NAME

Mojo::Log::JSON::LogStash - Simple JSON logger to produce LogStash format logs

SYNOPSIS

    package MyApp;

    use Mojo::Log::JSON::LogStash;

    sub startup {
        my $self = shift;

        ...

        open my $handle, '|-',
            'logstash-forwarder -config=/path/to/logstash-forwarder-config.conf'
            or die "can't run logstash-forwarder: $!";

        my $logger = Mojo::Log::JSON::LogStash->new( handle => $handle );

        $logger->default_fields->{foo} = "bar";    # add extra default field

        ...
    }

    # Log messages - debug, info, warn, error, fatal (same as Mojo::Log)

    $log->debug( "A simple string" );
    $log->debug( "A", "message", "over", "multiple", "lines" );
    $log->debug( { message => "A data structure", foo => "bar" } );

    # The above examples would generate something like the following:
    {"@timestamp":"2014-03-13T13:15:44.005134Z","@version":1,"level":"debug","message":"A simple string"}
    {"@timestamp":"2014-03-13T13:15:45.123565Z","@version":1,"level":"debug","message":"A\nmessage\nover\nmultiple\nlines"}
    {"@timestamp":"2014-03-13T13:15:46.863454Z","@version":1,"foo":"bar","level":"debug","message":"A data structure"}

DESCRIPTION

Mojo::Log::JSON::LogStash is a simple subclass of Mojo::Log::JSON to produce JSON logs suitable for LogStash.

The key level is always added to the data structure, with the value set to the level of the log message being emitted.

The required LogStash keys @timestamp and @version are also added to the data structure. @timestamp is set with a value of the current time in UTC in ISO 8601 format, with microseconds.

These can be overridden or other fields added via the default_fields attributes.
