application.properties file example:

metrics.export.username: admin
metrics.export.password: secret
metrics.export.url: http://atsd_hostname:8088/api/v1/command
metrics.export.bufferSize: 16
metrics.names.entity: spring-boot-sample
metrics.names.metricPrefix: spring-boot
metrics.names.tags.ip: 127.0.0.1
metrics.names.tags.organization: Axibase

Metrics

Refer to AtsdNamingStrategy and AtsdMetricWriter example.

Enable public metrics export:

@Bean
    public MetricsEndpointMetricReader metricsEndpointMetricReader(MetricsEndpoint metricsEndpoint) {
        return new MetricsEndpointMetricReader(metricsEndpoint);
    }

        @Bean
    @ExportMetricWriter
    @ConfigurationProperties("metrics.export")
    public MetricWriter atsdMetricWriter() {
        AtsdMetricWriter writer = new AtsdMetricWriter();
        writer.setNamingStrategy(namingStrategy());
        return writer;
    }

    @Bean
    @ConfigurationProperties("metrics.names")
    public AtsdNamingStrategy namingStrategy() {
        return new DefaultAtsdNamingStrategy();
    }

Wrapping Methods using Custom Metrics

Wrap all class methods.

@Measured
public class JdbcCityRepository implements CityRepository

Wrap a specific method.


@Measured
 public List<City> findCities()
