It would be great to be able to monitor rendering statistics such as frame render time, frame transfer time, dropped frames, etc. so we can identify any problems with a scene or its animation, and the areas where our scene is close to dropping frames.

You can have Ventuz write dropped frames to the log files by adding the option -df (for DropFrame obviously) when starting the application. Works in Designer, Presenter and Runtime. We have been using it quite a lot. But it is a chicken-and-the-egg thing. If you have the info that a dropped f rame occured written to the log file, you might get another drop frame just for that. And that could end up in a loop. Could happen. It did so a few times. Not very often but it did. I would never recommend having that run on a runtime machine. But on a Designer machine it is good to identify problems. By the way, you can also add the -ap (Append Log) option to have the log not cleared after a relaunch of Ventuz.

I think that "append log" option is -al not -ap ...
btw can someone post a list of all presenter options ?

-al : append to existing log file
-stats: show performance statistics
-kill: kill other running instance of ventuz
-df: log drop frames

You can use a script to write to the Log file yourself - anything you want! :)
Ventuz.Kernel.VLog.Info("Module Text here", "Actual message text here", Ventuz.Kernel.VPopup.Never);
You can bind a DateTime Node to the script or use the Script itself to get DateTime values and have it write whatever and whenever you want into the Log file. The example here write to the log file on the Info Level. RightClick in the Message window and select Info from the MessageLevel to see them. Per default Ventuz only displays Errors there. That setting has no effect on the log file itself.

nice, krix, but I need it in Express edition :( ... in Message window
there I can see date. You know, log file of presenter without date is almost
unusable.
