Hi Pat,

I’m running a note.js agent on Ubuntu Linux and it’s able to proccess the jobs and run the tests but the raw page data and the screenshots are empty.
Could you help me? Thanks!

The output of node.js is:

Running the Node.js agent on CentOS 6 I get the screenshots and the HAR data, but the CSV data stay empty. Would it be a bug? Anyone here is using Node.js?

Thank you!

Sorry, the csv data isn’t created by the server in the case of the NodeJS agents right now. It shouldn’t be too hard to create, it’s just a passthrough of the raw agent data for the existing windows agents and would just need to be generated on the fly. All of the same data should be available in the json and XML interfaces if you’re scripting it.

I created an issue to generate the csv’s on-demand for the agents that don’t currently report it: CSV data not available for non-windows agents · Issue #104 · WPO-Foundation/webpagetest · GitHub

Thanks Pat! Screenshots and XML interface is enough for me now.
