Unreliable InfluxDB size sensor

Configuration
12

Some progress.

This works in the influx container:

du -s /data/influxdb/data/homeassistant

It gives me a nice machine readable number of KB (no unit as occurs with the human readable -h option).

According to portainer the container name is

addon_a0d7b954_influxdb

However running this from the CLI

bash docker exec addon_a0d7b954_influxdb du -s /data/influxdb/data/homeassistant

Gives me a bunch of command not found errors. So it was more than a bit doubtful that this would work:

- platform: command_line
  name: InfluxDB Size Test
  command: "bash docker exec addon_a0d7b954_influxdb du -s /data/influxdb/data/homeassistant"
  unit_of_measurement: "MB"
  value_template: '{{ value / 1024 }}'

And as expected, it does not.

Command failed: bash docker exec addon_a0d7b954_influxdb du -s /data/influxdb/data/homeassistant
