AWS Lambda is a compute service that allows code to run without provisioning or managing servers. AWS Lambda executes code only when needed and scales automatically, from a few requests per day to thousands per second.
The cost is based on the compute time that is consumed. For example, you pay only for the compute time you consume; there is no charge when your code is not running.
With AWS Lambda:
Code is run for virtually any type of application or back-end service - all with zero administration.
Code is run on a high-availability compute infrastructure and
Compute infrastructure performs all of the administration of the compute resources, including:
- server and operating system maintenance.
- capacity provisioning and automatic scaling.
- code monitoring and logging.
Use the AWS public cloud integration to discover and collect metrics against the AWS service.

Supported metrics
| OpsRamp Metric | Metric Display Name | Unit | Aggregation Type |
|---|---|---|---|
| aws_lambda_Invocations Measures the number of times a function is invoked in response to an event or invocation API call. | Invocations | Count | Sum |
| aws_lambda_Errors Measures the number of invocations that failed due to errors in the function (response code 4XX). | Errors | Count | Sum |
| aws_lambda_Duration Measures the elapsed wall clock time from when the function code starts executing as a result of an invocation to when it stops executing. | Duration | Milliseconds | Average |
| aws_lambda_Throttles Measures the number of Lambda function invocation attempts that were throttled due to invocation rates exceeding the customers concurrent limits (error code 429). | Throttles | Count | Sum |
| aws_lambda_DeadLetterErrors Incremented when Lambda is unable to write the failed event payload to your functions dead-letter queue. | DeadLetterErrors | Count | Sum |
| aws_lambda_IteratorAge Measures the age of the last record for each batch of records processed. Age is the difference between the time Lambda received the batch, and the time the last record in the batch was written to the stream. | IteratorAge | Milliseconds | Average |
| aws_lambda_ProvisionedConcurrentExecutions Number of events that are being processed on provisioned concurrency. For each invocation of an alias or version with provisioned concurrency, Lambda emits the current count. | ProvisionedConcurrentExecutions | Count | Average |
| aws_lambda_ProvisionedConcurrencyInvocations Number of invocations that are run on provisioned concurrency. Lambda increments the count once for each invocation that runs on provisioned concurrency. | ProvisionedConcurrencyInvocations | Count | Sum |
| aws_lambda_ProvisionedConcurrencySpilloverInvocations Number of invocations that are run on standard concurrency, when all provisioned concurrency is in use. For a version or alias that is configured to use provisioned concurrency, Lambda increments the count once for each invocation that runs on non-provisioned concurrency. | ProvisionedConcurrencySpilloverInvocations | Count | Sum |
| aws_lambda_ProvisionedConcurrencyUtilization Number of events that are being processed on provisioned concurrency, divided by Total amount of provisioned concurrency allocated. | ProvisionedConcurrencyUtilization | Count | Average |
| aws_lambda_ConcurrentExecutions Measures the sum of concurrent executions for a given function at a given point in time. | ConcurrentExecutions | Count | Average |
