[Nfd-dev] monitoring data plance

[Beichuan Zhang]

Hi John,

The current testbed status page monitors the control plane, i.e., prefixes in the routing table. I think we also need monitor data plane reachability e.g., measured by ndnping. 

More specifically,

- Each node runs a script that reads the list of prefixes from a local file, and ndnping each prefix for a number of times, say 10. The output is published as an HTML or XML page under the current web server on the node. The measurement is done periodically. 

- The stat collection script at WashU retrieves the page from individual node, parse them, and the result is another table to the current status page. This table has the same layout as the current table, but in each cell it shows the % of ping packets received in the most recent measurement.

This information would be helpful once apps are deployed on the testbed. What do you think?
