I don't know the platform. On something un*x-like, the following should work (I assume a single logfile, without true rotation {:== writes modulo maxsize} but even that could be handled)

  • you read the file doing whatever filtering, and record size read
  • you seek to the last position recorded and filter from there
    • is there any reason why a simple scheme like this could not work? AND of course you should try what has been previously recommended
