I have a python custom search command that generates a dendrogram plot file i.e. dendrogram.png. The custom command writes the image file to the app's /appserver/static/images folder. A dashboard displays dendrogram.png so an analyst can make changes to the custom search command's arguments. When the custom search command is run again and the image file, dendrogram.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?
