<p class="MsoNormal">In the short term we are going to address some of the limitations of the interactive app batch connect plugin so that we can do more with the plugin environment. We are also going to look at providing some documentation and simple examples
of workflow/gateway style apps that do things like what you describe. I will keep you posted.<o:p></o:p></p>

still prefer a more straight forward click and go interface without the exposure to slurm submission script etc. So I'm seeing about using the interactive app form to create a job and launch it. This is basically only a small modification to the existing interactive
app scripts.<o:p></o:p></span></p>

and the chooser will list all .m files. With the markdown, I can put a link to the file explorer page as part of the page description, so users can upload their .m files to the relevant location (I've added in some Ruby that if someone visits the app page,
it creates the relevant project subdirectory etc. Given this, I can actually get away without an upload element.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:black">You can include standard HTML in the help sections of the “attributes” in the form.yml.erb. The “attributes” have a key “widget” that specifies the Rails form helper method to execute to create the associated form
element (<a href="http://guides.rubyonrails.org/v4.2/action_view_overview.html#formhelper" target="_blank">http://guides.rubyonrails.org/v4.2/action_view_overview.html#formhelper</a>). The help text actually is rendered using a markdown parser that is set
to allow HTML tags. So you may or may not be able to hack in there script tags with embedded JavaScript that could manipulate the DOM however you see fit, though that would be quite a hack. There isn’t a way right now to put arbitrary HTML as far as I know.
I look a little more and if I find something I’ll let you know.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">What file chooser are you using (or wanting to use) for choosing existing files on the cluster?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">In regards to being able to do file uploads, unfortunately it appears there is a bug in the code where the value of all of the attributes are coerced into strings prior to being used to render the template files.
So you can add a file upload form element but won’t be able to process it. I was able to get file uploading working with hack. Though it is unreliable and something that is likely to break in future versions of OnDemand without warning. I can share that if
you would like.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:black">No thought has been given to making this app working outside of OSC or with something other than moab and ganglia, which is why it was never advertised as an Open OnDemand app. If you have success running then
that will be helpful to know and we can consider including this as an optional installable app in the stable rpms folder and mention it in the documentation. Note that an updated version of this simple app will be available this week that has a much simpler
code base, similar to the tutorial app <a href="https://osc.github.io/ood-documentation/master/app-development/tutorials-passenger-apps/ps-to-quota.html" target="_blank">

<p class="MsoNormal"><span style="color:black"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">As for getting this and the Ganglia graphs in Active Jobs to work, at OSC we depend on the same ganglia config section in the “custom” section above. That would need to exist and be properly set in order to work.
I will say in both cases I would consider this feature “experimental”. It is reliable enough to work at OSC that we use it in production, but we are just making use of the query param “api” exposed by Ganglia’s graph.php script that generates the graph images,
instead of using a supported API provided by Ganglia or reading the RRD itself.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">In regards to file uploads or file selection in an interactive app, we have not tried or demonstrated that yet, so I don’t know. I can look into it and follow up this week on this thread.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:black">Hi All,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">I’ve just started playing with OOD in a VM environment, just to get a feel for how it works and how it could benefit our HPC user community. It does look like it could be a really useful tool (great work by those
involved!) but I just have a few questions, the first two regarding differences between my initial setup and what appears on the various video/presentation versions –

<ol style="margin-top:0in" start="1" type="1">
<li class="MsoNormal" style="color:black;mso-list:l0 level1 lfo1">I can’t seem to find the “System Status” app on the couple of simple installations I’ve done (btw my install is ondemand-1.3.7-1.el7.x86_64, ondemand-release-web-1.3-1.el7.noarch)<o:p></o:p></li><li class="MsoNormal" style="color:black;mso-list:l0 level1 lfo1">This may be a simple one, but how do you integrate ganglia rrd graphs into the active job display?
<o:p></o:p></li><li class="MsoNormal" style="color:black;mso-list:l0 level1 lfo1">Finally, has anyone got any advice/examples of including ‘widgets’ like file uploads or file selection in an interactive app? While the job composer is really great for the majority, I’d like
to make a very simple job submission entry point based on the interactive app setup. Most of it is there, bar the option to select an input file etc.<o:p></o:p></li></ol>
<p class="MsoNormal"><span style="color:black"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">Sorry for the very simple questions or if I’ve missed something obvious here, I have tried going through the documentation<o:p></o:p></span></p>
