[SOLVED] How to integrate X-Ray with AWS Lambda function on Command line

How to integrate X-Ray with AWS Lambda function on Command line

From the console, it is possible to activate lambda integration with x-ray through the following steps: From your function in the console > Configuration tab > Advanced dropdown/section > check Enable Active Tracing checkbox > Save.

I couldn't find documentation on how to get the above result in command line so I can easily apply that to all my lambdas instead of going to the individual ones in the console.

Solution

You can use the following flag via create-function or update-function-configuration.

--tracing-config '{ "Mode": "Active" }'

From the man page:

--tracing-config (structure)

Shorthand Syntax:

   Mode=string

JSON Syntax:

   {
     "Mode": "Active"|"PassThrough"
   }

All flags for a given command can be found using

aws <service> <command> help

I've opened an item with the Lambda team to include it on the X-Ray integration page found here:
