This file describes logging changes made to the DTN2 code for the N4C summer 2010. When analysing the logs from our 2009 trial we hit on a number of cases where the 'info' logs didn't have enough information for us; the main one being that those logs don't allow you to trace a bundle across multiple nodes since the bundle creation time isn't logged except in debug mode which is far too verbose. We also had to do a good bit of work to munge log file content into a form from which we could generate plots and do statistics. So the changes here are to fix those issues. The files touched all have the "S10" string in them and include: servlib/bundling/S10Logger.cc servlib/bundling/S10Logger.h daemon/dtnd.cc servlib/bundling/DTNServer.cc servlib/bundling/BundleDaemon.cc servlib/contacts/ContactManager.cc CSV columns: col#,name,FROMAPP,FROMDB,DELIVERED,TAKECUST,RELCUST,EXPIRY,TX,RX,TXADMIN,RXADMIN,DUP,CONTUP,CONTDOWN,STARTING,EXITING 1,rfc3339date,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x 2,time_t.usec,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x 3,Logging-node,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x 4,Event,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x 5,Size,x,x,x,x,x,x,x,x,x,x,x,,,, 6,Src-EID,x,x,x,x,x,x,x,x,x,x,x,,,, 7,Bundle-ID,x,x,x,x,x,x,x,x,x,x,x,,,, 8,Dest-EID,x,x,x,x,x,x,x,x,x,x,x,,,, 9,Expiry,x,x,x,x,x,x,x,x,x,x,x,,,, 16,Blfags,x,x,x,x,x,x,x,x,x,x,x,,,, 10,Peer,,,,,,,x,x,x,x,x,x,x,, 11,Other-bund-Src,,,,,,,,,x,x,,,,, 12,Other-bundle-ID,,,,,,,,,x,x,,,,, 13,Other-time,,,,,?,?,,,,,?,,x,, 14,Cont-type,,,,,,,,,,,,x,x,, 15,Duration,,,,,?,?,,,,,?,,x,,
