```hocon
monitoring: {
  webhook: {
    endpoint: "https://webhooks.acme.com/rdb-loader"
    tags: {                # Custom set of tags
      host: ${HOST}        # Environment variables are supported

                                                # Redshift role must have an access for this folder
    period: 2 hours                             # How often the check should be performed
  }
