VMware, Inc. is a leading developer of virtual machine technology. In order to diagnose software running within the virtual setting, VMware provides a script-based instrumentation technology called VProbes. However, this technology has a steep learning curve and requires the user to be familiar with the underlying system of VMware’s software. In our Clinic project we made VProbes accessible to non-programmers by exposing some of its common functionality via a web-based user interface.
