   * A *tcpdump trace* for every upload/download tests. This is a standard  
trace file for all packets (except the initial syn & syn/ack exchange). The  
tcpdump and tcptrace programs can read these files.

   * A *web100 snaplog trace* for every upload/download test. This file  
contains all the the web100 kernel MIB variables in 5 msec increments. The  
NDT package comes with a utility (called genplot) that can convert these  
trace files into text or xplot graph files. Alternatively the user can  
write their own analysis program using the web100 library functions.
-The server logs the final value of 50 web100 variables. It also reports  
some analysis details. This data is written out in a comma (,) separated  
line, so parsing the data is a matter of 'knowing' what variable is in what  
position in the line. The details for this are in the code.
-
-To make it easier to use this data, the NDT server writes out a meta data  
file (.meta). This metadata file contains the names of the above files, the  
clients & servers IP addr and FQDN, and the encoded line of web100/analysis  
data. A sample of that data is

the *web100srv.log* file. The list of logged variables with a short  
description can be found in the [NDTProtocol#Appendix_A._web100_variables  
NDT Protocol document].

`times` routine results recorded using a 100ms interval.
