[Planetlab-users] How to manage a large number of nodes effciently?

[Jin Liang]

Hi,
   If you want the "live" status of the nodes, you cannot
do it continuously. Therefore the best way might be to
run a script and query the status when you want to. To
improve the performance, you can either use parallel query
(e.g., using pssh or vxargs), or build a dynamic structure
to "relay" the query and aggregate the results. The latter
is the approach taken by our MON (http://cairo.cs.uiuc.edu/~mon/)
system. Although note MON only provides summary (e.g., average,
top k) status data, not the complete data that CoMon provides.
