CIMON

CIMON (Configurable Integrated Monitoring system) is a monitoring service which provides a layer of abstraction to support monitoring and context-aware applications. Android applications can use the CIMON API to easily register monitors, and the CIMON monitoring service will integrate each of these requests to meet their needs efficiently.

There are a variety of metrics supported related to system status and activity, sensors, and user activity. CIMON also supports registering of complex monitors which are represented by boolean expressions. These monitors can notify applications when a particular event or condition has occurred.

In addition to the monitoring service, there is an administration app, shown in the screenshots, which allows you to easily add new monitors.

For more complete information, check out the project homepage. The complete JavaDoc is available at the homepage. The source code is freely available and can be extended to include additional metrics.
