Checking an alert notification configuration

You learn how to ensure your alert notification configuration is in effect. You fetch the configuration directly from the alertmanager and check that it is reachable.

  1. Port-forward the prometheus service.
    $ kubectl \
        -n istio-system \
        port-forward \
        service/prometheus \
        9093:9093
  2. From another terminal the configuration is reachable by using the following curl command.
    $ curl http://localhost:9093/api/v2/stat
  3. Check that the output shows your configuration.
    Alternatively, to check the output, you can use the alertmanager WebUI by navigating to http://localhost:9093/#/status.
