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.

(i.e. # HTTP monitoring with interactive UI sping google.com )
Would you mind telling me what environment you found this behavior in, and how you installed the app?
I've been testing in ubuntu containers doing:
Thank you so much!!*EDIT:*

This is now fixed in 0.2.11. Thanks @johnQdeveloper
