Metrics and Key Performance Indicators

Cisco Cloud Observability displays the following metrics and key performance indicators (KPIs) for Amazon SQS. For more information, see Available CloudWatch metrics for Amazon SQS.

Display Name	Source Metric	Description
Approximate Age of Oldest Message (Seconds)	`ApproximateAgeOfOldestMessage`	The approximate age of the oldest non-deleted message in the queue.
Approximate Number of Message (Count)	`ApproximateNumberOfMessagesDelayed`	The number of messages in the queue that are delayed and not available for reading immediately. This can happen when the queue is configured as a delay queue or when a message has been sent with a delay parameter.
	`ApproximateNumberOfMessagesNotVisible`	The number of messages that are in flight. Messages are considered to be in flight if they have been sent to a client but have not yet been deleted or have not yet reached the end of their visibility window.
	`ApproximateNumberOfMessagesVisible`	The number of messages to be processed.
	`NumberOfEmptyReceives`	The number of `ReceiveMessage` API calls that did not return a message.
	`NumberOfMessagesDeleted`	The number of messages deleted from the queue.
	`NumberOfMessagesSent`	The number of messages added to a queue.
