High cpu usage since two weeks

Installation Home Assistant OS
1

Hello,

I use HASS.io on my NAS server (4 CPU) and sometimes the docker container with homeassistant takes 25% of CPU (so 100% of 1/4 CPU)

I’ve try to restart the docker, remove useless sensors, remove many things but I can’t avoid that.

When I listen music with MPD on the NAS the music cut because of this issue.

I don’t want to migrate my homeassistant on a raspberry pi so I want to have a solution for that.

I use:

  • Adguard
  • HACS
  • ESPHome
  • Zigbee2MQTT
  • Anniversaries
  • home-assistant-variables
  • Sonoff LAN

I use the last home-assistant update (0.108.9) but the issue is since 108 maybe.

I have disabled my “brother” printer and all configuration about brother because I read issues on it.

  • How to rollback on the last 0.107 with hass.io?

Do you have glances as an addon?

To roll back to an older install I have used the ‘SSH & Web Terminal’ add on with the command:
ha core update --version=0.107.7

Had a similar issue on my RPi3 starting with V0.108.0 but it fixed itself, kind of, with V0.108.8

Do you mean glance in the UI like that?

entities:
  - entity: light.living_room
    tap_action:
      action: toggle
  - entity: light.led_tv
    tap_action:
      action: toggle
  - entity: light.led_mirror
    tap_action:
      action: toggle
title: Salon
type: glance

You’re lucky :wink:

Thanks for the command to rollback to 0.107.7 I’ll try that.

6

Thanks for the command, I’m now back on 0.107.7 I’ll check tomorrow morning how it was with this version.

I’ve done the rollback on 0.107.7 at 22:38.

So I’ve got one cpu pick few minutes later.

I’ll post later…

Try to get a recording with py-spy https://github.com/benfred/py-spy

I meant the addon glance. I have issue with cpu with that. If i stop and start after a hassos reboot its gone.

10

Nope I haven’t this addon

11

I test it

Here the result: https://www.choiz.fr/images/profile_homeassistant.svg?123

12

My home-assistant_v2.db size is 31G…
the home-assistant_v2.db-shm size is 5.1M
the home-assistant_v2.db-wal size is 2,6G

Is it normal? How I can purge the database without loosing my config?

13

I have execute a:

recorder.purge
keep_days: 7
repack: true
14

Nothing looks out of the ordinary with the py-spy recording. Was the cpu spiking when the recording took place?

It would be helpful to see what is generating all the states and events in the database. Please check: Large homeassistant database files

15

I have remove my database now it’s about 1,6Mo :wink:

So I still have the issue

2020-04-26-131720_567x418_scrot

I launch py-spy recording at 13:14 (last 2 peaks but not reach 25% of cpu).

Here the result: https://www.choiz.fr/images/profile_homeassistant.svg

Its going to be near impossible to figure out what is going on unless you can get a capture when the issue is happening.

17

Yes I know :wink:

I try to capture when it happened but it’s difficult because it’s very random…
