AWS lambda metricset

AWS Lambda monitors functions and sends metrics to Amazon CloudWatch. These metrics include total invocations, errors, duration, throttles, dead-letter queue errors, and iterator age for stream-based invocations.

AWS Permissions

edit

Some specific AWS permissions are required for IAM user to collect AWS EBS metrics.

cloudwatch:ListMetrics
tag:getResources
sts:GetCallerIdentity

Dashboard

edit

The aws lambda metricset comes with a predefined dashboard. For example:

Configuration example

edit

- module: aws
  period: 300s

    - lambda
  # This module uses the aws cloudwatch metricset, all
  # the options for this metricset are also available here.

Metrics

edit

Please see more details for each metric in lambda-cloudwatch-metric.

Metric Name	Statistic Method
Invocations	Average
Errors	Average
DeadLetterErrors	Average
DestinationDeliveryFailures	Average
Duration	Average
Throttles	Average
IteratorAge	Average
ConcurrentExecutions	Average
UnreservedConcurrentExecutions	Average
ProvisionedConcurrentExecutions	Maximum
ProvisionedConcurrencyInvocations	Sum
ProvisionedConcurrencySpilloverInvocations	Sum
ProvisionedConcurrencyUtilization	Maximum

This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.
