It depends on what kind of data you're wanting to see in the log file. If you're just wanting to see how many times something has been executed you could set up java.io in your data cube and write to a log file for each method of the datacube or your dataset. fiddler2 is also a good tool that I've used to see the traffic a report creates.<br />
<br />
You could use some code like this<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
importPackage(Packages.java.io);

file = new File("C:\\Users\\kclark\\Desktop\\mylog.txt");

if (!file.exists()) {
file.createNewFile();
}

fw = new FileWriter(file.getAbsoluteFile());
bw = new BufferedWriter(fw);
bw.write("onFetch() dataset");
bw.close();
</pre>
<br />
I placed this in the onFetch() of my data set.
