The AppDynamics Agent Framework causes an application to be automatically configured to work with a bound AppDynamics Service.
| Detection Criterion | Existence of a single bound AppDynamics service. The existence of an AppDynamics service defined by the VCAP_SERVICES payload containing a service name, label or tag with app-dynamics or appdynamics as a substring.
|
| Tags | app-dynamics-agent=<version> |
When binding AppDynamics using a user-provided service, it must have name or tag with app-dynamics or appdynamics in it. The credential payload can contain the following entries:
| Name | Description |
|---|---|
account-access-key |
(Optional) The account access key to use when authenticating with the controller |
account-name |
(Optional) The account name to use when authenticating with the controller |
application-name |
(Optional) the applicationa's name |
host-name |
The controller host name |
node-name |
(Optional) the application's node name |
port |
(Optional) The controller port |
ssl-enabled |
(Optional) Whether or not to use an SSL connection to the controller |
tier-name |
(Optional) the application's tier name |
To provide more complex values such as the tier-name, using the interactive mode when creating a user-provided service will manage the character escaping automatically. For example, the default tier-name could be set with a value of Tier-$(expr "$VCAP_APPLICATION" : '.*instance_index[": ]*\([[:digit:]]*\).*') to calculate a value from the Cloud Foundry instance index.
For general information on configuring the buildpack, including how to specify configuration values through environment variables, refer to Configuration and Extension.
The framework can be configured by modifying the config/appdynamicsagent.yml file in the buildpack fork. The framework uses the Repository utility support and so it supports the version syntax defined there.
| Name | Description |
|---|---|
default_application_name |
This is omitted by default but can be added to specify the application name in the AppDynamics dashboard. This can be overridden by an application-name entry in the credentials payload. If neither are supplied the default is the application_name as specified by Cloud Foundry. |
default_node_name |
The default node name for this application in the AppDynamics dashboard. The default value is an expression that will be evaluated based on the instance_index of the application. This can be overridden by a node-name entry in the credentials payload. |
default_tier_name |
This is omitted by default but can be added to specify the tier name for this application in the AppDynamics dashboard. This can be overridden by a tier-name entry in the credentials payload. If neither are supplied the default is the application_name as specified by Cloud Foundry. |
repository_root |
The URL of the AppDynamics repository index (details). |
version |
The version of AppDynamics to use. Candidate versions can be found in this listing. |
The framework can also be configured by overlaying a set of resources on the default distribution. To do this, add files to the resources/appdynamics_agent directory in the buildpack fork. For example, to override the default appdynamics.yml add your custom file to resources/appdynamics_agent/appdynamics.yml.
