Application Real-Time Monitoring Service:Start monitoring multi-container applications in a single pod

Prerequisite

The ack-onepilot version must be 4.2.0 or later.

Procedure

1. Refer to the following documents to install ack-onepilot and grant the appropriate resource access permissions:

   • Install Java agent through ack-onepilot component in Container Service for Kubernetes and Container Compute Service

   • Automatically install agent in general Kubernetes environment

2. Add relevant tags to the workload.

   The YAML above represents a complex application that simultaneously uses Java, Golang, and Python programming languages. The application contains three containers with different programming languages, named test-java, test-go, and test-python.

   You can connect these three containers to three different ARMS applications to achieve data isolation. Follow these steps:

   1. Log on to the ACK console. In the left navigation pane, click Clusters.

   2. On the Clusters page, find the cluster you want to manage and click its name. In the left navigation pane, choose Workloads > Deployments.

   3. On the Deployments page, click > Edit YAML on the right side of the target application.

      To create a new application, click Create From YAML.

   4. Add the following labels to the spec.template.metadata level in the YAML file, and then click Update.

      labels:
        # Please replace ${containerName} with the actual container name
        apsara.apm/container.${containerName}.app-language: java # Replace with the actual programming language of the container
        apsara.apm/container.${containerName}.armsPilotAutoEnable: 'on'
        apsara.apm/container.${containerName}.armsPilotCreateAppName: "<your-deployment-name>"    # Please replace <your-deployment-name> with your application name.

3. If the application appears on the Application Monitoring > Application List page in the ARMS console and data is being reported, the connection is successful.
