The Truth About "MEH-TRICS"

A long time ago, in a galaxy far, far away, I said a lot of inflammatory things about metrics. “Metrics are shit salad.” “Metrics are simply nerfed dimensions.” “Metrics suck,” “metrics are legacy,” “metrics and time series aggregates will fucking kneecap you.” I cannot tell a lie; Twitter will testify that I’ve spent the past six years ragging on metrics.

Ship software faster by removing bottlenecks and keep work flowing

We know customers and users today demand new features to be frequently released to their favorite apps. Plus they expect any bugs or issues hindering a great user experience to be fixed—and fast.

Moving in Concert: What is SD-WAN, and Where is it Going?

Software-defined WAN (SD-WAN) is a software overlay that decouples WAN configuration and management from the underlying network transport medium (5G/LTE, MPLS, xDSL, etc) and dynamically routes WAN traffic. To the uninitiated, that’s a mouthful. But it’s one of the most interesting trends of the last few years. Let’s jump on the bandwagon! Time for a primer on SD-WAN, why it matters, and where it’s heading now and into the future.

[Infographic] AWS SNS from a serverless perspective

The Simple Notification Service, or SNS for short, is one of the central services to build serverless architectures in the AWS cloud. SNS itself is a serverless messaging service that can distribute massive numbers of messages to different recipients. These include mobile end-user devices, like smartphones and tablets, but also other services inside the AWS ecosystem. SNS’ ability to target AWS services makes it the perfect companion for AWS Lambda.

End-to-End Application Performance Monitoring

In this blog, I’ll cover a real-world example of application performance troubleshooting a Java web app, hosted on JBoss Wildfly using Microsoft SQL as the backend database, including details of the analysis and diagnosis we had to perform in order to identify the root-cause of, and resolve, the performance issue.

Debugging Node.js Memory Leaks: How to Detect, Solve or Avoid Them in Applications

In this article, you’ll learn how to understand and debug the memory usage of a Node.js application and use monitoring tools to get a complete insight into what is happening with the heap memory and garbage collection. Here’s what you’ll get by the end of this tutorial. Memory leaks often go unnoticed. This is why I suggest using a tool to keep track of historical data of garbage collection cycles and to notify you if the heap memory usage starts spiking uncontrollably.

IoT Security: How Important are Logs for System?

IoT has rapidly moved from a fringe technology to a mainstream collection of techniques, protocols, and applications that better enable you to support and monitor a highly distributed, complex system. One of the most critical challenges to overcome is processing an ever-growing stream of analytics data, from IoT security data to business insights, coming from each device. Many protocols have been implemented for this, but could logs provide a powerful option for IoT data and IoT monitoring?
