2 Metrics Endpoint

Using the CLI

If you are creating your project using the Micronaut CLI, supply one of micrometer-atlas, micrometer-graphite, micrometer-prometheus, or micrometer-statsd features to enable metrics and preconfigure the selected registery in your project:

$ mn create-app my-app --features micrometer-atlas

The metrics endpoint returns information about the "metrics" of the application. To execute the metrics endpoint, send a GET request to /metrics. This will return a list of the metric names registered with the MeterRegistry bean.

You can get specific metrics by using /metrics/[name] such as /metrics/jvm.memory.used. This would return something like:

Sample Metric Detail Json
{
  "name": "jvm.memory.used",
  "measurements": [
    {
      "statistic": "VALUE",
      "value": 1.45397552E8
    }
  ],
  "availableTags": [
    {
      "tag": "area",
      "values": [
        "heap",
        "nonheap"
      ]
    },
    {
      "tag": "id",
      "values": [
        "Compressed Class Space",
        "PS Survivor Space",
        "PS Old Gen",
        "Metaspace",
        "PS Eden Space",
        "Code Cache"
      ]
    }
  ]
}

You can further limit the metric by using a tag like /metrics/jvm.memory.used?tag=id:PS%20Old%20Gen.

Sample Metric Detail Json
{
  "name": "jvm.memory.used",
  "measurements": [
    {
      "statistic": "VALUE",
      "value": 1.1434488E7
    }
  ],
  "availableTags": [
    {
      "tag": "area",
      "values": [
        "heap"
      ]
    }
  ]
}

You may even use multiple/nested tags like /metrics/jvm.memory.used?tag=id:PS%20Old%20Gen&tag=area:heap.

Sample Metric Detail Json
{
  "name": "jvm.memory.used",
  "measurements": [
    {
      "statistic": "VALUE",
      "value": 1.1434488E7
    }
  ]
}

Configuration

Currently the metrics endpoint will only be enabled if you include the micrometer-core (or one of the typed registries such as micrometer-registry-statsd or micrometer-registry-graphite) AND the management dependencies. You will also need to have the global metrics flag enabled (true by default).

Property
micronaut:
  metrics:
    enabled: true
Gradle
dependencies {
    ...
    compile "io.micronaut.configuration:micronaut-micrometer-core"
    // micrometer-registry-statsd also pulls in micrometer-core so included above to verbose example
    compile "io.micronaut.configuration:micronaut-micrometer-registry-statsd"
    // Also required to enable endpoint
    compile "io.micronaut:micronaut-management"
    ...
}
Maven
<dependency>
  <groupId>io.micronaut.configuration</groupId>
  <artifactId>micronaut-micrometer-core</artifactId>
  <version>${micronaut.version}</version>
</dependency>
<!-- micrometer-registry-statsd also pulls in micrometer-core so included above to verbose example -->

</dependency>
<!-- Also required to enable endpoint -->
<dependency>

To configure the metrics endpoint, supply configuration through endpoints.metrics.

3 Metrics Concepts

Metric Concepts

Key Micrometer.io concepts include a MeterRegistry to register and use meters. A Meter is something that produces metrics.

A MeterRegistry can have some customizations automatically applied.

Meter Registry Configurer

  • Any bean that implements MeterRegistryConfigurer gets applied to every applicable MeterRegistry bean on creation

  • The implementation of the MeterRegistryConfigurer supports() method determines if the configurer is applied to a particular registry

    • If you want all registries to get the customization, simply return return true

    • Otherwise, you can evaluate the registry for its class type, its class hierarchy, or other criteria.

    • Remember you only get one shot for autoconfiguration; i.e. when the bean context is started.

    • However, in code, you can apply additional customizations to the registry config

    }

    @Override
    public boolean supports(MeterRegistry meterRegistry) {
        return meterRegistry instanceof SimpleMeterRegistry;
    }
}

Meter Filter

  • A meter filter can be used to determine if a Meter is to be added to the registry. See Meter Filters

  • Any bean that implements MeterFilter will be applied to all registries when the registry is first created

You can create custom filters similar to the following inside your application. Micrometer’s MeterFilter class provides several convenience methods to help with the creation of these filters.

Meter Binder

Meter Binders get applied to Meter Registry to mix in metrics producers. Micrometer.io defines several of these for cross-cutting metrics related to JVM metrics, caches, classloaders, etc. These all extend a simple interface MeterBinder, but these are not auto wired as beans and manual wiring is required given how micrometer is currently implemented.

Provided Binders

The following metrics currently have binders and are enabled by default. The settings listed below can disable the specific metric binders if you do not with to collect or report the specific metrics.

Jvm Metrics

The JVM metrics bindings will provide several jvm metrics.

Control Property: micronaut.metrics.binders.jvm.enabled

Table 1. Metrics provided

Name

jvm.buffer.count

jvm.buffer.memory.used

jvm.buffer.total.capacity

jvm.classes.loaded

jvm.gc.memory.promoted

jvm.memory.committed

jvm.memory.max

jvm.memory.used

jvm.threads.daemon

jvm.threads.live

jvm.threads.peak
Web Metrics

There is a default web filter provided for web metrics. All routes, status codes, methods and exceptions will be timed and counted.

Control Property: micronaut.metrics.binders.web.enabled

Filter Path

If enabled, be default the path /** will be intercepted. If you wish to change which paths are run through the filter set the following property.

Control Property: micronaut.metrics.http.path

Table 2. Metrics provided

Name

http.server.requests

http.client.requests
System Metrics

There are multiple metrics that can be separately toggled.

Uptime Metrics

The uptime metrics bindings will provide system uptime metrics.

Table 3. Metrics provided

Name

process.uptime

process.start.time
Processor Metrics

The processor metrics bindings will provide system processor metrics.

Logback Metrics

The logging metrics bindings will provide logging metrics if using Logback.

Control Property: micronaut.metrics.binders.logback.enabled

Table 6. Metrics provided

Hibernate Metrics

You can enable metrics for Hibernate by setting the hibernate.generate_statistics property to true in configuration. For example for the default entity manager:

Enabling Hibernate Metrics

jpa:
    default:
        properties:
            hibernate:
                generate_statistics: true

Micrometer will automatically expose Hibernate statistics. See the source code for HibernateMetrics for the available metrics.

DataSource Metrics

The data source metrics bindings will provide data source pool metrics.

Control Property: micronaut.metrics.binders.jdbc.enabled

There is a different set of pool metric names for HikariCP and other pool providers.

If you are using io.micronaut.configuration:micronaut-jdbc-hikari you will get additional pool metrics as HikariCP has built in support for meter registries.

Table 7. HikariCP Metrics Provided

hikaricp.connections.idle

hikaricp.connections.pending

hikaricp.connections.active

hikaricp.connections.creation

hikaricp.connections.usage

hikaricp.connections.timeout

hikaricp.connections.acquire

If you are using io.micronaut.configuration:micronaut-jdbc-tomcat or io.micronaut.configuration:micronaut-jdbc-dbcp you will get the following metrics

Table 8. Generic Pool Metrics provided

Name

jdbc.connections.usage

jdbc.connections.active

Adding Custom Metrics

To add metrics to your application you can inject a MeterRegistry bean to your class and use the provided methods to access counters, timers, etc.

See the Micrometer.io docs at https://micrometer.io/docs for more information.
