* Use relative aliases for all non-current Grafana aliases
Prevents non-latest documentation "stealing" the page away from latest
and through permanent redirects for latest pages that no longer exist.
The redirected pages are indexed by search engines but our robots.txt
forbids them crawling the non-latest page.

Alert instances
Grafana managed alerts support multi-dimensional alerting. Each alert rule can create multiple alert instances. This is exceptionally powerful if you are observing multiple series in a single expression.
Consider the following PromQL expression:
sum by(cpu) (
rate(node_cpu_seconds_total{mode!="idle"}[1m])
)
A rule using this expression will create as many alert instances as the amount of CPUs we are observing after the first evaluation, allowing a single rule to report the status of each CPU.
