Unusual Private Inbound Traffic and CPU/Disk Peak
I got a couple of 504 nginx server errors yesterday. After checking the graphs of my droplet I noticed that there is a unusual high peak in both private inbound traffic and CPU/Disk usage.
Comparing it with the last 30 days this has never happened before. So it can't be a backup process or anything.
Whats weird that its "private inbound" and not public.
I haven't made any changes to the configuration in the past 7 days. Private networking is enabled because I am running mySQL on another droplet, apart from this one that runs nginx with wordpress.
What can I do to find out whats happening?
