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 IBM AFS 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, 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.
