Timer is not generating any metrics

[Sreejith S]

Hi All, 

I am new to metrics. When i tried with Timer , the report always like below

get-requests

             count = 0

         mean rate = 0.00 calls/second

     1-minute rate = 0.00 calls/second

     5-minute rate = 0.00 calls/second

    15-minute rate = 0.00 calls/second

               min = 0.00 milliseconds

               max = 0.00 milliseconds

              mean = 0.00 milliseconds

            stddev = 0.00 milliseconds

            median = 0.00 milliseconds

              75% <= 0.00 milliseconds

              95% <= 0.00 milliseconds

              98% <= 0.00 milliseconds

              99% <= 0.00 milliseconds

            99.9% <= 0.00 milliseconds

And i am using a sample code like this

final Timer timer = metricRegistry.timer("get-requests");

final Timer.Context context = timer.time();

try {

for(int i=0;i<100;i++) {

counter.inc();

me.mark();

Thread.sleep(1000);

}

} finally {

   context.stop();

}

Is this the right way to do ?

Are you waiting the 100 seconds for the loop to complete? Looks okay assuming you're waiting for that sleep loop to complete (which would take 100 seconds). Is the meter and counter you're incrementing in the loop working correctly for you?

Yes Ryan I am able to see Counter and Meter metrics like below

-- Counters --------------------------------------------------------------------

counter

             count = 78

-- Meters ----------------------------------------------------------------------

requests

             count = 78

         mean rate = 1.00 events/second

     1-minute rate = 1.00 events/second

     5-minute rate = 1.00 events/second

    15-minute rate = 1.00 events/second

But , timer count is always 0.

Any pointers on this ?
