This utility is intended to assist in the analysis of large debug output
files generated with -ORBDebuglevel 10. The utility summarizes thread,
connection, and invocation details for a collection of related processes.
This is a work in progress. It currently is limited to parsing logs of
IIOP based apps only.
The executable is installed as $ACE_ROOT/bin/tao_logWalker.
The command line options are:
-t <version> where <version> represents a TAO minor version
number, currently only 1.5 and 1.6 are supported.
As variations in logfile output bound to version
are found, this option will expand and may include
micro release numbers as well. Default is 1.6.
-o <filename> redirects the output to the named file rather than
standard out.
-d <directory> breaks the output into multiple files under the
named directory. The directory will be created if
it does not exist. -o and -d are mutually exclusive.
-p <name=value> allows the tagging of processes participating in
a logged run, but for which no log file exists. The
name in this case is some alias which will appear in
the output, and value is the TCP endpoint used by
the phantom process.
-a <name=value> allows for substitution of addresses. Some endpoints
may be logged using a hostname, while other instances
may appear as an IP address. This is a simple means
of substituting one for the other to improve the
recognition of a peer process.
-m <filename> read argument from the named manifest file. For
repeated analysis of may perhaps distributed log files,
use a manifest file to minimize keying in long command
lines. Each line of the file contains one full argument.
[alias=]logfile provide as many log files as needed. The optional
alias gives a way to assign a useful name to the process
that generated the log output in the file. If many
processes shared a logfile so that their output is
comingled or consecutive, each process instance will be
given an indexed alias such as alias_1, alias_2, etc.
Below is a sample output resulting from a run of tests/Hello, which can be
reproduced by running: ./tao_logWalker -m hello.mft
