I’m a VPS newbie running a LEMP stack with very low traffic. I’m curious if this is a normal glitch with DO’s graph page, or where I can look at maybe a log file to understand what (if anything) happened.

Looking at the graph for my droplet I see the CPU/memory/bandwidth usage is reported each minute, but there was a break for about 21 minutes tonight where there was no reporting at all for CPU or memory and only 1 report for bandwidth usage (0/0). At the end of this blank period there was a spike of outgoing bandwidth higher than anything else today. My VPS usually averages around 0.01 Mbps outgoing but this spike was 0.54Mbps just for that one poll and then went back to normal.

I thought maybe it was DOs automated backup, but that has not happened yet.
