Example 1 with TimerContext

use of org.springside.modules.metrics.metric.Timer.TimerContext in project springside4 by springside.

the class MetricExamples method timerExample.

@Test
public void timerExample() throws InterruptedException {
    MetricRegistry metricRegistry = new MetricRegistry();
    // 使用slf4j reporter,并使用自定义logger名字

    ReportScheduler scheduler = new ReportScheduler(metricRegistry);
    scheduler.addReporter(slf4jReporter);
    scheduler.start(1, TimeUnit.SECONDS);
    Timer timer = metricRegistry.timer(MetricRegistry.name("UserService", "getUser.timer"), new Double[] { 99d, 99.99d });
    // 写法1
    TimerContext timerContext = timer.start();

    timerContext.stop();
    timerContext = timer.start();
    Thread.sleep(200);
