Not sure if this works with a recent femon, but if it doesn't you should be able to make some changes to my method to make it work. Here's the trick: 1. Tune to whatever you want to measure. 2. Execute in a terminal: "femon -h -c 3600 > filename.signal". 3600 is for one hour, if you want to test for e.g. 10 hours enter 36000. The resulting file will usually be under 5MB so don't worry. Good advice: put the current time in the filename because brains are unreliable. 3. That's quite a bit to read. But we can do it faster: Total amount of errors: "cat filename.signal | grep -c unc[^\s][^0]". You might need to change the regex for other femon versions. All errors and when they occured: "cat filename.signal | grep -n unc[^\s][^0]". -n will make it show line numbers. If the first error, for example, is on line 1800 that means the first error occured half an hour after the start of the measurement. Hope this helps.
