Sets up a CloudWatch Alarm that triggers if the Lambda fails invocations. This usually happens from uncaught exceptions in the lambda.
Optionalprops: { appendToAlarmDescription?: string }Configuration for an alarm.
OptionalappendToAlarmDescription?: stringAdd extra information to the alarm description, like Runbook URL or steps to triage.
Returns a string representation of this construct.
StaticisChecks if x is a construct.
Use this method instead of instanceof to properly detect Construct
instances, even when the construct library is symlinked.
Explanation: in JavaScript, multiple copies of the constructs library on
disk are seen as independent, completely different libraries. As a
consequence, the class Construct in each copy of the constructs library
is seen as a different class, and an instance of one class will not test as
instanceof the other class. npm install will not create installations
like this, but users may manually symlink construct libraries together or
use a monorepo tool: in those cases, multiple copies of the constructs
library can be accidentally installed, and instanceof will behave
unpredictably. It is safest to avoid using instanceof, and using
this type-testing method instead.
Any object
true if x is an object created from a class which extends Construct.
Alarms for Lambda functions.
By itself, no alarms are created. Use the methods available to add alarms.

actionif you need an alarm to do multiple things.
