I had performance issues as posted here which showed as high CPU loads. These where caused by IO_Waits. Not something you might expect when using an SSD, but perhaps worth to monitor for a while.

I used a command line sensor since it is not by default available. You can create the sensor by adding the code below to your configuration.yaml

command_line:
  - sensor:
      name: CPU IO Wait
      command: top -b -n1 | grep ^CPU | awk '{printf("%.0f"), $10}'
      scan_interval: 3
      unit_of_measurement: "%"
      value_template: '{{ value }}'

As you can see in the topic, it showed a direct relation with the CPU loads.

Edit: Since 2023.6 the command line sensor syntax has changed. This edit on June 8 '23 replaces the old YAML.
