Monitoring a Customized Windchill Environment
You can use the System Monitor to monitor and troubleshoot your customized Windchill environment. Depending on where the custom code is, you may be able to use the System Monitor without any modifications to collect information from your custom code. If the out-of-the-box configuration does not collect all of the information you would like to see, you can add sensors to key custom classes to collect the data.
* 
Be careful when adding sensors as they can have an impact on performance. Consequently, you should ensure that you have performance measures that you can reliably use to verify performance before and after adding sensors.
Additionally, validate all changes made to the System Monitor System Profile against your development environment before deploying the changes into your production environment.
