+The following is completely optional, it will enable Prometheus to generate alerts from some Netdata sources. Tweak the
values to your own needs. We will use the following `nodes.yml` file below. Save it at `/opt/prometheus/nodes.yml`, and
add a _- "nodes.yml"_ entry under the _rule_files:_ section in the example prometheus.yml file above.
