Network Package

The network package groups several backends together for convenience.  All of the backends in this package collect statistics related to network loading.

The data collected by these backends can be very helpful when doing network planning.   For example, if you were planning to partition your network, this package could provide you with a great deal of information about which machines are communicating.

Backends

  • tcp - This histogram backend counts the number of TCP sessions that it sees.  It records:
    • source host
    • destination host
  • tcppackets - This histogram backend counds the number of TCP packets that it sees and sums the packet sizes, giving you an estimate of traffic volume on your network.  It records:
    • source host
    • source port
    • destination host
    • destination port
  • udp - This histogram backend counts UDP packets.  This backend can be useful in determining if all of your UDP traffic is related to DNS, or some other application.  It records:
    • source host
    • source port
    • destination host
    • destination port
