get_after(timestamp, s=None)[source]

Find all the (available) logs that are after the given time stamp. Override this function in class LogFileOutput.

Parameters
  • timestamp (datetime.datetime) -- lines before this time are ignored.

  • s (str or list) -- one or more strings to search for. If not supplied, all available lines are searched.

Yields

(dict) -- the parsed data of lines with timestamps after this date in the same format they were supplied.
