LNAV -- The Logfile Navigator
|
||
|
|
=============================
|
||
|
|
|
||
|
|
The log file navigator, lnav, is an enhanced log file viewer that
|
||
|
|
takes advantage of any semantic information that can be gleaned from
|
||
|
|
the files being viewed, such as timestamps and log levels. Using this
|
||
|
|
extra semantic information, lnav can do things like interleaving
|
||
|
|
messages from different files, generate histograms of messages over
|
||
|
|
time, and providing hotkeys for navigating through the file. It is
|
||
|
|
hoped that these features will allow the user to quickly and
|
||
|
|
efficiently zero in on problems.

Prerequisites
|
||
|
|
-------------
|
||
|
|
|
||
|
|
Lnav requires the following software packages:
|
||
|
|
|
||
|
|
* libpcre - The Perl Compatible Regular Expression (PCRE) library.
|
||
|
|
* sqlite - The SQLite database engine.
|
||
|
|
* ncurses - The ncurses text UI library.
|
||
|
|
* readline - The readline line editing library.
|
||
|
|
* zlib - The zlib compression library.
|
||
|
|
* bz2 - The bzip2 compression library.
|
||
|
|
|
||
|
|
|
||
|
|
Installation
|
||
|
|
------------
|
||
|
|
|
||
|
|
Lnav follows the usual GNU style for configuring and installing software:
|
||
|
|
|
||
|
|
$ ./configure
|
||
|
|
$ make
|
||
|
|
$ sudo make install
|
||
|
|
|
||
|
|
|
||
|
|
Using
|
||
|
|
-----
|
||
|
|
|
||
|
|
The only file installed is the executable, "lnav". You can execute it
|
||
|
|
with no arguments to view the default set of files:
|
||
|
|
|
||
|
|
$ lnav
|
||
|
|
|
||
|
|
You can view all the syslog messages by running:
|
||
|
|
|
||
|
|
$ lnav /var/log/messages*
|
||
|
|
|
||
|
|
|
||
|
|
