Chapter 1. Monitoring APIs

1.1. Alertmanager [monitoring.coreos.com/v1]

Description: AlertmanagerConfig defines a namespaced AlertmanagerConfig to be aggregated across multiple namespaces configuring one Alertmanager cluster.
Type: object

Description: AlertRelabelConfig defines a set of relabel configs for alerts. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).
Type: object

Description: AlertingRule represents a set of user-defined Prometheus rule groups containing alerting rules. This resource is the supported method for cluster admins to create alerts based on metrics recorded by the platform monitoring stack in OpenShift, i.e. the Prometheus instance deployed to the openshift-monitoring namespace. You might use this to create custom alerting rules not shipped with OpenShift based on metrics from components such as the node_exporter, which provides machine-level metrics such as CPU usage, or kube-state-metrics, which provides metrics on Kubernetes usage. The API is mostly compatible with the upstream PrometheusRule type from the prometheus-operator. The primary difference being that recording rules are not allowed here — only alerting rules. For each AlertingRule resource created, a corresponding PrometheusRule will be created in the openshift-monitoring namespace. OpenShift requires admins to use the AlertingRule resource rather than the upstream type in order to allow better OpenShift specific defaulting and validation, while not modifying the upstream APIs directly. You can find upstream API documentation for PrometheusRule resources here: https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/api.md Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).
