Dynatrace leverages new AWS Lambda extensions for seamless end-to-end observability

Dynatrace

Dynatrace news. AWS Lambda is the fastest growing technology for serverless workloads and helps developers innovate faster. It removes the burden of managing underlying infrastructure and is broadly adopted for cloud-native application environments. But serverless functions don’t exist in a vacuum. It’s critical that you understand how they impact your customer-facing web applications, mobile apps, or APIs and how they interact with other functions, services, and classic technology stacks.

10 Rules To Integrate Third-Party Scripts

DZone

Introduction. Third-party scripts can cause negative load-time effects. Why is this an issue? Well, in Google’s view, a poorly-optimized page should not rank highly. Instead, search results should favor pages with fundamental design strengths—including JavaScript minification, rapid execution time, and render-friendly scripting. In reflection of this belief, Google has planned the gradual release of a major update to its search algorithm that is scheduled for June through August of 2021.

Dynatrace adds OpenTelemetry trace ingest for open, automatic, and intelligent observability

Dynatrace

Dynatrace news. Today’s highly complex microservices environments require IT operations and SRE teams to observe each service and transaction end-to-end. Any observability blind spot imposes a risk, potentially increasing the time it takes to identify the root cause of a problem and address it. With the extremely successful OpenTelemetry project (to which Dynatrace actively contributes) having recently reached a key milestone with the OpenTelemetry Tracing Specification version 1.0, cloud servic

Poor Disk Performance

Brendan Gregg

People often tell me they don't understand performance tool output because they can't tell what's "good" or "bad." It can be hard as performance is subjective. What's good for one user may be bad for another. There are also cases where I can't tell either: The tools only provide clues for further analysis. I recently encountered terrible disk performance and thought it'd be useful to collect Linux tool screenshots and share them for reference.

What are the best multi-browser testing tools?

When we write scripts for one browser, they may not necessarily run on all browsers. It’s a no-brainer. And, we all know that a few browsers can limit certain features. For instance, if we design features that run on Safari on Mac OS, those features may not function across other browsers. To ensure the features run uniformly across various browsers and OS versions that our users have, we should perform multi-browser testing.
