Problem with alert "Container Disk Usage" in Docker community-templates

I am installed of @russorat.

In alert “Container Disk Usage” of template is used next:

data =
from(bucket: “docker”)
|> range(start: -15m0s)
|> filter(fn: (r) => r[“_measurement”] == “docker_container_blkio”)
|> filter(fn: (r) => r[“_field”] == “usage_percent”)

Cant find for this measurement such a field.

Is it something special must be used in docker composer or in telegraf conf?

Hello @va2dim,
Have you installed telegraf?

Select the docker telegraf plugin when you set it up.

Off cause, telegraf installed and common metrcis of input docker plugin sent to influx,
but I didnt see such a field “usage_percent” under measurement “docker_container_blkio”.
