Problem/Question

Netdata consuming high CPU after OS upgrade (>90%)

  • clearing /var/cache/netdata/* did not help.
  • systemctl stop netdata, and running the docker instance of netdata had the same performance hit.

I can’t use netdata in my production at this time as it is causing performance issues.

#uname -a

Hi, @Sean_Kennedy. Can you check which process/thread is consuming CPU resources? See how to do it using htop (search for the netdata parent process and scroll down until you see the thread with 100%).

This is in a proxmox environment - with 4 vcpus, min ram 512MB, 4GB allocated. These are light weight VMs running python containers.

Netdata doesn’t use a lot of CPU on your htop screenshots.
