Lambda metrics

This topic covers the AWS Lambda metrics that can be gathered when monitoring your AWS cloud account. For information about using AWS Lambda to collect logs from your AWS cloud account, see Add logs from AWS. For information about AWS Lambda instrumentation for service entities, see AWS Lambda instrumentation.

AWS Lambda lets you run code without provisioning or managing servers. Ensure your cloud platform is configured in SolarWinds Observability to collect this service's data. See Add an AWS cloud account. CloudWatch metrics must also be enabled for this service in the AWS Console for the metric data to be available.

Many of the collected metrics from AWS Lambda entities are displayed as widgets in SolarWinds Observability explorers; additional metrics may be collected and available in the Metrics Explorer. You can also create an alert for when an entity's metric value moves out of a specific range. See Entities in SolarWinds Observability for information about entity types in SolarWinds Observability.

The following table lists some of the metrics collected for these entities. To see the AWS Lambda metrics in the Metrics Explorer, type AWS.Lambda in the search box.

Metric Units Description
sw.metrics.healthscore Percent (%)

Health score. A health score provides real-time insight into the overall health and performance of your monitored entities. The health score is calculated based on anomalies detected for the entity, alerts triggered for the entity's metrics, and the status of the entity. The health score is displayed as a single numerical value that ranges from a Good (70-100) to Moderate (40-69) to Bad (0-39) distinction.

To view the health score for AWS Lambda entities in the Metrics Explorer, filter the sw.metrics.healthscore metric by entity_types and select awslambda.

AWS.Lambda.ConcurrentExecutions Count

ConcurrentExecutions. The maximum number of function instances that are processing events.

AWS.Lambda.DeadLetterErrors Count

DeadLetterErrors. The total number of times that Lambda attempts to send an event to a dead-letter queue but fails. Dead-letter errors can occur due to permissions errors, misconfigured resources, or size limits.

AWS.Lambda.Duration milliseconds (ms)

Duration. The average amount of time that your function code spends processing an event.

AWS.Lambda.Errors Count

Errors. The total number of invocations that result in a function error.

AWS.Lambda.Invocations Count

Invocations. The total number of times that a function code is invoked, including successful invocations and invocations that result in a function error.

AWS.Lambda.IteratorAge milliseconds (ms)

IteratorAge. The maximum amount of time between when a stream receives the record and when the event source mapping sends the event to the function.

AWS.Lambda.Throttles Count

Throttles. The total number of invocation requests that are throttled. When all function instances are processing requests and no concurrency is available to scale up, Lambda rejects additional requests with a TooManyRequestsException error.
