Show HN: Sping – An HTTP/TCP latency tool that's easy on the eye
I've frequently found myself using [nvitop](https://github.com/XuehaiPan/nvitop) to diagnose GPU/CPU contention issues.
The two best things about it are:
- It's easy to install if I can access pip in the container
- It makes a compelling screenshot (which helps me communicate with coworkers.)
With those two lessons in mind: Here is Sping!
Purpose: Help observe and diagnose latency issues at layer 4+ (TCP/HTTP/HTTPS)
Two good things about it:
- It's easy to install if you have pip. (Available at [service-ping-sping](https://pypi.org/project/service-ping-sping/) on PyPi)
- It makes a compelling screenshot.
Not sure if this is the kind of thing that anyone else would be interested in. But I've enjoyed making it and intend to keep using it.
