negative values with irate for CPU usage

[enutrofff]

Hi All,

I use this query to get the CPU utilization:

100 - (irate(node_cpu{mode="idle", instance=~"Web:9100"}[5m])) * 100

With this query, I got negative values in my graphs

scrape_interval for this metric is: 15s

Please find below the raw values and timestamps around the artifact:

cpu_minus.zip

I'm using Prometheus version: 2.0.0-rc.1

why is this happening?

It makes more sense to ask questions like this on the prometheus-users mailing list rather than in a GitHub issue. On the mailing list, more people are available to potentially respond to your question, and the whole community can benefit from the answers provided.
