Hi Warren,

if you post a link to the log file I can process the logs for you. As far as I am concerned they carry no sensitive information (I happily share mine) but have a look inside before posting a link to convince yourself that this is OK.

	Sorry, I use matlab at work and it is the only think I am reasonably proficient in, and octave is freely available hence my choice...

	Yes, that is something to run on some other place, hence the ssh examples how to harvest the log files from the router from a different machine.

	On my mac (Monterey, intel cpu) I installed octave via homebrew resulting in version 7.2 which is what I use to test... but the plotting code does not do anything earth shattering anyway, so feel free to use your toolkit of choice.
