Enable alerting high availability
You can enable [alerting high availability]({{< relref "_index.md" >}}) support by updating the Grafana configuration file. On Kubernetes, you can enable alerting high availability by updating the Kubernetes container definition.
Update Grafana configuration file
Before you begin
Since gossiping of notifications and silences uses both TCP and UDP port 9094, ensure that each Grafana instance is able to accept incoming connections on these ports.
To enable high availability support:
- In your custom configuration file ($WORKING_DIR/conf/custom.ini), go to the
[unified_alerting]section. - Set
[ha_peers]to the number of hosts for each Grafana instance in the cluster (using a format of host:port), for example,ha_peers=10.0.0.5:9094,10.0.0.6:9094,10.0.0.7:9094. You must have at least one (1) Grafana instance added to the [[ha_peer]section. - Set
[ha_listen_address]to the instance IP address using a format ofhost:port(or the Pod's IP in the case of using Kubernetes). By default, it is set to listen to all interfaces (0.0.0.0).
Update Kubernetes container definition
If you are using Kubernetes, you can expose the pod IP through an environment variable via the container definition such as:
env:
- name: POD_IP
valueFrom:
fieldRef:
fieldPath: status.podIP
