InfoInhibitor #
Meaning #
This is an alert that is used to inhibit info alerts.
By themselves, the info-level alerts are sometimes very noisy, but they are relevant when combined with other alerts.
Full context
More information about the alert and design considerations can be found in a kube-prometheus issue
Impact #
Alert does not have any impact and it is used only as a workaround to a missing feature in alertmanager.
Diagnosis #
This alert fires whenever there’s a severity="info" alert,
and stops firing when another alert with severity of warning or
critical starts firing on the same namespace.
Mitigation #
This alert should be routed to a null receiver and configured to inhibit
alerts with severity="info". Such configuration is available at https://github.com/prometheus-operator/kube-prometheus/blob/main/manifests/alertmanager-secret.yaml
