Deploy OneAgent on Pivotal Web Services for application-only monitoring
Applications deployed on Cloud Foundry are usually run through technology-specific buildpacks that provide framework and runtime support for applications running on the Cloud Foundry platform. For complete details, see how buildpacks work.
When deployed in application-only mode, OneAgent monitors the memory, disk, CPU, and networking of processes within the container only. Host metrics aren't monitored.
Prerequisites
- Create a PaaS Token.
- Review the Supported applications and versions.
Deploy OneAgent
-
Create a Dynatrace service in your Cloud Foundry environment.
There are three ways of defining a service instance, choose one of them:Create a single service instance for Dynatrace with the name
dynatraceas a substring (for example,dynatrace-service) using the command below. The command should include the parametersenvironmentidandapitokenwritten exactly as shown below. Once the command is executed, you'll be prompted to enter your environment ID and API token. The API token corresponds to the PaaS token mentioned above.The code examples below use the
cfCLI for interfacing with Cloud Foundry clusters.1cf cups dynatrace-service -p "environmentid, apitoken"If you want to maintain Dynatrace credentials in a central location, use a service broker. For complete details, visit GitHub. You must configure and run the broker as an application, add the service broker to Cloud Foundry, enable service access to users, and finally, create the service instance.
If you run a VMware Tanzu Platform environment, you can make use of the Dynatrace Service Broker tile on the VMware Tanzu Network.

Bind Dynatrace service to your application
You can bind the created Dynatrace service to your application in your
manifest.ymlfile. If your application is already started, you need to restage it.See the example below for pushing a Java application.
1---2applications:3- name: spring-music4 memory: 768M5 instances: 16 host: spring-music-${random-word}7 path: spring-music.war8 buildpack: https://github.com/cloudfoundry/java-buildpack.git9services:10 - dynatrace-service -
optional Configure the default OneAgent log stream for Cloud Foundry.
By default, OneAgent logs are written to the Cloud Foundry standard error stream. All you have to do is set the environment variable
DT_LOGSTREAMto eitherstdoutorstderr.For example:
1cf set-env APP_NAME DT_LOGSTREAM stdout -
optional Configure a proxy address.
If your environment uses a proxy, you need to set the
DT_PROXYenvironment variable to pass the proxy credentials to OneAgent as shown below.1cf set-env <application> DT_PROXY <proxy address> -
optional Configure network zones.
You can configure network zones in two ways.

UserProvidedService:
1cf cups dynatrace-service -p "environmentid, apitoken, networkzone"As an environment variable per application:
1cf set-env <application> DT_NETWORK_ZONE <your_network_zone>See network zones for more information.
