// PutMetricAlarm API operation for Amazon CloudWatch.
//
// Creates or updates an alarm and associates it with the specified Amazon CloudWatch
// metric. Optionally, this operation can associate one or more Amazon SNS resources
// with the alarm.
//
// When this operation creates an alarm, the alarm state is immediately set
// to INSUFFICIENT_DATA. The alarm is evaluated and its StateValue is set appropriately.
// Any actions associated with the StateValue are then executed.
//
// When updating an existing alarm, its StateValue is left unchanged, but it
// completely overwrites the alarm's previous configuration.
//
// If you are using an AWS Identity and Access Management (IAM) account to create
// or modify an alarm, you must have the following Amazon EC2 permissions:
//
// ec2:DescribeInstanceStatus and ec2:DescribeInstances for all alarms on Amazon
// EC2 instance status metrics.
//
// ec2:StopInstances for alarms with stop actions.
//
// ec2:TerminateInstances for alarms with terminate actions.
//
// ec2:DescribeInstanceRecoveryAttribute, and ec2:RecoverInstances for alarms
// with recover actions.
//
// If you have read/write permissions for Amazon CloudWatch but not for Amazon
// EC2, you can still create an alarm but the stop or terminate actions won't
// be performed on the Amazon EC2 instance. However, if you are later granted
// permission to use the associated Amazon EC2 APIs, the alarm actions you created
// earlier will be performed. For more information about IAM permissions, see
// Permissions and Policies (http://docs.aws.amazon.com/IAM/latest/UserGuide/PermissionsAndPolicies.html)
// in Using IAM.
//
// If you are using an IAM role (e.g., an Amazon EC2 instance profile), you
// cannot stop or terminate the instance using alarm actions. However, you can
// still see the alarm state and perform any other actions such as Amazon SNS
// notifications or Auto Scaling policies.
//
// If you are using temporary security credentials granted using the AWS Security
// Token Service (AWS STS), you cannot stop or terminate an Amazon EC2 instance
// using alarm actions.
