Graph legends have irrational behavior when monitoring thousands of hosts

[e271828-]

Prometheus graphs are largely unusable when looking at properties across many thousands of hosts.

The graph itself has reasonable behavior, but the legend extends infinitely instead of enforcing a maximum visible length and hiding the rest behind a folded div.

The expression browser is only intended for ad-hoc debugging and exploration, for general dashboarding use we recommend Grafana.

Also, it's generally unwise to have thousands of plots on a single graph. It's extremely difficult for a human to pick anything useful out of that much noise.

Ad-hoc debugging and exploration is less than convenient when you can't stack two graphs on top of each other due to the size of the legends :)

From practical experience I must say I disagree strongly with your second point.

I'm afraid I don't think it's practical to fix this on our end.
