That changes today with the introduction of instrument/dashboard templates! Templates permit you to leave the source unspecified, and later dynamically toggle the source being visualized. To create an instrument template, simply add a stream to an instrument and use the percent sign (%) as the source. While inspecting an instrument template, a form on the left enables you to toggle between different sources, including wildcards. Try it out!
Now that you can construct instrument templates, once you add them to a dashboard an input field next to the date-picker enables you to dynamically toggle all the templates in said dashboard to the source of your choosing:
Much like our date-range query parameter support, we use HTML5's replaceState support to dynamically update the source query parameter in your address bar as you toggle a template between different sources. You can bookmark or copy/paste the URI with the source query parameter set and the instrument/dashboard template will load with that source the next time you go to that URI:
We expect this to significantly improve your experience while monitoring larger scale infrastructure, and as always any feedback you might have is invaluable. Enjoy!
