Description

Network Costs Metrics Grafana dashboard has incorrect query for Cross Region Data and Cross Zone Data panels have incorrect label names in queries.

Both panels are built using kubecost_pod_network_ingress_bytes_total metric as below:

Cross Region Data:

sum(increase(kubecost_pod_network_ingress_bytes_total
    {internet="false",namespace=~"$namespace",cluster_id=~"$cluster",pod_name=~"$pod_name", sameRegion="false",sameZone="false", service=~"$service"}
    [1h]))
by($aggregation)

Cross Zone Data:

sum(increase(kubecost_pod_network_ingress_bytes_total
  {internet="false", namespace=~"$namespace", cluster_id=~"$cluster", pod_name=~"$pod_name", sameRegion="true", sameZone="false", service=~"$service"}
  [1h]))
by($aggregation)

However, these queries have following typos:

• kubecost_pod_network_ingress_bytes_total metric has no labels such as sameZone and sameRegion, but rather same_zone and same_region;
• Also service label is not always available, so should be keep it in this dashboard? Or maybe metric has to be fixed with default value for this label?

Example metric from Kubecost Prometheus

If you agree that it is an issue, I am happy to work on fix :)

Steps to reproduce

1. Deploy Kubecost with Network Costs Monitoring enabled
2. Enable Grafana and deploy dashboards
3. Check Network Costs Metrics Dashboard -> Cross Region Data or Cross Zone Data panels.

Expected behavior

These panels should show actual data
