After you install the Application Real-Time Monitoring Service (ARMS) agent for a Java application that is deployed in a Docker cluster, ARMS starts to monitor the Java application. ARMS automatically adapts to the environment where the application runs. You do not need to set up the runtime environment for Tomcat, Jetty, or Spring Boot applications. This topic describes how to install the ARMS agent for a Java application that is deployed in a Docker cluster.

Prerequisites

  • ARMS is activated. For more information, see Activate and upgrade ARMS.
  • A Java application is deployed in a Docker cluster.
  • If the JDK Version is 1.8.0_25 or 1.8.0_31, you may fail to install the arms Agent. In this case, upgrade the JDK version to the latest version, which is 1.8.X.

Background information

ARMS Application Monitoring allows you to monitor Java applications by using the {original-docker-image:tag} image. To do so, edit the Dockerfile file to integrate an existing image. Then, build and start a new image.

Step 1: Obtain the license key

  1. Log on to the ARMS console .
  2. In the left-side navigation pane, choose Application Monitoring > Applications. In the top navigation bar, select a region.
  3. On the Applications page, click Add Application.
  4. In the Backend Applications section of the Integration Center panel, click Java.
    Manually install a Java application
  5. In the upper-right corner of the Integrate Java panel, select the region in which you want to install the Java application.
  6. Obtain the license key in the STEP2 section.
    Section LicenseKey

Step 2: Integrate an existing image

Edit the Dockerfile file, as shown in the following example.

Replace the example values in the preceding configuration file based on the following instructions.

  • Replace {original-docker-image:tag} with your image address. If you do not have a custom image, use a system image instead.
  • Replace the link for downloading the ARMS agent based on your region.
    Note Use the public endpoint. If the download fails, use the VPC endpoint.

  • Replace {LicenseKey} with your license key. Replace {AppName} with the name of your application. The application name cannot contain Chinese characters.

Step 3: Build and start a new image

  1. Run the docker build command to build an image.
    docker build -t registry.cn-hangzhou.aliyuncs.com/arms-docker-repo/arms-springboot-demo:v0.1 -f /{workspace}/Dockerfile /{workspace}/
    Note Replace registry.cn-hangzhou.aliyuncs.com/arms-docker-repo/arms-springboot-demo:v0.1 with the actual image name.
  2. Run the docker run command to start the image.
    docker run -d -p 8081:8080 registry.cn-hangzhou.aliyuncs.com/arms-docker-repo/arms-springboot-demo:v0.1
    Note Replace registry.cn-hangzhou.aliyuncs.com/arms-docker-repo/arms-springboot-demo:v0.1 with the actual image name.

Verify the result

After about 1 minute, if your application is displayed in the application list and some data records are sent, it indicates that your application is monitored by ARMS.

Uninstall the ARMS agent

If you no longer need to monitor the Java application in the Docker cluster, perform the following steps to uninstall the ARMS agent:

  1. Delete the configurations that you added to the Dockerfile file in Step 2: Integrate an existing image.
  2. Run the docker build command to build an image.
  3. Run the docker run command to start the image.
