The FIX module shows information about FIX (Financial Information eXchange) traffic and sequence counter correctness.

Overview

Values about packets, bytes, packets per second and bytes per second of FIX traffic are shown together with a graph over time. A PCAP button allows for capturing that traffic.

A sequence counter analysis is performed. Several counters provide information about:

  • Sequence number repeated: For two subsequent FIX packets the sequence number was exactly the same.
  • Sequence number too high: Between two subsequent packets the sequence number did not increase by 1 but with a higher value. This is an indication about a packet loss.
  • Sequence number too low: Between two subsequent packets the sequence number did not increase by 1. The latter packet had a lower value.

Connections

All connections with their source and destination IPs and ports are shown. Traffic counter, counter about sequence numbers and packet loss and TCP retransmissions are shown together with history graphs. The session protocol and message types are shown per connection and can be used as a filter criteria.
