert -o jsonpath='{.data.tls\.crt}' | base64 -d  | openssl x509 -in - -text | grep "Not After"
               Not After : Mar  9 21:00:16 2026 GMT
   
   $ oc get secret  default-interconnect-selfsigned -o jsonpath='{.data.tls\.crt}' | base64 -d  | openssl x509 -in - -text | grep "Not After"
               Not After : Mar  9 21:00:16 2033 GMT
