To deliver outstanding customer experience for your applications and websites, you need reliable benchmarks that measure what good customer experience looks like. Dynatrace Visually complete is a point-in-time web performance metric that measures when the visual area of a page has finished loading. In terms of user experience measurements, optimizing Visually complete timing is more […]
Dynatrace is pleased to announce the Early Adopter release of OneAgent full-stack monitoring for Linux on the ARM 64-bit AArch64 architecture with OneAgent version 1.191.
We're happy to announce that with the releases of OneAgent version 1.191 and version 1.193, we'll be further improving the security of OneAgent installation and monitoring.
In the past, Dynatrace offered a three-month upgrade grace period for upstream Kubernetes distributions, Red Hat OpenShift, and VMware Tanzu Application Service due to the offset between delivery schedules. As of May 2020, Dynatrace provides nearly same-day support for all container platforms. Thus our support model no longer requires the three-month grace period. For all OneAgent releases prior to May 2020 (earlier than OneAgent version 1.191), Dynatrace will extend support by three months to honor pre-existing OneAgent installations based on the previous support model.
