Find all the (available) logs that are after the given time stamp.
If s is not supplied, then all lines are used. Otherwise, only the lines contain the s are used. s can be either a single string or a strings list. For list, all keywords in the list must be found in the line.
The time stamp is the floating point number of seconds after the boot time, and is not related to an actual datetime. If a time stamp is not found on the line between square brackets, then it is treated as a continuation of the previous line and is only included if the previous line’s timestamp is greater than the timestamp given. Because continuation lines are only included if a previous line has matched, this means that searching in logs that do not have a time stamp produces no lines.
- timestamp (float) -- log lines after this time are returned.
- s (str or list) -- one or more strings to search for. If not supplied, all available lines are searched.
Log lines with time stamps after the given time.
timestampshould be in float type, otherwise a TypeError will be raised.
Parameters: prefix (str) -- The prefix of the line to look for. Ignores any timestamp before the message body. Returns: Does any line start with the given prefix? Return type: (bool)
Parameters: prefix (str) -- The prefix of the line to look for. Ignores any timestamp. Returns: All logs start with the given prefix without timestamp. Return type: (list)
