Visualizer
NOTE: lots to fill in here!
- Make sure the Twisted Python library is installed on each node in the network
sudo apt-get install python-twisted
- Select one of the nodes in the network to run the stats server
- Start the statsserver listening on TCP port 8888 on all interfaces. The statsserver is a simple http server that is used to aggregate the information from all the nodes in the network
- This also starts the xstats daemon which retrieves XID count information from click and reports it to the statsserver
xianet -Z -other-options start
- Tell the remaining nodes to run the xstats daemon and send statistics to the statsserver on port 8888 on the specified IP address or host name.
xianet -z <address of machine running stats server> -other-options start
- Install Flash for your web browser (sorry!)
- Load the visualizer
firefox file:///home/yourname/xia-core/tools/visualizations/distributed_click/Visualizer.html
- Tell flash it's OK to use local storage with this app (may not be necessary)
- Right click on the setup screen
- Select Global Settings...
- Click the
Advancedtab - Click the
Trusted Location Settingsbutton - Add the
~/xia-core/tools/visualizations/distributed_click/folder to the list
The examples below show an echoserver running on host1 and an echoclient on router0
- Final Intent
- Next Hop
- The visualizer client is a Flash application that is unlikely to ever be updated again.
- Non-operative features:
- There is no ability to add addresses to the Saved Servers dropdown
- There is no way to save a Custom Layout for the Layout dropdown
- The display management traffic checkbox has no effect anymore because we have changed how routing messages are delivered
- The Show Map checkbox has no effect
- The delivery of statistics data to the stats server occasionally stutters, so the values displayed should be taken with a grain of salt.
