Hi all - anyone have any insight into my question below?
It would be so hugely helpful to have a doc on what metrics are available in storm, what data structures each contains and what each element means. I've amassed some idea of what thing mean, but I suspect I'm like others and still slightly confused on certain aspects.
If I ever get time, I'll volunteer to help doc this ... Thanks, L On 20/03/2014 17:42, Lajos wrote:
Hi all, I was trying to understand how the latency metrics are reported. I understand what each of them mean, but do they represent a random sampling of timings or some sort of averaging? If I send through 2000 messages and I see a process_latency of 1.411764705882353, is that averaged over the 2000 or just for the latest message? As a follow-up, is there a simple algorithm to create the same latency figures as are displayed in the UI but using the metrics figures themselves? I've tried various things and I can get some figures to line up, and others are way off. Thanks, Lajos
