Log AWS VPC Flows

Log AWS VPC Flows

As I transition to working in “the cloud” more I am embracing the new technologies and methodologies. However, I’m also trying to replicate what I do in on-prem environments when it makes sense. One way I like to collect and analyze data is using NetFlow. NetFlow provides network conversation details at a higher and summarized level. This has led to quicker recovery time on numerous occasions, or avoided issues entirely. It isn’t exactly the same, but I have figured out how to log AWS VPC flows to provide the data. Here’s a brief walk through of the setup.   Create Flow Logs The first step is to select the VPC and then the “Create Flow Log” menu item from the “Actions” drop down.   See them attached to VPC After confirming its creation I saw the log ID listed in the “Flow Logs” tab.   View Configured Flow Logs Hopping over to the CloudWatch logs I could see my newly created log group.   Log View After selecting the log, I could...

AWS Monitoring with IFTTT

AWS Monitoring with IFTTT

Performance monitoring is two-fold. There is proactive performance monitoring and reactive investigation. The majority of my posts and case studies reflect the latter. This post is more related to the former. Services on premise typically rely on SLAs, NetFlow, scripts, synthetic transactions and more to provide monitoring and alerting. While some of this is possible in the cloud to keep track of specific pieces, you first need a good foundation by knowing if the underlying technology by your cloud provider is operating as expected. In this example, I will walk through setting up an alert to monitor individual Amazon Web Services and send a notification using an IFTTT applet. Create the Applet Before creating an applet/recipe, you might want to see if one is already available with the functionality you need in IFTTT's discover section. If one isn't available, you can create one following their instructions here. I will skip the step by step that they provided, and demonstrate how you might...
