I have setup a monitoring schema using netdata to prometheus to grafana

Evething works ok, but I have a metric that I cant seem to create a querry for that grafana will respond to.
netdata_cgroup_cpu_percent_average selected in prometheus graph produces a graph in using the following many containers installed on the server - ( at least 20 )

I can’t seem to construct a grafana query that will graph anything at all?

netdata_cgroup_cpu_percent_average is selected for the prometheus dropdown metric in the graph function of prometheus.

netdata_cgroup_cpu_percent_average{chart=“cgroup_kubepods_burstable_podf575902c_6f32_11e8_bbe0_005056806200.cpu”,dimension=“user”,family=“cpu”,instance=“dcmidavgie0775”,job=“netdata-scrape”}

is one of many items on the graph created

what would a grafana metric for prometheus look like? Nothing I’ve tried to date has worked.
