+ **Attempt** – Represents a single invocation attempt, including any overhead introduced by the Lambda service\. Examples of overhead are time spent initializing the function's code and function execution time\.
+ **Lambda function segment** – Represents execution time for the function for a given invocation attempt\. It starts when the function handler starts executing and ends when the function terminates\. This segment can include three types of subsegments:
+ **Initialization** – The time spent running the `initialization` code of the function, defined as the code outside the Lambda function handler or static initializers\.
+ **Downstream calls** – Calls made to other AWS services from the Lambda function's code\.
+ **Custom subsegments** – Custom subsegments or user annotations that you can add to the Lambda function segment by using the X\-Ray SDK\.

The Lambda function segment is generated by the Lambda service on behalf of the customer. It overwrites any segment created in the Lambda function code, including segments generated by the X-Ray SDK to capture requests via middleware. If a segment is created in Lambda function code, it is implemented as a facade segment. The facade segment only allows custom subsegments to be added to and deleted from it; all other segment operations are treated as no-ops.

**Note**
For each traced invocation, Lambda emits the Lambda service segment and all of its subsegments\. These segments are emitted regardless of the runtime and require you to use the X\-Ray SDK for AWS API calls\.
