It has a modular design, allowing individual analysis plug-ins to be registered and used at any time.\n\nKarbon is perfect for identifying performance issues related to **System Calls ONLY**. It is completely blind regarding the application code. It *can not* resolve symbols, *nor* detect software-induced performance penalties.\n\nThis means that after identifying the 'hot' system calls you will still need to go through your code and identify were the problem is located.\n\n## Creating a trace file\n\nKarbon works with most of trace file formats, however it's most optimal to create them with the following command line:\n\n```\nstrace -TtttfFvx -s 256 -o trace.dmp -- /path/to/application args ...\n```\n\nIf you prefer, you can live-trace the application through the Karbon GUI.\n\n## Running Karbon\n\nYou will need __Java Runtime__ installed to your system. In most of the cases you will only need to double-click the `.jar`, but if you have trouble, try running it from the command-line:\n\n```\njava -jar Karbon.jar\n```\n\n### Current Plugins\n\nThe following list enumerates all the currently available plug-ins and their use:\n\n- **Classifier** : Traces all system calls that perform operations on file descriptors, such as Filesystem (`fopen`,`fclose` etc.), Memory (`mmap`, `mprotect` etc.), Network (`socket`,`sockopt` ...) or Misc (`pipe`, `socketpair` etc.).\n- **System Calls** : An overview plug-in that summarises the statistics from all system calls, such as error rate, time spent on errors and overall time spent. \n- **Socket Tracker** : A specialised plug-in that tracks socket creation and actions. This plugin also resolves the endpoint details (IP address or UNIX socket) and the traffic through them.\n- **File Tracker** : A specialised plug-in that tracks individual files accessed by the application, including detailed I/O statistics.\n- **Hotspot Tracker** : A specialised plug-in that identifies  operations that take too much time to complete, including System Calls, Filesystem Operations and Processes.\n- **Process Tracker** : A specialised plug-in that tracks process creation and behaviour. It constructs a comprehensive process tree and evolution graph in order to identify fork-related problems.\n- **Time Utilisation** : A specialised plug-in that summarises the time spent in various operations, such as File I/O or Network I/O.\n\n## License\n\nKarbon - Tracefile Analyzer GUI \nCopyright (C) 2010-2015 Ioannis Charalampidis\n\nThis program is free software: you can redistribute it and/or modify\nit under the terms of the GNU General Public License as published by\nthe Free Software Foundation, either version 3 of the License, or\n(at your option) any later version.\n\nThis program is distributed in the hope that it will be useful,\nbut WITHOUT ANY WARRANTY; without even the implied warranty of\nMERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
