FIXtail

FIXtail is a modified version of GNU Tail, with extra features targeted primarily (though not exclusively) at bandwidth and latency Analysis of Financial Information eXchange (FIX) log files. In addition to all the usual features of GNU tail, like following multiple files by name or file descriptor, FIXtail supports filtering by timestamp, by certain FIX field values or by regular expression, and can generate periodic reports of bytes, bits, or lines per second over specified time intervals.
