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:
promql
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.
