Logger
1.6.5The Glue42 Logging API enables JavaScript applications to create a hierarchy of sub-loggers mapped to application components where you can control the level of logging for each component. You can also route the output of log messages (depending on the logging level) to a variety of targets:
- the developer console;
- an external output - usually a rolling file on the desktop, but actually any target the
log4netlibrary supports; - the Glue42 Desktop Metrics bus;
- the Glue42 Notification Service;
The last three targets give you the ability to:
- connect to a remote desktop and pull the application log files using the Interop Viewer;
- connect to the Metrics bus and monitor the application in real time, or record log messages routed to a metrics storage in a Cassandra database for later analysis;
- raise notifications which can be displayed via a customizable UI on the user's desktop;
