== DESCRIPTION:

Lwes based ruby logger for real-time logging.

== FEATURES:

• Send logging udp events with lwes.

• Optionally also log to a local file.

== SYNOPSIS:

require 'lwes_logger'

logger = LwesLogger.new '127.0.0.1', :log_device => "optional_backup_logfile.logs"

logger.namespace = "MyApp::Logs"

logger.meta_event.merge! :app_name => "myapp", :user => whoami

logger.debug "This is a debug log event" logger.error "OH NOES!"

Will produce logs in the optional_backup_logfile.logs file and will generate the following Lwes events:

System::Startup[3] { SenderPort = 64885; ReceiptTime = 1286495516997; SenderIP = 127.0.0.1; } MyApp::Logs::Full[12] { SenderPort = 64885; message = This is a debug log event; progname = This is a debug log event; event_id = MyApp::Logs::Debug-3bd9c9d2-d272-11df-b9a6-00254bfffeb1; app_name = myapp; user = system_user; ReceiptTime = 1286495519612; SenderIP = 127.0.0.1; timestamp = Oct 07 16:51:59; hostname = example.com; severity = DEBUG; pid = 70884; } MyApp::Logs::Debug[12] { SenderPort = 64885; message = This is a debug log event; progname = This is a debug log event; event_id = MyApp::Logs::Debug-3bd9c9d2-d272-11df-b9a6-00254bfffeb1; app_name = myapp; user = system_user; ReceiptTime = 1286495519612; SenderIP = 127.0.0.1; timestamp = Oct 07 16:51:59; hostname = example.com; severity = DEBUG; pid = 70884; } MyApp::Logs::Full[12] { SenderPort = 64885; message = OH NOES!; progname = OH NOES!; event_id = MyApp::Logs::Error-3a38b5f6-d273-11df-b9a6-00254bfffeb1; app_name = myapp; user = system_user; ReceiptTime = 1286495519612; SenderIP = 127.0.0.1; timestamp = Oct 07 16:51:59; hostname = example.com; severity = ERROR; pid = 70884; } MyApp::Logs::Error[12] { SenderPort = 64885; message = OH NOES!; progname = OH NOES!; event_id = MyApp::Logs::Error-3a38b5f6-d273-11df-b9a6-00254bfffeb1; app_name = myapp; user = system_user; ReceiptTime = 1286495519612; SenderIP = 127.0.0.1; timestamp = Oct 07 16:51:59; hostname = example.com; severity = ERROR; pid = 70884; } System::Shutdown[7] { freq = 145; SenderPort = 64885; seq = 0; ReceiptTime = 1286495661890; total = 0; SenderIP = 127.0.0.1; count = 0; }

Notice that for convenience, logs events are broadcast to both the Full and Severity (e.g. Debug) events. You can change the name of the full logs by setting the full_logs_event attribute to a string, or turn full logs off completely by setting it to false:

logger.full_logs_event = "OtherFullLogs" logger.full_logs_event = false

Alternatively, if you'd rather only have full logs you can assign the full_logs_only attribute:

logger.full_logs_only = true
