This repository contains of two quick-and-dirty test clients for your project networks.
test-client.py-- Uses the network's API to connect to a single node and issue commands to fire up and shut down more nodes.network-grapher.py-- Uses the API to crawl the network and build a list of how the nodes are connected.
Each takes one argument, the node to connect to.
./test-client.py localhost:8000
./network-grapher.py localhost:8000
Like with the previous project, we will be using more thorough versions of these utilities to test your network in action. We strongly suggest that you add your own enhancements to these clients to perform more thorough tests. Think about different scenarios and interesting corner cases:
- What happens as the network gets much larger?
- What happens as churn increases (faster joins and leaves)?
- What happens when multiple startup and shutdown requests are executed in parallel?
-
Try running the
network-grapherwith the Unixwatchcommand to re-run and print the output every few seconds.watch ./network-grapher.py localhost:8000 -
With a little massaging, you might be able to get the
network-grapherto print valid descriptions for Graphviz, or another visualization library, to get an actual graphical map of your network.
RUN THE PROGRAM
Open terminal and go to uvrocks Locate directory and run ./node2.py --ip compute-X-X --port 8088
open another terminal and go to uvrocks locate directory and run ./test-client.py compute-X-X:8088
