Grafana seems amazing at first.<p>Variables to abstract out some, a bit of "repeat" to loop over something, and you get pretty drop-downs that you can combine to show nice graphs.<p>Then you think "I'll add it to a playlist". and you do so.<p>Then you think "my kiosk can't scroll this much for all, let's have one screen each for the apps" and you do.<p>And then you realize you cannot use variables from playlists, and you cannot template screens.<p>So you make eight copies of your screen, one for each variable configuration.<p>And you edit each copy of your screen to set the variables, and save it.<p>And then you realize that there was a typo in one panel.<p>So you go in and edit in eight different screens to fix that typo.<p>Then you realize that it doesn't look good on the TN panel, so you need to change a few colours to get better contrast.<p>So you do that on eight different copies, by the means of clicking in every pane, navigating through the point-n-click and then pressing.<p>But you realized that you learned this, so you're fast, and use the keyboard. Except then the change doesn't take.<p>Because grafana requires you to click in another field after you've edited, or your change doesn't hold if you press "Escape" or other key to navigate back.<p>And that's how I learned how Grafana is best of breed in GUI dashboard tools. Sort of how a pug is best of breed in a dog competition.
