NAME

No::Worries::Syslog - syslog handling without worries

SYNOPSIS

  use No::Worries::Syslog qw(syslog_open syslog_close syslog_info);

  # setup/open syslog
  syslog_open(ident => "progname", facility => "daemon");

  # report an informational message
  syslog_info("foo is %s", $foo);

  # close syslog
  syslog_close();

DESCRIPTION

This module eases syslog handling by providing convenient wrappers around standard syslog functions.

The functions provide a thin layer on top of Sys::Syslog to make it easier and safer to use. All the functions die() on error and the strings passed to syslog will always be sanitized.

FUNCTIONS

This module provides the following functions (none of them being exported by default):

syslog_open([OPTIONS])

open a "connection" to syslog using Sys::Syslog's openlog(); supported options

• facility: corresponding to openlog()'s eponymous argument

• ident: corresponding to openlog()'s eponymous argument

• option: corresponding to openlog()'s eponymous argument

syslog_close()

close a "connection" to syslog using Sys::Syslog's closelog()

syslog_sanitize(STRING)

sanitize the given string so that it can safely be given to syslog(): UTF-8 encode wide characters, trim trailing spaces, replace tabs by spaces, URI escape non-printable characters and truncate if too long

syslog_debug(MESSAGE)

report a sanitized debugging message to syslog (with LOG_DEBUG priority and [DEBUG] prefix)

syslog_debug(FORMAT, ARGUMENTS...)

idem but with sprintf()-like API

syslog_info(MESSAGE)

report a sanitized informational message to syslog (with LOG_INFO priority and [INFO] prefix)

syslog_info(FORMAT, ARGUMENTS...)

idem but with sprintf()-like API

syslog_warning(MESSAGE)

report a sanitized warning message to syslog (with LOG_WARNING priority and [WARNING] prefix)

syslog_warning(FORMAT, ARGUMENTS...)

idem but with sprintf()-like API

syslog_error(MESSAGE)

report a sanitized error message to syslog (with LOG_ERR priority and [ERROR] prefix)

syslog_error(FORMAT, ARGUMENTS...)

idem but with sprintf()-like API

log2syslog(INFO)

No::Worries::Log handler to send information to syslog; this is not exported and must be called explicitly

GLOBAL VARIABLES

This module uses the following global variables (none of them being exported):

$MaximumLength

maximum length of a message given to syslog (default: 1000)

$SplitLines

true if multi-line messages should be logged as separate syslog messages (default: true)
