I was hoping someone can point me in the right direction. I'm trying to filter out errors from a web log- any lines with ERROR in it. I know I could simply use the grep command to do this. However, there are times when a stack trace follows the error line. I would like to capture these lines as well. Here is a snippet of the web log:
I was thinking of incorporating some conditional logic, where we filter out lines with ERROR and also any lines thereafter that start with a white space (the stack trace lines start with a tab). Couldn't figure out how to tie that in with grep.
I am using gdb to examine a core file but the output contains only the method addresses in hex.
Is there anyway to translate these addresses to a human-readable form? :confused: (0 Replies)
I am trying to print a stack trace programatically using backtrace and backtrace_symbols.
The problem is that the stack being printed in a mangled format. Is there a way to get the output in more of a human readable form?

Hi all,
One of our programs written in Java, produced this logfile. This job runs 48 threads and only one thread failed with this error. The code is a blackbox(external product), so cant look at the source code. From what I can infer from the log, the job was trying to write the log messages into... (9 Replies)
I'm on solaris 8. I need to check the stack trace inside my C program. I don't have printstack or walkstack. I tested getcontext and it works. But how do I get the symbols from "stack_t" ? Help please. Many thanks! (4 Replies)

Hi All,
I am trying to debug my core file using kdb.

Hi All
Thought it would be kind of fun to implement a stack trace for a shell script that calls functions within a sub shell. This is for bash under Linux and probably not portable -
#! /bin/bash
error_exit()

echo $1

I have a C program which is running as daemon and has some threads.
The program is running on dual core cpu and it may happen that different threads may run on different cpu core.
The problem is sometimes it crashes with some heap memory corruption probably between threads.

I want the developers to get a mail with Java stack traces on a daily bases. When something is flaged as known issue and will get a fix but mean while this does not need to get sent each dayl. This is what I got so far. It's a bash script that runs some AWK in it.

log::log4perl::level
Level(3) User Contributed Perl Documentation Level(3)NAME
Log::Log4perl::Level - Predefined log levels
SYNOPSIS
use Log::Log4perl::Level;
print $ERROR, "
";
# -- or --
use Log::Log4perl qw(:levels);
print $ERROR, "
";
DESCRIPTION
"Log::Log4perl::Level" simply exports a predefined set of Log4perl log levels into the caller's name space. It is used internally by
"Log::Log4perl". The following scalars are defined:
$OFF
$FATAL
$ERROR
$WARN
$INFO
$DEBUG
$TRACE
$ALL
"Log::Log4perl" also exports these constants into the caller's namespace if you pull it in providing the ":levels" tag:
use Log::Log4perl qw(:levels);
This is the preferred way, there's usually no need to call "Log::Log4perl::Level" explicitely.
The numerical values assigned to these constants are purely virtual, only used by Log::Log4perl internally and can change at any time, so
please don't make any assumptions.
If the caller wants to import these constants into a different namespace, it can be provided with the "use" command:
use Log::Log4perl::Level qw(MyNameSpace);
After this $MyNameSpace::ERROR, $MyNameSpace::INFO etc. will be defined accordingly.
Numeric levels and Strings
Level variables like $DEBUG or $WARN have numeric values that are internal to Log4perl. Transform them to strings that can be used in a
Log4perl configuration file, use the c<to_level()> function provided by Log::Log4perl::Level:
use Log::Log4perl qw(:easy);
use Log::Log4perl::Level;
# prints "DEBUG"
print Log::Log4perl::Level::to_level( $DEBUG ), "
";
To perform the reverse transformation, which takes a string like "DEBUG" and converts it into a constant like $DEBUG, use the to_priority()
function:
use Log::Log4perl qw(:easy);
use Log::Log4perl::Level;
my $numval = Log::Log4perl::Level::to_priority( "DEBUG" );
after which $numval could be used where a numerical value is required:
Log::Log4perl->easy_init( $numval );
