-- Tests an alarm by displaying a banner on the Amazon Lightsail console.
-- If a notification trigger is configured for the specified alarm, the
-- test also sends a notification to the notification protocol (@Email@
-- and\/or @SMS@) configured for the alarm.
--
-- An alarm is used to monitor a single metric for one of your resources.
-- When a metric condition is met, the alarm can notify you by email, SMS
-- text message, and a banner displayed on the Amazon Lightsail console.
-- For more information, see
-- <https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-alarms Alarms in Amazon Lightsail>.
