Most of the a9s Data Services can send Graphite metrics to a Graphite endpoint. The platform operator and application developer can configure those endpoints individually.

The Graphite metrics can be used for monitoring and alerting.

The platform operator can specify a global Graphite endpoint by specifying global_graphite_endpoint in the service manifest. This endpoint will then be configured for all data service instances.

We use the Graphite plaintext protocol to send Graphite metrics.

By default, Graphite metrics generated by the a9s Logstash have the format:

<service_guid>.<data_service>.<host>.<metric> <metric value> <metric timestamp>

Let's assume we have an a9s Messaging instance with the GUID 76816f88-9ada-41cf-99a4-5d6b7adb0e84 running on host d97432b-mq-0.node.dc1.consul. Then the metric path looks like this:


Cloud Foundry Organization and Space

The following feature affects all Graphite metric endpoints, the internal platform operator endpoint discussed in this document mainly, but also the application developer's endpoint(s).

In certain cases it might be beneficial to know the Cloud Foundry organization and space a service instance metric belongs to.

For this purpose the variables use_metrics_prefix_level_2 and use_metrics_prefix_level_3 exist in the service manifest.

The property use_metrics_prefix_level_2 will add the Cloud Foundry organization to the Graphite metric path if set to true.

The property use_metrics_prefix_level_3 will add the Cloud Foundry space to the Graphite metric path if set to true.

To enable support for use_metrics_prefix_level_2 and use_metrics_prefix_level_3, you can also use the Ops file ops/logstash-add-graphite-metrics-level-2-and-3-to-template.yml.

Subsequently, the templates must be uploaded using the Template Uploader Errand and the existing instances must be updated, if necessary, using the Deployment Updater Errand.

For example: a9s Messaging

bosh -d rabbitmq-service deploy rabbitmq-service/rabbitmq-service.yml -l config/iaas-config.yml -l config/rabbitmq.yml -o ops/logstash-add-graphite-metrics-level-2-and-3-to-template.yml
bosh -d rabbitmq-service run-errand templates-uploader
bosh -d rabbitmq-service run-errand deployment_updater


The following is an example of a Graphite metric when both properties are enabled:

68470a75-fd07-4897-b868-16e81fab46a5.fffd9f2a-45c6-4368-8d7a-afab38c0e594.ad6c7e44-ae0f-4c77-8df1-06819fd159ba.postgres.rgd822df8-pg-0.node.dc1.consul-dsf2.ha.master 1 1598884839

The value 68470a75-fd07-4897-b868-11e81fab46a5 is the Cloud Foundry organization and the value fffd9f2a-45c6-4368-8d7a-afab38c0e593 is the Cloud Foundry space, followed by the data service instance GUID ad6c7e44-ae0f-4c77-8df1-06819fd159ba.
