Network Tool
Ping Test Dashboard
A lightweight browser dashboard that samples remote endpoints, charts request timing, and summarizes min, median, average, max, and jitter.

What This Project Shows
This project shows practical observability thinking in a very small tool: repeated measurements, visual trend, and summary statistics instead of a single anecdotal request time.
Problem
What Needed To Be Solved
One request timing does not explain network stability. A useful debugging dashboard needs repeated samples and a way to compare spikes, spread, and central tendency.
Approach
How I Built The Solution
I used browser fetch timing with cache-busting query strings and no-store requests, then fed each run into a Chart.js time series and a compact statistics function.
Outcome
What It Demonstrates
The project communicates the ability to build small operational tools that turn noisy runtime behavior into readable feedback.
Evidence From Source
Source signal
The single file includes `pingUrl`, `computeStats`, `runRegion`, dynamic chart creation, and per-region consoles.
Engineering decision
Even though browser fetch is not ICMP ping, the tool is explicit about measuring client-visible request responsiveness.
