I have a website (it’s the only site hosted on the droplet) and sometimes (about 1 time each month, but not on the same day) the CPU usage goes through the roof. I have absolutely no idea what’s causing it, but in 1 minute the CPU usage goes from 5-13% straight to 100% causing the server to hang.
Disk I/0 also peaks and memory usage goes from 30% to 70%.
I have checked Google Analytics to check if there is a sudden increase in visitors as my client thought this happened after posting an instagram story. However, the largest visitors at the same time is only 15 which is unlikely to cause this.
I have no clue where to start looking what might be causing these issues. Any hints?
