CloudFoundry
Status: Experimental

CloudFoundry organizes application deployments (apps) by spaces contained in organizations (orgs). Names are unique only in their respective enclosing entity. Ids are unique in the entire CloudFoundry installation. Different instances of the same application are separated by an integer index. Apps can consist of a main job and multiple tasks and side-cars, which can be distinguished by different process attributes.
CloudFoundry can also emit signals from system components. They use a different approach as applications, since they are not organized into orgs and spaces. They align with the Bosh deployment tool of CloudFoundry.
Organization
Status:
type: cloudfoundry.org
Description: The organization of the application which is monitored.
| Attribute | Type | Description | Examples | Requirement Level | Stability |
|---|---|---|---|---|---|
cloudfoundry.org.id | string | The guid of the CloudFoundry org the application is running in. [1] | 218fc5a9-a5f1-4b54-aa05-46717d0ab26d | Recommended |  |
cloudfoundry.org.name | string | The name of the CloudFoundry organization the app is running in. [2] | my-org-name | Recommended | |
[1]: Application instrumentation should use the value from environment
variable VCAP_APPLICATION.org_id. This is the same value as
reported by cf org <org-name> --guid.
[2]: Application instrumentation should use the value from environment
variable VCAP_APPLICATION.org_name. This is the same value as
reported by cf orgs.
Space
Status:
type: cloudfoundry.space
Description: The space of the application which is monitored.
| Attribute | Type | Description | Examples | Requirement Level | Stability |
|---|---|---|---|---|---|
cloudfoundry.space.id | string | The guid of the CloudFoundry space the application is running in. [1] | 218fc5a9-a5f1-4b54-aa05-46717d0ab26d | Recommended | |
cloudfoundry.space.name | string | The name of the CloudFoundry space the application is running in. [2] | my-space-name | Recommended | |
[1]: Application instrumentation should use the value from environment
variable VCAP_APPLICATION.space_id. This is the same value as
reported by cf space <space-name> --guid.
[2]: Application instrumentation should use the value from environment
variable VCAP_APPLICATION.space_name. This is the same value as
reported by cf spaces.
Application
Status:
type: cloudfoundry.app
Description: The application which is monitored.
| Attribute | Type | Description | Examples | Requirement Level | Stability |
|---|---|---|---|---|---|
cloudfoundry.app.id | string | The guid of the application. [1] | 218fc5a9-a5f1-4b54-aa05-46717d0ab26d | Recommended | |
cloudfoundry.app.name | string | The name of the application. [2] | my-app-name | Recommended | |
[1]: Application instrumentation should use the value from environment
variable VCAP_APPLICATION.application_id. This is the same value as
reported by cf app <app-name> --guid.
[2]: Application instrumentation should use the value from environment
variable VCAP_APPLICATION.application_name. This is the same value
as reported by cf apps.
Process
Status:
type: cloudfoundry.process
Description: The process of the application which is monitored.
| Attribute | Type | Description | Examples | Requirement Level | Stability |
|---|---|---|---|---|---|
cloudfoundry.process.id | string | The UID identifying the process. [1] | 218fc5a9-a5f1-4b54-aa05-46717d0ab26d | Recommended | |
cloudfoundry.process.type | string | The type of process. [2] | web | Recommended | |
[1]: Application instrumentation should use the value from environment
variable VCAP_APPLICATION.process_id. It is supposed to be equal to
VCAP_APPLICATION.app_id for applications deployed to the runtime.
For system components, this could be the actual PID.
[2]: CloudFoundry applications can consist of multiple jobs. Usually the
main process will be of type web. There can be additional background
tasks or side-cars with different process types.
Cloud Foundry System Component
Status:
type: cloudfoundry.system
Description: The system component which is monitored.
| Attribute | Type | Description | Examples | Requirement Level | Stability |
|---|---|---|---|---|---|
cloudfoundry.system.id | string | A guid or another name describing the event source. [1] | cf/gorouter | Recommended | |
cloudfoundry.system.instance.id | string | A guid describing the concrete instance of the event source. [2] | 218fc5a9-a5f1-4b54-aa05-46717d0ab26d | Recommended | |
[1]: CloudFoundry defines the source_id in the Loggregator v2 envelope.
It is used for logs and metrics emitted by CloudFoundry. It is
supposed to contain the component name, e.g. “gorouter”, for
CloudFoundry components.
When system components are instrumented, values from the
Bosh spec
should be used. The system.id should be set to
spec.deployment/spec.name.
[2]: CloudFoundry defines the instance_id in the Loggregator v2 envelope.
It is used for logs and metrics emitted by CloudFoundry. It is
supposed to contain the vm id for CloudFoundry components.
When system components are instrumented, values from the
Bosh spec
should be used. The system.instance.id should be set to spec.id.
