<P>Introduction to the <B>fstrace</B> command suite
|
||
|
|
<P><STRONG>Description</STRONG>
|
||
|
|
<P>The commands in the <B>fstrace</B> 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 <B>ls</B>
|
||
|
|
command.
|
||
|
|
<P>The <B>fstrace</B> command interpreter defines an extensive set of
|
||
|
|
Cache Manager operations as the <B>cm</B> <I>event set</I>.
|
||
|
|
When the event set is activated, the Cache Manager writes a message to the
|
||
|
|
<B>cmfx</B> <I>trace log</I> 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 <I>IBM AFS Administration
|
||
|
|
Guide</I>.
|
||
|
|
<P>There are several categories of commands in the <B>fstrace</B> command
|
||
|
|
suite:
|
||
|
|
<UL>
|
||
|
|
<P><LI>Commands to administer or display information about the trace log:
|
||
|
|
<P><B>fstrace clear</B>, <B>fstrace lslog</B>, <B>fstrace
|
||
|
|
setlog</B>
|
||
|
|
<P><LI>Commands to set or display the status of the event set:
|
||
|
|
<P><B>fstrace lsset</B> and <B>fstrace setset</B>
|
||
|
|
<P><LI>A command to display the contents of the trace log: <B>fstrace
|
||
|
|
dump</B>
|
||
|
|
<P><LI>Commands to obtain help: <B>fstrace apropos</B> and <B>fstrace
|
||
|
|
help</B>
|
||
|
|
</UL>
|
||
|
|
<P><STRONG>Options</STRONG>
|
||
|
|
<P>All <B>fstrace</B> commands accept the following optional flag.
|
||
|
|
It is listed in the command descriptions and described in detail here:
|
||
|
|
<A NAME="IDX5027"></A>
|
||
|
|
<DL>
|
||
|
|
<P><DT><B>-help
|
||
|
|
</B><DD>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.
|
||
|
|
</DL>
|
||
|
|
<P><STRONG>Privilege Required</STRONG>
|
||
|
|
<P>To issue most <B>fstrace</B> commands, the issuer must be logged on as
|
||
|
|
the local superuser <B>root</B> on the machine that is generating the
|
||
|
|
trace log.
