NAME Mojo::Log::JSON - Simple JSON logger SYNOPSIS use Mojo::Log::JSON; # Log to STDERR my $logger = Mojo::Log::JSON->new; # Customize log file location, minimum log level and default fields my $logger = Mojo::Log::JSON->new( # path => '/var/log/mojo.log', level => 'warn', default_fields => { # default fields added to log app_name => "MyApp", # either scalar random_thing => sub { rand() }, # or codref, }, include_level => 1, # default - include 'level' key in output ); # To add an extra default field $logger->default_fields->{foo} = "bar"; # Log messages - debug, info, warn, error, fatal (same as Mojo::Log) $logger->debug( "A simple string" ); $logger->debug( "A", "message", "over", "multiple", "lines" ); $logger->debug( { message => "A data structure", abc => "123" } ); # The above examples would generate something like the following: {"datetime":"2014-03-13 13:15:44","foo":"bar","level":"debug","message":"A simple string"} {"datetime":"2014-03-13 13:15:45","foo":"bar","level":"debug","message":"A\nmessage\nover\nmultiple\nlines"} {"datetime":"2014-03-13 13:15:46","abc":"123","foo":"bar","level":"debug","message":"A data structure"} # To not include 'level' set an undefined default_fields key either in the # constructure or as follows: $logger->default_fields->{level} = undef; DESCRIPTION Mojo::Log::JSON is a simple JSON logger for Mojo projects. It logs a JSON object (hashref) per log message. Each object occupies a single line to allow easy parsing of the log output. The key "level" is always added to the data structure, with the value set to the level of the log message being emitted. To omit this, set "include_level" to a false value. By default the key "datetime" is also added to the data structure with a value of the current time in ISO 8601 format. This can be removed or other fields can be added via the "default_fields" attribute. ATTRIBUTES All of the attributes of Mojo::Log are present, plus the following additional attributes. codec Pass in a JSON object to override the default JSON formatting settings. default_fields Hashref of key/value pairs to add to the data structure. Can be overwritten by values in the log message METHODS Mojo::Log::JSON inherits all methods from Mojo::Log.
