Examples with Get com.linecorp.armeria.server.annotation.Get used on opensource projects

Example 1 with Get

use of com.linecorp.armeria.server.annotation.Get in project zipkin by openzipkin.

the class ZipkinMetricsController method fetchMetricsFromMicrometer.

// Extracts Zipkin metrics to provide backward compatibility
@Get("/metrics")
public HttpResponse fetchMetricsFromMicrometer() throws IOException {
    StringWriter writer = new StringWriter();
    JsonGenerator generator = JsonUtil.createGenerator(writer);
    generator.writeStartObject();
    // Get the Zipkin Custom meters for constructing the Metrics endpoint
    for (Meter meter : meterRegistry.getMeters()) {
        String name = meter.getId().getName();
        if (!name.startsWith("zipkin_collector"))
            continue;
        String transport = meter.getId().getTag("transport");
        if (transport == null)
            continue;
        Meter.Type type = meter.getId().getType();
        if (type == Meter.Type.COUNTER) {
            generator.writeNumberField("counter." + name + "." + transport, ((Counter) meter).count());
        } else if (type == Meter.Type.GAUGE) {
            generator.writeNumberField("gauge." + name + "." + transport, ((Gauge) meter).value());
        }
    // We only use counters and gauges
    }
    generator.writeEndObject();
    // instead of using try/finally as extra indent causes lines to wrap
    generator.flush();
    return HttpResponse.of(HttpStatus.OK, MediaType.JSON, writer.toString());
}
