Here is an example of a configuration file and four files generated from it. Notice that the files press.txt and tanks.txt have empty data points in them. This is because the collect command specified a global default of any. The other two files show the effects of collect using all and fill.

The first line in each output file shows the values of all the requested points before the Cascade TextLogger was started, at the time of the most recent change.
