Questions/Comments re CSV file #45

Open rfajman opened 3 years ago

rfajman commented 3 years ago

Just a few questions/comments about the CSV file. I hope they aren't too redundant.

  1. What is Index?
  2. What are the units of Time (U)?
  3. I assume that Time (S) is the beginning of the interval.
  4. Is Speed(B) the total number of bytes transfered in the interval? To me, B means bytes and b means bits. Is that true here?
  5. In Speed(S) assume that 10.476 mb, for example, is megabits/second.
  6. In Message, I assume that Error means that there was a problem connecting to the server's URL or some error during the connection.
  7. In Message and Status, does Offline mean that the SpeedTestLogger was not running or that the network connection was down? I'm guessing that SpeedTestLogger being down results in missing rows in the CSV file and Offline mean that the network connection was not available.
  8. I assume that IP Changed refers to my External IP Address.

I'd appreciate any help any one can give me.

I've figured out a lot of this myself:

  1. Time (U) is seconds since the beginning of some epoch. Which one doesn't really matter.
  2. Speed (B) is the number of bytes transfers in the interval.
  3. Speed (S) is Speed (B) times 8 and divided by the length of the interval in seconds and given the units of mb/s.
  4. I think that Offline means that the logger was running, but could not collect any data. I'm not sure what it means when Offline is listed twice (in Message and Status).
  5. I still don't know what Index is.

Any comments or help on the remaining questions would be appreciated.
