fstrace - Introduction to the fstrace command suite


   The commands in the fstrace command suite are the interface that system
   administrators employ to trace Cache Manager operations for debugging
   purposes. Examples of Cache Manager operations are fetching file data
   or the status information used to produce output for the UNIX ls

   The fstrace command interpreter defines an extensive set of Cache
   Manager operations as the "cm" event set.  When the event set is
   activated, the Cache Manager writes a message to the "cmfx" trace log
   in kernel memory each time it performs one of the defined operations.
   The log expands only to a defined size (by default, 60 KB), after which
   it is overwritten in a circular fashion (new trace messages overwrite
   the oldest ones). If an operation of particular interest occurs, the
   administrator can afterward display the log on the standard output
   stream or write it to a file for later study. For more specific
   procedural instructions, see the OpenAFS Administration Guide.

   There are several categories of commands in the fstrace command suite:

   *   Commands to administer or display information about the trace log:
       fstrace clear, fstrace lslog, and fstrace setlog.

   *   Commands to set or display the status of the event set: fstrace
       lsset and fstrace setset.

   *   A command to display the contents of the trace log: fstrace dump.

   *   Commands to obtain help: fstrace apropos and fstrace help.


   All fstrace commands accept the following optional flag.  It is listed
   in the command descriptions and described in detail here:

       Prints a command's online help message on the standard output
       stream. Do not combine this flag with any of the command's other
       options; when it is provided, the command interpreter ignores all
       other options, and only prints the help message.


   To issue most fstrace commands, the issuer must be logged on as the
   local superuser "root" on the machine that is generating the trace log.

Free Software

Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.

Free Books

The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.
