Once coverage monitoring has started, the code invokes and retrieves the original lambda's response.
Test Duration Requirement
Please note that tests must run for a minimum of 1s for SeaLights to calculate coverage. If your test duration is under 1s, adding a brief pause to your test will allow SeaLights to complete the coverage sampling process.
Step 6 - Terminating Coverage

Flag | Description | Type | Mandatory | Example |
|---|---|---|---|---|
| Set the location of all lambda functions root dir | List of paths | Yes, at least one path is required | “./function_1,./function_2" |
| Set the address of the collector URL | a valid URL | No, but if not set by ENV Var the footprints will not be set | https://collector.host:16500 |
| Set the path of saving the sealights_layer | a valid dir | No, but if not set a sealights_layer will be saved"./"a sealights_layer will be saved | "./" |
Alternatively to exporting the layer, you can use the public layers in aws:arn:aws:lambda:eu-west-1:442677231940:layer:sl-python-layer:7arn:aws:lambda:eu-west-2:442677231940:layer:sl-python-layer:7arn:aws:lambda:us-east-1:442677231940:layer:sl-python-layer:7arn:aws:lambda:us-west-2:442677231940:layer:sl-python-layer:7
sl_lambda_config.json
This json file contains the agent config parameter's that needed to be sent in each footprint.

The Content Uri in Sealights Layer should be to related
--exportlayerpathpath on sl-python configlambda commandThe '
AWS_LAMBDA_EXEC_WRAPPER: /opt/setupsealights-extension' is a mandatory env var to set in order to invoke Sealights Lambda handler
...
In addition to the mandatory 'AWS_LAMBDA_EXEC_WRAPPER: /opt/setupsealights-extension' environment variable there are more environment variables that override the sl_lambda_config.json values:

Where the collector URL should set to the real collector url.
after running this command a file called sl_lambda_config.json will be created.
