NAME
Log::JSON - Log data to a file as JSON
SYNOPSIS
use Log::JSON;
my $logger = Log::JSON->new(
file => '/path/errorlog.json', # required
date => 1, # optional
remove_newlines => 1, # optional
);
$logger->log(a => 1, b => 2);
# '/path/errorlog.json' now contains:
# {"__date":"2010-03-28T23:15:52Z","a":1,"b":1}
DESCRIPTION
This module logs a hash to a file as JSON. The keys are printed in sorted order.
Often log files have several raw numbers and strings whose meaning is not immediately clear. With JSON formatted text in your log files, a human can open the file and quickly decipher the content because each piece of information is labeled.
Using JSON also means log files are easy to parse and the data structures can be easily revived.
ATTRIBUTES
date
Adds an __date field to your json. The '__' part ensures the date is the first information logged to each line when the keys are sorted.
file
The name of the file to log data to
remove_newlines
This boolean is set to true by default. It means your json data structures will be logged entirely on one line.
METHODS
log(%hash)
Appends %hash to a file as JSON. The keys are sorted when the hash is converted to JSON.
BUGS
This should probably should have been a Log::Dispatch plugin.
SEE ALSO
Log::Message::Structured, Log::Structured, Log::Sprintf
