My team is developing a web application that takes a few user inputs, and then based on those inputs modifies an OpenStudio model through ruby measures, runs the OpenStudio model, and then reports the outputs. We are using ASP.NET to develop the web app (as a team member has extensive experience in this language, and none in Ruby on Rails), however, whenever we attempt to run a ruby measure remotely through the web app it never runs the ruby script. What is extremely peculiar is that the web app does run the ruby script when it is run on the local host. We are at a loss for what could be causing this failure when running remotely, and have spent a significant amount of time already trying to debug to no avail. Any idea what the problem might be, or have seen any documented cases of running a ruby script through a web app? Thanks in advance for any insights.

Have you resolved this yet?

Are you trying to use the C# bindings to OpenStudio? Or are you running OpenStudio measures via a system call?

Dan's comment is valid around checking the log files. I would also check security settings. Are you using IIS? If so you will probably have to allow IUSR access to the run directories for the measures and probably OpenStudio.

We are running via a system call, and we did solve it, see my answer below

There were two main issues that were resolved in order to fix the OpenStudio and Ruby remote server bug. The first one was that the path name to the ruby files could not contain any spaces, so any spaces found had to be replaced with underscores. This resolved the issue of calling the Ruby code but did not resolve fully executing the code. This was solved by integrating the setup files of Ruby, OpenStudio and Energyplus with ASP. doesn’t have proper permission to access files outside the application folder.

The VirtualPulse project has made a similar web application that runs measures, though they are not using ASP.NET. I can't really comment on why your system isn't working, it's possible some additional security settings are enabled in the production environment? You should look through your log files and see what you can find.

You may want to consider using our framework for large scale anaylsis, even if you are doing smaller runs. You can setup vagrant on your server instead of relying on third party hosting from Amazon.

I have an example programmatic modeling repository setup that uses a ruby rake task to generate the analysis json instead of an Excel spreadsheet. I use this approach for integration testing of a string of measures (more robust than the basic test that comes with each measure).

Here is a link to one of the example workflows. You could gather user input via a web interface to populate this.

Back to your specific issue, are you getting a specific ruby error, like the measure not finding OpenStudio?
