TraceMetrics Changelog

What's new in TraceMetrics 1.3.0

Dec 19, 2012
  • Hot update:
  • Now TraceMetrics is able to calculate delay, PDV and IPDV for UDP streams using IPv4. (IPv6 is not possible yet).
  • New mode of file reading , saving up to 50% of time analysis; to avoid bugs, the old method is still available (see the menu options on tracemetrics).
  • Update:
  • The setReceived and setDropped methods was corrected; trace files that do not contain logs of all devices will not cause errors anymore.
  • The structure of folders of code was updated.
  • Some revisions of java-doc
  • Bug fix:
  • Calculation of discard probability;
  • The interface for make graphics scripts to gnuplot works properly on streams with three or less calculated metrics.
  • UDP packet count.

New in TraceMetrics 1.2.0 (Aug 27, 2012)

  • [Update] UNow you can sort the columns display flow, results Throug / Good-put and Little.
  • [Update] Apparently, the variables "static ArrayList model" and "ArrayList files = new ArrayList ()" not being used. Were discussed.
  • [Update] All classes that use the getInstance () method had its builders set to private.
  • [Hot update] Now you can stop the analisis at any time.
  • [Feature] You can start the program with the - no-splash. Self explanatory :)
  • [Feature] Implemented a window for reporting bugs. Supports multiple instances and supports to provide extra information to the user (see builders).
  • [Hot feature] Auxiliary Interface to generate graphics for the GNU-plot, with support for line graphs and histograms.
  • [Feature] Support previewing data if you have gnuplot installed.
  • [Feature] Happen to some types of exceptions in the program, open the bug report automatically

New in TraceMetrics 1.0.1 (Apr 3, 2012)

  • [Feature] Basic Wimax support
  • [Feature] Analyzis time on Simulation tab
  • [Bugfix] A few counters were changed from 'int' to 'long' to prevent type overflow
