Micrometer AppOptics

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

1. Installing micrometer-registry-appoptics

For Gradle, add the following implementation:

implementation 'io.micrometer:micrometer-registry-appoptics:latest.release'

For Maven, add the following dependency:


2. Configuring

The following example configures an AppOptics instance:

AppOpticsConfig appopticsConfig = new AppOpticsConfig() {
    public String apiToken() {
        return MY_TOKEN;

    public String get(String k) {
        return null;
MeterRegistry registry = new AppOpticsMeterRegistry(appopticsConfig, Clock.SYSTEM);

AppOpticsConfig 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.appoptics directly to the AppOpticsConfig:

    api-token: YOURKEY

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

    # The interval at which metrics are sent to AppOptics. The default is 1 minute.
    step: 1m

3. Graphing

This section serves as a quick start to rendering useful representations in AppOptics for metrics that originate in Micrometer.

3.1. Timers

The AppOptics implementation of Timer produces three fields in AppOptics:

  • count: Rate of number of calls/second.

  • sum: Rate of total time/second.

  • max: A sliding window showing the maximum amount recorded.

AppOptics performs the sum/count division dimensionally to generate aggregable averages on your behalf.
