logtool - Online in the Cloud

PROGRAM:

NAME

logtool - parse and filter syslog files

SYNOPSIS

(stdout) | logtool -[args]

Logtool is a command line program that will parse logfiles into a more palatable format.
It will take anything resembling a syslog or multilog file, as well as unformatted ASCII,
and crunch it into one of the following formats for your viewing pleasure:

ANSI (colorized for easy "at a glance" viewing)

ASCII (e-mail reports/term's w/o color)

CSV (spreadsheet/database imports)

HTML (for generating web pages)

RAW (for no good reason)

OPTIONS

-o [ ANSI | ASCII | CSV | HTML | RAW ]
Allows you to specify the output format to be one of the following: ANSI (default),
ASCII, CSV, HTML, RAW. Options are not case sensitive (ie: -o CSV and -o csv should
yield the same results)

-t [ long | short ]
Allows you to specify the time display format to be one of the following: (Long
[default]) Mon Dy HH:MM:SS or (Short) HH:MM

-b Causes logtool to beep on RED events (ANSI output only). This is usefull when you
want to monitor a logfile on an ongoing basis, and wish to have your terminal beep
whenever something out of the ordinary happens.

-s Causes logtool to not display the syslog "source" field

-p Causes logtool to not display the "program" field

-c [/path/config.file]
Allows you to specify a config file other than the default /etc/logtool/logtool.conf

-i [/path/includefile]
Allows you to specify an alterate file containing regex's for inclusion
[default=/etc/logtool/include]

-e [/path/excludefile]
Allows you to specify an alternate file containing regex's for exclusion
[default=/etc/logtool/exclude]

-n Causes logtool to skip any attempts to resolve IP->Hostname by the various modules
(handy when your DNS is down temporairly).

-v Set logtool to operate in verbose mode (does nothing currently)

-V Causes logtool to print it's version information and exit

-h Display the help message

SUGGESTED USAGE(S)

As a 'live' logfile monitoring tool:
tail -f /var/log/messages | logtool -o ANSI -b

To generate colorized webpages of logfiles:
cat /var/log/messages | logtool -o HTML > /home/httpd/html/logs/messages.html

To generate reports via a cronjob:
retail /var/log/messages | logtool -o ASCII | mail -s "Daily report"
someuser@somedomain.ext

CONFIG FILE

/etc/logtool/logtool.conf

The config file should be commented to the point of being self-documenting, so we will not
comment very extensively on it here. Suffice to say, this is the place where you should
configure 99% of your runtime options for logtool. You may also have a collection of
different default configurations, and select amongst them by the '-c' option of logtool.

AVAILABILITY

Logtool is known to compile/run on all UNIX flavors using a 2.95.x GNU C Compiler, the GNU
Make utility, and a proper ANSI C library (glibc is recommended, but not required).
Specific reports of success include FreeBSD, OpenBSD, Solaris, SunOS, AIX, SCO, and of
course, any known flavor of Linux (including at least 2 embedded system variants).
