Step 1: Install APM agentsedit

APM agents are written in the same language as your service. To monitor a new service, you must install the agent and configure it with a service name, APM Server URL, and Secret token or API key.

  • Service name: Service names are used to differentiate data from each of your services. Elastic APM includes the service name field on every document that it saves in Elasticsearch. If you change the service name after using Elastic APM, you will see the old service name and the new service name as two separate services. Make sure you choose a good service name before you get started.

    The service name can only contain alphanumeric characters, spaces, underscores, and dashes (must match ^[a-zA-Z0-9 _-]+$).

  • APM Server URL: The host and port that APM Server listens for events on.
  • Secret token or API key: Authentication method for Agent/Server communication. See secure communication with APM Agents to learn more.

Select your service’s language for installation instructions:
