In today's fast-paced digital landscape, organizations are increasingly embracing multi-cloud environments and cloud-native architectures to drive innovation and deliver seamless customer experiences. However, the 2024 State of Observability report from Dynatrace reveals that the explosion of data generated by these complex ecosystems is pushing traditional monitoring and analytics approaches to their limits.

As organizations strive for observability and data democratization, OpenTelemetry emerges as a key technology to create and transfer observability data. OpenTelemetry is gaining popularity because it’s considered a standard, and that’s why it’s a common choice for creating future-proof solutions for years to come. To answer the growing demand for OpenTelemetry, Dynatrace is proud to announce the release of the Dynatrace OpenTelemetry Collector distribution (Dynatrace OTel Collector).

I've been spending a lot of time looking at the performance of European sites lately, and have found that the consent management platforms (CMPs) are consistently creating a bit of a false reality for folks when trying to understand performance using synthetic monitoring. Admittedly, this is not a new topic, but I feel that it's important enough that it warrants another PSA.

TL;DR LLMs and other GenAI models can reproduce significant chunks of training data. Specific prompts seem to “unlock” training data.

I often encounter the phrases problem space and solution space. People use these words to try and articulate the types of work and activities they are referring to, or where they are in the process of building something new. Unfortunately, rather than aiding communication, I notice that these words are so highly ambiguous that more time is spent debating what they mean than is gained by using them to improve communication and collaboration.
