How to monitor the latency?

[FatMouse]

    Hello:

I hava set the LatencyTrackingInterval as 2000,but int the `Task Metrics` latency was always Nan.How can I monitor the latency?Thanks.

Code:

StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();

env.getConfig().setLatencyTrackingInterval(2000);

Best,

As far as I know, as for using the latency metric, only the JMXReporter now.

Correct, in pre-1.5 the latency metric can only be used via the JMXReporter.
With 1.5 you will be able to access the latency metric via any reporter of the REST API, but as it stands still not the WebUI.
