profilelambda

Decorators and utils for profiling / debugging functions - especially AWS lambda

Just adding one line for debug called arguments and profiling your function. Your AWS lambda can be triggered by different source of events, thus, different arguments.

• Free software: MIT license

Features

• Single code line for profiling decorated function
• Also print out called arguments for debugging

Example

Your broken function

def lambda_handler(event, context):
    do_something()

Adding profiler and argument debugging

from profilelambda import profile

@profile
def lambda_handler(event, context):
    print("Hello this is my lambda")

Output:

Function 'lambda_handler' got arguments ({}, None) and keyword arguments {}
Hello this is my lambda
