Monitor services

The monitoring endpoint described in this section is deprecated. Use it only for diagnostics, in conjunction with Forgerock support.

A monitoring endpoint provides access to metrics for operations within the agent and between the agent an AM.

The monitoring endpoint is protected by HTTP Basic Authentication; to access it, provide the agent URL, and the AM agent profile name and password. Always use HTTPS for secure connections to client applications.

Metrics are displayed as a JSON response, with the fields described in Summary of monitoring metrics.

Access the monitoring endpoint

Install a Web Agent as described in the Installation, and use the agent to protect a web application. For example, set up the example in Policy enforcement.
Access the agent monitoring endpoint as follows, where https://agent.example.com:443 is the agent URL, and web-agent is the AM agent profile name.
```
$ curl https://agent.example.com:443/agent/monitor -u web-agent

Enter host password for user 'web-agent':
```

Enter the AM agent profile password to display the metrics:
