Management Utilities

The essential management utilities offered by the ChorusOS operating system include:

• Netboot: Boots the ChorusOS operating system remotely using TFTP, when the target does not provide an embedded boot facility.

• Default Console: Directs all console I/O to a local display or to a remote host via a serial line.

• Remote Shell: Executes commands remotely on the target from the host. In particular, this feature allows applications to be loaded dynamically.

• Resource Status: Lists the current status of all operating system resources, for example, actors, threads and memory.

• Logging (Feature name:LOG): Logs operating system events as they occur on the target.

• Monitoring (Feature name:MON). Monitors operating system objects, so that user defined routines are called when certain operations are performed on specified objects.

• Profiling : Runs profiling sessions on system applications.

• Benchmarking: Benchmarks the operating system.

• Watchdog Timer: Monitors the ChorusOS operating system and, should a crash occur, the timer expires. Diagnostic information is then collected, if possible, as described in the "System Crash and the SYSTEM_DUMP Utility". This implementation of the WDT API supports a maximum of one watchdog timer.

• Black Box: Comprises a set of microkernel ring buffers to provide real time collection and storage of historical event information leading up to a system failure.
