When monitoring the state of a system, it is convenient to have
the data available at a constant time interval. Unfortunately,
you may not always be able to fetch data at exactly the time
- you want to. Therefore R\bRR\bRD\bDt\bto\boo\bol\bl lets you update the logfile at
+ you want to. Therefore R\bRR\bRD\bDt\bto\boo\bol\bl lets you update the log file at
any time you want. It will automatically interpolate the value
of the data-source (D\bDS\bS) at the latest official time-slot
(interval) and write this interpolated value to the log. The
N\bNO\bOT\bTE\bE:\b: that there is no authentication with this feature! Do not setup
such a port unless you are sure what you are doing.
