Querying Prometheus form Grafana dashboard.

[zo...@dojesta.com]

Hi All,

I have just installed Prometheus info below and Grafana on the same host.

I have configured 2 targets  one is Docker using cAdvisor the second is the local host.

Grafana was installed and configured and managing collecting data from other sources and i have imported several dashboard to present the Prometheus info.

However I am missing something and I will appreciate any help.

The Grafana dashboard is still empty showing "no data point" for example in one of the dashboard.

For example in a graph for metric lookup for " container_cpu_user_seconds_total" i can get the info from the Prometheus console.

But the dashboard graph for the query sort_desc(sum(rate(container_cpu_user_seconds_total{image!=""}[1m])) by (name)) return no data also from the Prometheus console.

What am I am missing in the configuration or did I missed something in the installation.

Any information suggestion will be highly appreciated.

Thanks,

Zohar.

Hi mate,

Check if you have added the data source in grafana.

Thanks,

Thanks that issue is not with Grafana since I can't get the information from the Prometheus graph console itself.

For example I am collecting data from a docker host using cAdvisor and I can see from the Prometheus graph console that:

container_cpu_user_seconds_total is been collected.

But when I am executing more complex query like sort_desc(sum(rate(container_cpu_user_seconds_total{image!=""}[1m])) by (name)) from the Prometheus console I get "no data" in response.

What am I missing here?

I will appreciate any help.

Best,

Zohar.

The open question remain why "container_cpu_user_seconds_total" is available on the Prometheus console but the query sort_desc(sum(rate(container_cpu_user_seconds_total{image!=""}[1m])) by (name)) returns w/out data.

Any idea?

Will appreciate any help.
