 == Introduction ==

-The NDT may store test results data in the following files:
-
-|| *File* || *Scope* || *Mandatory/Optional* ||
-|| *tcpdump trace* || C2S/S2C tests || *optional* ||
-|| *web100 snaplog trace* || C2S/S2C tests || *optional* ||
-|| *web100srv.log* || test session || mandatory ||
-|| *cputime trace* || test session || *optional* ||
-|| *meta data file* || test session || mandatory ||
+The NDT uses the following files to store test results data:
+
+|| *File* || *Scope of the collected data* || *Always used?* ||
+|| *tcpdump trace* || C2S/S2C tests || *NO* (enabled by `-t, --tcpdump`  
options) ||
+|| *web100 snaplog trace* || C2S/S2C tests || *NO* (enabled by `--snaplog`  
option) ||

syn/ack exchange). The tcpdump and tcptrace programs can read these files.

 ==Displaying collected data==

+The tcpdump files can be read using [http://www.tcpdump.org/ tcpdump] and  
[http://www.tcptrace.org/ tcptrace] programs.

 The NDT server also contains a Java application that can look through the  
NDT log files and link log entries to trace files, and it also simplifies  
the viewing of this data. The utility will need to be rewritten slightly to  
take advantage of the meta files instead of (in addition to) the log files.

 The detailed tcpdump and snaplog files can be used to re-examine the test  
to see what happened, i.e.:
