Hi Foli-
This is code specific to getting Queue stats from a switch using
Beacon. Are you using Beacon as your OpenFlow controller? What stats
are you trying to get?

Hi,
I would like to get statistics from the switches. Please is there any
tutorial explaining how to do this?
I have tried this piece of code that I found online:
public List<OFStatistics> getSwitchQueuesStat(IOFSwitch sw) {
Future<List<OFStatistics>> future;
List<OFStatistics> values = null;
if (sw != null) {
OFStatisticsRequest req = new OFStatisticsRequest();
OFQueueStatisticsRequest fsr = new OFQueueStatisticsRequest();
fsr.setPortNumber(OFPort.OFPP_ALL.getValue());
req.setStatisticType(OFStatisticsType.QUEUE);
req.setStatistics(Collections.singletonList((OFStatistics)fsr));
req.setLengthU(req.getLengthU() + fsr.getLength());
try {
future = sw.getStatistics(req);
values = future.get(10, TimeUnit.SECONDS);
} catch (Exception e) {
System.err.println("Failure retrieving queues");
}
log.info("stat obtained are: " + values);
}
return values;
}
Is it this right way to get the stats from the switches? I am also
missing some jar to run this? any tips?
Thanks,
Foli
