Blank droplet - CPU spike every hour, Disk I/O spike

Posted July 3, 2020 199 views
CentOSCentOS 8

Hi, I am new to DO. I have recently just set up a basic droplet for $5 and only have CentOS 8 installed. I have not even changed the root password yet, that’s how fresh the droplet is.

So upon checking the droplets graph I notice there is a spike 30 seconds before every hour? The CPU spikes along with the load and Disk I/O.

Why does this happen when I have done nothing yet on the droplet?

Please see screenshot here

Hi there @Kay86,

This is quite interesting, I’ve created a new fresh CentOS 8 Droplet and install the DigitalOcean monitoring agent to see if I can replicate that behavior. I will let it run for a few hours and update you once I have some more data in the graphs.

What is the region that you’ve deployed the Droplet at?

Also do you have any Cron jobs at the moment? You can check that with:

  • crontab -l

Did you also use any of the images from the DigitalOcean Marketplace, or was it just the default CentOS 8 Droplet?

Regards,
Bobby

    Hi there,

    My blank CentOS 8 Droplet, has been running for the past 4 hours but I’ve not noticed any spikes at all.

    I could suggest setting up a cron job to note down your process list at the exact same time the CPU spikes occur to log down the processes and track down the one that could be causing the spike.

    Let me know how it goes!
    Regards,
    Bobby
