We actually have to count or sum, respectively, _all_ the selected metrics for the cluster-wide view. Which means it's easiest to use the `scalar` approach after all (but only in the cluster dashboard). This still propagates all the labels. I have extended the comment for the `nodeExporterSelector` to note that the cluster dashboard only makes sense if all the selected node exporter actually belong to the same cluster. Since this is jsonnet, users can easily disable the cluster dashboard. Or even create multiple instances of the dashboards with different `nodeExporterSelector`s for different clusters.

Node Mixin
This is a work in progress. We aim for it to become a good role model for alerts and dashboards eventually, but it is not quite there yet.
The Node Mixin is a set of configurable, reusable, and extensible alerts and dashboards based on the metrics exported by the Node Exporter. The mixin creates recording and alerting rules for Prometheus and suitable dashboard descriptions for Grafana.
To use them, you need to have jsonnet (v0.13+) and jb installed. If you
have a working Go development environment, it's easiest to run the following:
$ go get github.com/google/go-jsonnet/cmd/jsonnet
$ go get github.com/jsonnet-bundler/jsonnet-bundler/cmd/jb
Note: The make targets lint and fmt need the jsonnetfmt binary, which is
currently not included in the Go implementation of jsonnet. For the time
being, you have to install the C++ version of
jsonnetfmt if you want to use make lint
or make fmt.
Next, install the dependencies by running the following command in this directory:
$ jb install
You can then build the Prometheus rules files node_alerts.yaml and
node_rules.yaml:
$ make node_alerts.yaml node_rules.yaml
You can also build a directory dashboard_out with the JSON dashboard files
for Grafana:
$ make dashboards_out
Note that some of the generated dashboards require recording rules specified in
the previously generated node_rules.yaml.
