Examples with Id io.micrometer.core.instrument.Meter.Id used on opensource projects

Example 1 with Id

use of io.micrometer.core.instrument.Meter.Id in project micrometer by micrometer-metrics.

the class MeterRegistry method registerMeterIfNecessary.

private <M extends Meter> M registerMeterIfNecessary(Class<M> meterClass, Meter.Id id, @Nullable DistributionStatisticConfig config, BiFunction<Meter.Id, DistributionStatisticConfig, Meter> builder, Function<Meter.Id, M> noopBuilder) {
    Meter.Id mappedId = id;

                config = filteredConfig;
            }

    }
    Meter m = getOrCreateMeter(config, builder, mappedId, noopBuilder);
    if (!meterClass.isInstance(m)) {
        throw new IllegalArgumentException("There is already a registered meter of a different type with the same name");
    }
    // noinspection unchecked
    return (M) m;
}

Example 2 with Id

use of io.micrometer.core.instrument.Meter.Id in project micrometer by micrometer-metrics.

the class MeterRegistry method newTimeGauge.

/**
 * Build a new time gauge to be added to the registry. This is guaranteed to only be called if the time gauge doesn't already exist.
 *
 * @param id                The id that uniquely identifies the time gauge.
 * @param obj               The state object from which the value function derives a measurement.
 * @param valueFunctionUnit The base unit of time returned by the value function.
 * @param valueFunction     A function returning a time value that can go up or down.
 * @param <T>               The type of the object upon which the value function derives a measurement.
 * @return A new time gauge.
