Monitoring performance

There are various methods to monitor the performance of the IoT Gateway and its services. Apart from monitoring performance counters provided by the operating system, you can also monitor event logs and sniffer output, if enabled.

Monitoring event logs

In the application data folder, a subfolder called Events is created. In it, XML files will be output when events are logged from anywhere in the system. Old XML files will be deleted automatically. The XML files reference XSL transforms in the Transforms subfolder to the application data folder. This makes it possible to view finished XML files in browsers in a user-friendly manner.


Events are also persisted in the object database. These events can be searched and accessed via the XMPP interface.


You can output events from your code by accessing the static Log class defined in Waher.Events.
