Empty graphs in USE Method dashboards

[serathius]

All graphs beside Disk Utilization are empty.
Looks like queries using group_left are all returning no results.
Example:

record: node:node_cpu_utilisation:avg1m
expr: 1
  - avg by(node) (rate(node_cpu{job="node-exporter",mode="idle"}[1m])
  * on(namespace, pod) group_left(node) node_namespace_pod:kube_pod_info:)

[serathius]

Both subqueries return results
rate(node_cpu{job="node-exporter",mode="idle"}[1m]) returns results labeled by node
node_namespace_pod:kube_pod_info: labeled by namespace, pod, node
I don't understand prometheus m-on-m queries to well but everythink looks correct.

Is there any label missing?

Based on #30 I checked node_exporter version, but I'm using 0.15.2

(Not sure which issue we're using.)

There's data if the window is changed to [5m]. See #30 (comment)

Ok, I lets move rest of discussion there.
