Lambda
Overview
AWS Lambda lets you run code without provisioning or managing servers.
Setup
Installation
If you haven't already, first set up the AWS CloudWatch integration. No additional steps are needed for installation.
Configuration
On the AWS CloudWatch integration page, ensure that the Lambda service is selected for metric collection.
Metrics
| Name | Description |
|---|---|
|
Invocations (count) |
Measures the number of times a function is invoked in response to an event or invocation API call. This includes successful and failed invocations, but does not include throttled attempts. |
|
Errors (count) |
Measures the number of invocations that failed due to errors in the function (response code 4XX). |
|
Dead Letter Error (count) |
Incremented when Lambda is unable to write the failed event payload to your configured Dead Letter Queues. |
|
Duration (milliseconds) |
Measures the elapsed wall clock time from when the function code starts executing as a result of an invocation to when it stops executing. The maximum data point value possible is the function timeout configuration. |
|
Throttles (count) |
Measures the number of Lambda function invocation attempts that were throttled due to invocation rates exceeding the customer's concurrent limits (error code 429) |
|
IteratorAge (milliseconds) |
Emitted for stream-based invocations only (functions triggered by an Amazon DynamoDB stream or Kinesis stream). Measures the age of the last record for each batch of records processed. |
