Dashboards & Visualizations

How to have a dashboard display an image that is being updated dynamically?

Path Finder

I have a python custom search command that generates a plot i.e. plot.png. The custom command writes the image file to the app's /appserver/static/images folder. A dashboard displays plot.png so an analyst can make changes to the custom search command's arguments. The custom search command is run again and the image file, plot.png, is overwritten in the apps static images folder. Is there a way to have the updated image display, in a production environment, without restarting Splunk and reloading the page?

@mdwecht I dont think for Production you can turn off caching. Only for Development environment you can enable web.conf config for no caching so that new static files are loaded (which again would require bump or refresh). Event after that Browser may also cache static file which may show previously loaded image instead of the new one.  https://docs.splunk.com/Documentation/Splunk/latest/AdvancedDev/CustomVizTutorial#Development_mode_s...

Can you custom command generate SVG code as search result so that you can plot image directly using SPL with Scalable Vector Graphics Custom visualization?
