Fields

• faasName :: Text

  The name of the single function that this runtime instance executes.

  This is the name of the function as configureddeployed on the FaaS platform and is usually different from the name of the callback function (which may be stored in the code.namespacecode.function span attributes).

  Examples: 'my-function'

• faasId :: Maybe Text

  The unique ID of the single function that this runtime instance executes.

  Depending on the cloud provider, use:

  • AWS Lambda: The function ARN. Take care not to use the "invoked ARN" directly but replace any alias suffix with the resolved function version, as the same runtime instance may be invokable with multiple different aliases.
  • GCP: The URI of the resource
  • Azure: The Fully Qualified Resource ID.

  Examples: 'arn:aws:lambda:us-west-2:123456789012:function:my-function'

• faasVersion :: Maybe Text

  The immutable version of the function being executed.

  Depending on the cloud provider and platform, use:

  • AWS Lambda: The function version (an integer represented as a decimal string).
  • Google Cloud Run: The revision (i.e., the function name plus the revision suffix).
  • Google Cloud Functions: The value of the K_REVISION environment variable.
  • Azure Functions: Not applicable. Do not set this attribute.

  Examples: '26', 'pinkfroid-00002'

• faasInstance :: Maybe Text

  The execution environment ID as a string, that will be potentially reused for other invocations to the same function/function version.

  AWS Lambda: Use the (full) log stream name.

  Examples: '20210628/[$LATEST]2f399eb14537447da05ab2a2e39309de'

• faasMaxMemory :: Maybe Int

  The amount of memory available to the serverless function in MiB.

  It's recommended to set this attribute since e.g. too little memory can easily an AWS Lambda function from working correctly. On AWS Lambda, the environment variable AWS_LAMBDA_FUNCTION_MEMORY_SIZE provides this information.

  Examples: '128'
