Dynatrace
NOVEMBER 6, 2023
With topics ranging from best practices to cloud cost management and success stories, the conference will be a valuable resource for understanding observability and getting started. Dynatrace enables teams to specify SLOs, such as latency, uptime, availability, and more. and bring that to you while your program continues to run.”

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Or even on a plane.

For example, iostat(1), or a monitoring agent, may tell you your average disk latency, but not the distribution of this latency. For smaller environments, it can be of more use helping eliminate latency outliers. The probe is BEGIN , a special probe that runs at the beginning of the program (like awk). was just released.
