Micrometer Azure Monitor

Azure Monitor is a dimensional time-series SaaS with built-in dashboarding.

1. Installing micrometer-registry-azure-monitor

It is recommended to use the BOM provided by Micrometer (or your framework if any), you can see how to configure it here. The examples below assume you are using a BOM.

1.1. Gradle

After the BOM is configured, add the following dependency:

implementation 'io.micrometer:micrometer-registry-azure-monitor'

The version is not needed for this dependency since it is defined by the BOM.

1.2. Maven

After the BOM is configured, add the following dependency:

<dependency>
  <groupId>io.micrometer</groupId>
  <artifactId>micrometer-registry-azure-monitor</artifactId>
</dependency>

The version is not needed for this dependency since it is defined by the BOM.

2. Configuring

The following example configures a Micrometer Azure Monitor:

AzureMonitorConfig azureMonitorConfig = new AzureMonitorConfig() {
    @Override
    public String instrumentationKey() {
        return MY_KEY;
    }

    @Override
    public String get(String key) {
        return null;
    }
};
MeterRegistry registry = new AzureMonitorMeterRegistry(azureMonitorConfig, Clock.SYSTEM);

AzureMonitorConfig is an interface with a set of default methods. If, in the implementation of get(String k), rather than returning null, you instead bind it to a property source, you can override the default configuration. For example, Micrometer’s Spring Boot support binds properties that are prefixed with management.metrics.export.azure-monitor directly to the AzureMonitorConfig:

management.metrics.export.azure-monitor:
    instrumentation-key: YOURKEY

    # You will probably want disable Azure Monitor publishing in a local development profile.
    enabled: true

    # The interval at which metrics are sent to Azure Monitor. The default is 1 minute.
