Lorna Mitchell has a new post today showing you how you can use XHGui in a virtual machine, sorting the resulting performance data on the VM rather than your local machine.

I'm doing some performance tuning on a project at the moment and my favourite tool is still XHGui - but it's designed to run on the same machine as its victim and since this is a vagrant VM, the chances of me destroying the machine and therefore the data are pretty high! Instead, I set it up to store the data onto the host and I thought I'd share how I did that. All these instructions for Ubuntu on both host and guest, and I've tried not to be specific about the vagrant elements in order to focus on how the pieces fit together rather than what you should type.

She walks you through all the steps you'll need to get the software up and running as well as configuring the actual guest VM to direct the data to the right place. She sets up the data source to push the results into (a MongoDB) and configures the PHP installation with an "auto prepend" of the XHGui header file. Finally, she includes the commands you'll need to view the data on the VM itself, running the built-in PHP web server as an ad-hoc instance on the VM itself.
