Netflix Servo应用运行指标监控

Netflix Servo 用 Java 语言，提供暴露、发布应用运行指标的简单接口，主要满足的需求包括：使用JMX、简单、灵活发布。

示例代码：

public class Server {

    @MonitorId

    private final String id;



    @Monitor(name="Status", type=INFORMATIONAL)

    private AtomicReference<String> status = new AtomicReference<String>("UP");



    @Monitor(name="CurrentConnections", type=GAUGE)

    private AtomicInteger currentConnections = new AtomicInteger(0);



    @Monitor(name="TotalConnections", type=COUNTER)

    private AtomicInteger totalConnections = new AtomicInteger(0);



    @Monitor(name="BytesIn", type=COUNTER)

    private AtomicLong bytesIn = new AtomicLong(0L);



    @Monitor(name="BytesOut", type=COUNTER)

    private AtomicLong bytesOut = new AtomicLong(0L);



    public Server(String id) {

        this.id = id;

    }



    // ...

}



Server s1 = new Server("s1");

DefaultMonitorRegistry.getInstance().registerObject(s1);
