Java Agents 2024.9

Monitor services

The following sections describe how to set up and maintain monitoring in your deployment to ensure appropriate performance and service availability.

The Prometheus endpoint isn’t currently supported for Jakarta builds of the agent because of known issue AMAGENTS-6809.

Monitor with Prometheus

Java Agent automatically exposes a monitoring endpoint where Prometheus can scrape metrics in a standard Prometheus format (version 0.0.4).

The Prometheus endpoint is enabled by default. You can disable it if required by setting the Enable Prometheus Monitoring property to false.

You can find information about installing and running Prometheus in the Prometheus documentation.

Prometheus performance metrics are provided by an endpoint configured in the protected web application’s web.xml file. The endpoint must be accessible to the Prometheus server that uses the performance data.

Tools such as Grafana are available to create customized charts and graphs based on the information collected by Prometheus. Learn more on the Grafana website.

Expose the Prometheus endpoint

Use the following procedure to expose the Prometheus endpoint.

  1. For each protected web application that is to expose metrics, edit the web.xml file for the agentapp application.

    The following example exposes a base endpoint named /metrics:

    <servlet>
   <servlet-name>AgentMonitoring</servlet-name>
   <servlet-class>org.forgerock.http.servlet.HttpFrameworkServlet</servlet-class>
   <init-param>
       <param-name>application-loader</param-name>
       <param-value>service_loader</param-value>
   </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>AgentMonitoring</servlet-name>
    <url-pattern>/metrics/*</url-pattern>
</servlet-mapping>

    Choose a name for the exposed base endpoint that does not conflict with any of the built-in agent endpoints.

  2. Allow access to the Prometheus endpoint that is protected by the agent, in one of the following ways:

    1. Configure Not-Enforced URIs to create a not-enforced URI rule for the base endpoint.

      The following example rule allows access to the metrics base endpoint:

      */metrics/*

    2. Configure Not-Enforced URIs, Not-Enforced Client IP List, and Not-Enforced Compound Rule Separator to create a compound not-enforced rule for the base endpoint.

      The rule allows access from only the IP addresses of the Prometheus server.

      The following example rule allows access to the /metrics endpoint for HTTP requests that come from the IP address range from 192.168.1.1 to 192.168.1.3:

      192.168.1.1-192.168.1.3 | */metrics/*

      HTTP requests from other IP addresses are not able to access the metrics base endpoint.

    3. Create an authorization policy in Advanced Identity Cloud or AM to restrict access to the metrics base endpoint.

      The metric base endpoint doesn’t require login credentials. You can use a policy to ensure that requests to the endpoint are authenticated against the Advanced Identity Cloud or AM instance.

      Learn more in Policies in Advanced Identity Cloud’s Authorization guide or Policies in AM’s Authorization guide.

  3. If the Prometheus endpoint is protected by Advanced Identity Cloud or AM policies, include the required credentials.

Access the Prometheus endpoint

When the example in Expose the Prometheus endpoint is configured, the Prometheus endpoint is available at https://mydomain.example.com/agentapp/metrics/prometheus.

  1. Access the Prometheus endpoint as follows:

    $ curl https://mydomain.example.com/agentapp/metrics/prometheus

    The metrics are displayed:

    # HELP ja_expired_session_cache_eviction the eviction count for the expired session cache
# TYPE ja_expired_session_cache_eviction gauge
ja_expired_session_cache_eviction 0.0
# HELP ja_expired_session_cache the hit count for the expired session cache
# TYPE ja_expired_session_cache gauge
ja_expired_session_cache{outcome="hit",} 0.0
ja_expired_session_cache{outcome="miss",} 0.0
# HELP ja_expired_session_cache_load the total load count for the expired session cache
# TYPE ja_expired_session_cache_load gauge
...

Write metrics to CSV files

Configure Export Monitoring Metrics to CSV to write metric information to CSV files.

Monitoring types

This section describes the data types used in monitoring:

Counter

Cumulative metric for a numerical value that only increases.

Distinct counter

Metric that provides an estimate of the number of unique values recorded.

For example, use this to estimate the number of unique users who have authenticated, or unique client IP addresses.

The DistinctCounter type is reported as a Gauge type.

The DistinctCounter metric is calculated per instance of AM and can’t be aggregated across multiple instances to get a site-wide view.
Gauge

Metric for a numerical value that can increase or decrease.

The value for a gauge is calculated when requested and represents the state of the metric at that specific time.

Timer

Metric that provides duration information.

The Prometheus endpoint doesn’t provide rate-based statistics because rates can be calculated from the time-series data. Instead, the Prometheus endpoint includes summary metrics whose names have the following suffixes or labels:

  • count: number of events recorded

  • sum: sum of the durations recorded

  • {quantile="0.5"}: 50% of the durations are at or below this value

  • {quantile="0.75"}: 75% of the durations are at or below this value

  • {quantile="0.95"}: 95% of the durations are at or below this value

  • {quantile="0.98"}: 98% of the durations are at or below this value

  • {quantile="0.99"}: 99% of the durations are at or below this value

  • {quantile="0.999"}: 99.9% of the durations are at or below this value

The Timer metric type is reported as a Summary type.

Duration-based quantile values are weighted towards newer data. By representing approximately the last five minutes of data, the timers make it easier to see recent changes in behavior, rather than a uniform average of recordings since the server was started.
