# This token is used to associate AWS CloudWatch logs to a log in your Logentries account.

Listing 1 below shows an example of the configuration file, le_config.py. You set the token of the log set to which you want SNS messages to be logged.

le_config.py is part of the code you’ll find on GitHub. Once you have the code in hand, you need to add settings to the configuration file, le_config.py. The code you will be installing in a Lambda function is available here.

Getting and Configuring the SNS Code from GitHub Second, using the Logentries’s code allows you to gain experience using Lambda functions in a very clever manner. First, should you so desire, you can explore the code provided by Logentries to learn the details of programming Lambda functions in Python. Using the Logentries code kills two birds with one stone. Still, demonstrating now to get a Lambda function to interact with SNS explains the concepts you need to know well. However, demonstrating a more complex use of Lambda functions would require time and space well outside the scope of a blog entry. Lambda functions are very powerful and you can do a lot with them well outside the scope of forwarding messages to a cloud based site such as Logentries. The reason that I chose SNS technology to demonstrate the power of Lambda functions is one of simplicity. Figure 2 below shows the steps in the process. The result will be that any message to the SNS Topic you created will be forwarded onto the Logentries log set associated with the token that you set in configuration file.

In this article, I am going to show you how to install the Logentries SNS Lambda code in your own Lambda function and then create a SNS Topic to which the Lambda function will subscribe. You can download this code from GitHub ( ). The details about how this code works in conjunction with Amazon Web Services is shown below in Figure 1:įigure 1: The Lambda function will Logentries code will subscribe to an SNS Topic This code is executed from within a Lambda function.

The company has created code that forwards messages sent to a topic in Amazon’s Simple Notification Service (SNS) onto a log set in Logentries. Logentries has put the power of Lambda functions to good use. For example, you can create a Lambda function that takes a list of stock symbols and does some analysis on the list using other cloud based services in order to suggest the best stock to buy. A Lambda function is a feature in Amazon Web Services that allows you to put a discrete piece of computing logic up in The Cloud and then access that logic to meet a particular need. Amazon Web Services Lambda functions are very cool.
