Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set will cover all product layers, including MOSK management (formerly MCC). This means everything you need will be in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Replaced with RedisClusterTargetDown in 23.3

Severity	Major
Summary	Redis cluster Prometheus targets outage.
Description	Prometheus fails to scrape metrics from 2/3 of the `{{ $labels.cluster }}` cluster endpoints (more than 1/10 failed scrapes).

RedisDisconnectedReplicas¶

Severity	Warning
Summary	Redis has disconnected replicas.
Description	The `{{ $labels.cluster }}` Redis cluster in the `{{ $labels.namespace }}` namespace is not replicating to all replicas. Consider verifying the Redis replication status.

RedisDown¶

Severity	Critical
