These nested policies should route alert instances where the region label is either us-west or us-east. Only the us-west region team should receive grouped alert notifications.
{{< admonition type="note" >}}
In Grafana, each label within a notification policy must have a unique key. If you attempt to add the same label key (e.g., region) with different values (us-west and us-east), only the last entry is saved, and the previous one is discarded. This is because labels are stored as associative arrays (maps), where each key must be unique.
For identical label keys use regex matchers (e.g., _region=~"us-west|us-east"_).
Label matchers are combined using the `AND` logical operator. This means that all matchers must be satisfied for a rule to be linked to a policy. If you attempt to use the same label key (e.g., region) with different values (e.g., us-west and us-east), the condition will not match, because it is logically impossible for a single key to have multiple values simultaneously.
However, `region!=us-east && region=!us-west` can match. For example, it would match a label set where `region=eu-central`.
Alternatively, for identical label keys use regular expression matchers (e.g., `region=~us-west|us-east`).
