To log the engine's operations edit the engine's application.config file (in ...\Program Files\Metastorm\BPM\Engine) and add the following key to the appsettings section:
<appSettings>
...
<add key="OperationLogLocation" value="c:\logs"/>
</appSettings>
Restart the engine to start logging (the folder referenced in the key you just added must already exist when the engine restarts or logging will not be enabled, the engine will not create the folder itself)
Note: Remember to switch off the logging when you are done!
