I am using Ubuntu 18.04 on a digitalocean droplet.

Here you can see the DigitalOcean bandwidth monitor graph

As you can see in the image the spikes occur exactly once every hour. According to the digitalocean monitor they start at hour:50minutes and they stop at nextHour:10minutes the peak being at hour:00 minutes.

I am new to ubuntu and I don't know how to find out what is causing those spikes.Please help :D.
