Paranoid::Log::Buffer - Log Buffer Functions

VERSION

$Id: Buffer.pm,v 0.83 2010/06/03 19:03:46 acorliss Exp $

SYNOPSIS

  use Paranoid::Log;
  
  enableFacility('events', 'buffer', 'debug', '+');
  enableFacility('more-events', 'buffer', 'debug', '+', 100);

  @messages = Paranoid::Log::Buffer::dump($name);

DESCRIPTION

This module implements named buffers to be used for logging purposes. Each buffer is of a concrete size (definable by the developer) with a max message length of 2KB. Each message is stored with a timestamp. Once the buffer hits the maximun number of entries it begins deleting the oldest messages as the new messages come in.

Buffers are created automatically on the fly, and messages trimmed before being stored.

With the exception of the dump function this module is not meant to be used directly. Paranoid::Log should be your exclusive interface for logging.

When enabling a buffer facility with Paranoid::Log you can add one integral argument to the call. That number defines the size of the log buffer in terms of number of entries allowed.

NOTE: Buffers are maintained within process memory. If you fork a process from a parent with a log buffer each copy will maintain its own entries.

SUBROUTINES/METHODS

NOTE: Given that this module is not intended to be used directly nothing is exported.

init

log

remove

Paranoid::Log::Buffer::dump

  @entries = Paranoid::Log::Buffer::dump($name);

This dumps all current entries in the named buffer. Each entry is an array reference to a two-element array. The first element is the timestamp of the message (in UNIX epoch seconds), the second the actual message itself.
