About Prometheus Alertmanager
Alertmanager 0.35 adds a gRPC API and a new UI, and breaks event recorder configs
Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.35.0 (November 9) is the largest release in the feed: an experimental ConnectRPC API (Connect, gRPC and gRPC-Web) beside api/v2, a new Mantine UI at /ui/, Slack thread replies for alert updates, and breaking changes that require named event recorder outputs, move its output to an events/v2 schema and promote auto-gomemlimit to a plain flag. It follows 0.34.2, which turned CORS off by default.
