In part 1 of this series, I cover important concepts about measuring the accuracy of time on Amazon EC2 instances . I discussed calculating ClockErrorBound (?) and using its value as a range between which system time is accurate. In this part, I walk through the process of using Amazon CloudWatch to measure and monitor […]

This two-part series discusses the measurement and management of time accuracy on Amazon EC2 instances. Part 1 covers the important concepts related to system and reference time. Part 2 covers the mechanism of measure, monitor, and maintain accurate system time on EC2 instances. A large and diverse set of customer workloads depends on the observed […]

Monitoring the health of your API endpoints is important to understand the overall health of your workloads. You can use Amazon CloudWatch Synthetics to monitor your API endpoints and understand the overall health of your workloads. CloudWatch Synthetics canaries allow you to monitor API endpoints by creating HTTP steps and configuring the request type, endpoint URL, […]

In this blog post, we will show you how you can programmatically deploy the Amazon CloudWatch agent using the AWS Cloud Development Kit (AWS CDK) as you create your Amazon Elastic Compute Cloud (Amazon EC2) instances. You can use the command line, AWS Systems Manager, and AWS CloudFormation to install the CloudWatch agent on your EC2 instances. We also recently announced that the […]

If you’ve ever run a containerized workload, you know that it can be tricky to check what’s happening in your container. In this blog post, I show how you can monitor and scale your Amazon Elastic Container Service (Amazon ECS) on AWS Fargate application using Prometheus metrics. Although there is more information about Prometheus already […]

In this guest post, Ciaran Kearney, Data Engineer at multinational telecommunications company BT discusses how BT built a monitoring solution using Amazon CloudWatch dashboards, composite alarms, and embedded metric format to support the monitoring of millions of devices. Customers with high-cardinality monitoring use cases often face challenges when it comes to implementing observability. Monitoring high-cardinality workloads […]

You can use rules in Amazon CloudWatch Contributor Insights to gain security visibility into your VPC flow logs. The rules analyze flow logs in targeted groups in Amazon CloudWatch Logs and display the Top-N contributors for a given log field or combination of log fields. In this post, I’ll show you how to set up CloudWatch Contributor Insight rules for VPC flow logs. I’ll demonstrate how to:

Map the VPC flow log format to rules in Contributor Insights.
Explain how a single rule can be used to monitor many VPC flow logs.
Walk through some sample rules and show them in a CloudWatch dashboard.

Amazon CloudWatch Dashboards are a great way to monitor your AWS resources. During peak events when you are expecting high traffic, monitoring your AWS resources helps you stay ahead of any issues that may arise. You might want a customized and automated dashboard that can be used during a seasonal event, important releases, holidays, and […]

Each AWS service requires explicit access to resources, endpoints, and objects that reside in the domain of another service. This is referred to as the permission boundary. Services like AWS Config, Amazon Macie, and AWS GuardDuty require an AWS Identity and Access Management (IAM) role that grants access to resources outside of its control. Understanding […]

Many organizations get access to their AWS resources using a Direct Connect connection or a Site-to-Site VPN. AWS Site-to-Site VPN creates a secure connection between your data center or branch office and your AWS cloud resources.  In this post, we will see how to monitor your Cisco CSR VPN tunnel and BGP (Border Gateway Protocol) […]
