Weird spikey CPU load curve over 90 minutes
Yesterday, I found my Asterisk server was getting hammered by someone trying to hack their way in. So I closed of ALL ports except ssh for my IP, and the IP of the server I peer too. Instant load reduction, all good.
But this afternoon, I noticed this very weirdly shaped CPU load graph - I don’t think it’s incoming packets getting blocked, otherwise the network traffic would be increased too, correct?
I checked all the logs - no logins, nothing in the error log… I’m baffled by the shape of it too! Screenshot: https://www.dropbox.com/s/5g8kl6nm95x1tqv/ScreenClip%20%5B6%5D.png?dl=0
