Notification Policies
Notification policies provide you with a flexible way of designing how to handle notifications and minimize alert noise. For a complete explanation on notification policies, see the upstream Grafana documentation.
Tip
If you already know which contact point an alert should send to, you can directly set thereceivers property on the alert rule.Simple Notification Policy
The following snippet shows an example notification policy routing to the operations or security team based on the team label.
apiVersion: grafana.integreatly.org/v1beta1
kind: GrafanaNotificationPolicy
metadata:
name: grafananotificationpolicy-sample
spec:
instanceSelector:
matchLabels:
dashboards: "grafana"
route:
receiver: grafana-email-default
group_by:
- grafana_folder
- alertname
routes:
- receiver: grafana-email-operations
object_matchers:
- - team
- =
- operations
- receiver: grafana-email-security
object_matchers:
- - team
- =
- security
Dynamic Notification Policy Routes
There might be scenarios where you can not define the entire notification policy in a single place and you have to assemble it from multiple resouces.
In this case, you can use the routeSelector field in combination with multiple GrafanaNotificationPolicyRoute resources.
Both GrafanaNotificationPolicy and GrafanaNotificationPolicyRoute objects support the routeSelector field.
All GrafanaNotificationPolicyRoute resources will then be discovered based on the label selector defined in spec.route.routeSelector.
In case spec.allowCrossNamespaceImport is enabled, matching routes will be fetched from all namespaces.
Otherwise only routes from the same namespace as the GrafanaNotificationPolicy will be discovered.
The discovered routes are then used when applying the notification policy.
Note
Thespec.route.routes and spec.route.routeSelector fields are mutually exclusive.
When both fields are specified, the routeSelector takes precedence and overrides anything defined in routes.The following shows an example of how dynamic routes will get merged.
apiVersion: grafana.integreatly.org/v1beta1
kind: GrafanaNotificationPolicy
metadata:
name: grafananotificationpolicy-sample
spec:
allowCrossNamespaceImport: true
instanceSelector:
matchLabels:
dashboards: "grafana"
route:
receiver: grafana-default-email
group_by:
- grafana_folder
- alertname
routes:
- receiver: grafana-default-email
object_matchers:
- - team
- =
- a
- - inline
- =
- first
routeSelector:
matchLabels:
team-a: "child"
- receiver: grafana-default-email
object_matchers:
- - team
- =
- b
- - inline
- =
- second

apiVersion: grafana.integreatly.org/v1beta1
kind: GrafanaNotificationPolicyRoute
metadata:
name: dynamic-c
namespace: grafana-crds
labels:
team-a: "child"
spec:
receiver: grafana-default-email
object_matchers:
- - crossNamespace
- =
- "true"
- - dynamic
- =
- c
routeSelector:
matchLabels:
team-c: "child"
---
apiVersion: grafana.integreatly.org/v1beta1
kind: GrafanaNotificationPolicyRoute
metadata:
name: dynamic-d
labels:
team-c: "child"
spec:
receiver: grafana-default-email
object_matchers:
- - dynamic
- =
- d
---
apiVersion: grafana.integreatly.org/v1beta1
kind: GrafanaNotificationPolicyRoute
metadata:
name: dynamic-e
labels:
team-a: "child"
spec:
receiver: grafana-default-email
object_matchers:
- - dynamic
- =
- e
The resulting Notification Policy will be the following:
