I have two HA installations. One has recently had an uptick in CPU use, 20% to 50% average CPU usage, while the other has remained relatively flat in CPU use. How can I dig into what is resulting in higher usage? I thought is had to do with the recent HAOS update but the update only impacted the usage on one of my installations so it feels like it is something else. Pointers would be appreciated.
Thanks!
Identical hardware? Take a look here GitHub - hassio-addons/addon-glances: Glances - Home Assistant Community Add-ons
The hardware and setup are similar for both, but not identical. In the past Frigate was the only thing the notable used CPU. Looking at Glances it seems like the main Home Assistant docker is using the extra resources. It started on 26 January, which I think coincides with the HAOS release.
Anyone else seeing an increase in the main docker CPU use?
I ended up recovering from a HA backup before I saw the increased CPU use. Interestingly, it wasn’t as complete of a recovery as I expected. It didn’t rollback the additional addons that I had installed, it didn’t rollback the HAOS update, and I do not appear to have lost data. Granted I could have restored to one of my VM backups, which I know would have reverted everything. On the upside, CPU use is back to normal. I am applying the outstanding updates one by one with excessive backups and trying to understand if there is anything that caused the issue.
if i remember correctly sometimes a complete machine restart helps with such.
What i know for sure - sometimes after HA update the power usage of proxmox raises and after restarting the VM its back to normal.
Thanks for the tip. I did find information about people fixing increases in CPU use of a Proxmox VM simply by rebooting. Unfortunately, that didn’t seem to help me. Even moving the VM to a different cluster node didn’t help me.
