@kylebrandt @marefr what do you think about giving panics a higher logging level? I understand that crashy plugins could cause problems, but catching panics is extremely valuable in production environments and debug logging often isn't turned on.
If we're worried about a ton of noise here, maybe Grafana itself could expose some kind of logEvery handler that would log only 1/10 panics or something similar.
