Apologies for not getting back to you sooner. I discovered that some of my agents were sending junk data at midnight GMT. Once I solved that problem, my graphs recovered. Oddly, the graphs that were impacted were not necessarily the same graphs that had known bad data coming in at 4:00pm. I've added strict checks to all agents responsible for sending metrics, and this problem has not recurred. Logging is still an issue for me, so these patches are helpful. Thank you!
