Detailed Description

Generate periodic packet statistics.

This module will periodically generate statistics concerning the traversing packets. The statistics are emitted as Boost.Signals signals:

  • signals.packetsPerSecond: number of packets in the last interval scaled to 1 second
  • signals.bytesPerSecond; number of bytes in the last interval scaled to 1 second
  • signals.bytesPerPacket: minimal, average and maximal packet size in the last interval
These signals are normally connected as needed to senf::Statistics instances. 
senf::RateAnalyzer analyzer;
senf::Statistics packets;
senf::Statistics packetSize;

analyzer.signals.packetsPerSecond.connect(packets);
analyzer.signals.bytesPerPacket.connect(packetSize);

analyzer.startStatistics(senf::ClockService::milliseconds(100u));

Statistics output is only generated after a call to startStatistics()
