I am installed https://github.com/influxdata/community-templates/tree/master/docker of @russorat.
In alert “Container Disk Usage” of template is used next:
|> 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?
