Capture options

Discard old data under memory pressure. (If you capture all events for a long time, it is possible to exhaust memory and crash. Throwing out older data avoids this problem.)

Include the actual bytes sent/received. (This will result in huge log files, and can expose sensitive data)

• TIP: logging from the command line.
  Another way to capture network events is by using the command line flag:

  --log-net-log=FILENAME [ --net-log-level=NUMBER ]

  This will stream the network events directly to a file of your choosing. If you additionally want it to log the network bytes, then pass --net-log-level=0.
