Asset registration

Sensu Assets are the best way to make use of this plugin. If you're not using an asset, please
consider doing so! If you're using sensuctl 5.13 with Sensu Backend 5.13 or later, you can use the
following command to add the asset:

sensuctl asset add betorvs/sensu-alertmanager-events

If you're using an earlier version of sensuctl, you can find the asset on the [Bonsai Asset Index][].

Check definition

Maybe you need to add extra flags if you want to use --auto-close-sensu.

type: CheckConfig
api_version: core/v2
  name: sensu-alertmanager-events
  namespace: default
  command: sensu-alertmanager-events -e ""
  - k8s-agents
  - betorvs/sensu-alertmanager-events


If you run these check in more than one cluster and use the same Sensu Namespace, use this flag:
--auto-close-sensu-label "{\"cluster\":\"\"}".
