logtool(1)logtool(1)NAMElogtool - 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 multi‐
log 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 follow‐
ing: 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
/usr/local/etc/logtool/logtool.conf
-i [/path/includefile]
Allows you to specify an alterate file containing regex's for
inclusion [default=/usr/local/etc/logtool/include]
-e [/path/excludefile]
Allows you to specify an alternate file containing regex's for
exclusion [default=/usr/local/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
/usr/local/etc/logtool/logtool.conf
The config file should be commented to the point of being self-docu‐
menting, so we will not comment very extensively on it here. Suffice
to say, this is the place where you should configure 99% of your run‐
time 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).
SEE ALSOregex(7) for help with constructing regular expressions for the
include/exclude/colors files. If you find no regex manual on your sys‐
tem, try 'apropos regex' and see what you get, or as a last ditch, 'man
grep' should at least point you in the right direction.
You can also find a somewhat better bit of documentation in the
textfile 'logtool.txt' (usually in the /usr/doc/, /usr/share/doc/ or
similar tree on most Linux distributions). If you don't know where to
look, you can probably find it by typing 'locate logtool.txt' at the
command line.
