NAME
Paranoid::Log::File - File Logging Functions
VERSION
$Id: lib/Paranoid/Log/File.pm, 2.10 2022/03/08 00:01:04 acorliss Exp $
SYNOPSIS
use Paranoid::Log;
startLogger('events', 'File', PL_DEBUG, PL_GE,
{
file => '/var/log/events.log',
mode => O_TRUNC | O_CREAT | O_RDWR,
perm => 0600,
syslog => 1,
});
DESCRIPTION
This provides a mechanism to log to log files. It will log arbitrarily long text, but also provides a syslog mode which limits log lines to 2048 and precedes text with the standard syslog preamble (date/time, host, process name/PID).
The only mandatory option is the file key/value pair. This module leverages Paranoid::IO's popen.
mode defaults to O_CREAT | O_APPEND | O_WRONLY.'
perm defaults to 0666 ^ UMASK
syslog defaults to false. Enabling it causes every line to be formatted akin to syslog, along with the 2048 byte limit on messages.
OPTIONS
The options recognized for use in the options hash are as follows:
Option Value Description
-----------------------------------------------------
file string file name of log file
mode integer file mode to open with
perm integer file permissions of newly
created log files
syslog boolean enable syslog-style format

BUGS AND LIMITATIONS
This isn't a high performance module when dealing with a high logging rate with high concurrency. This is due to the advisory locking requirement and the seeks to the end of the file with every message. This facility is intended as a kind of lowest-common denominator for programs that need some kind of logging capability.
