Alerts for experiment metrics, alerts for BBE, bugfix in 1 dashboard
The bulk of this release is new Prometheus alerts. We now have alerting for:
- blackbox_exporter metrics that mlab-ns now relies on.
- alerts for the blackbox_exporter instances themselves.
- alerts for a new instance of node_exporter than is running on eb.measurementlab.net
Additionally this release contains:
- A new Prometheus scrape job which will scrape a node_exporter instance on EB.
- A bugfix to the Ops_PlatformOverview Grafana dashboard.
