amsbenchs(1) Asynchronous Message Service (AMS) benchmarking driver


amsbenchs count size


amsbenchs is a test program that simply publishes count messages of size bytes each on subject ``bench'', then waits while all published messages are transmitted, terminating when the user uses ^C to interrupt the program. The remaining number of messages to be published in the test is written into the first four octets of each message.

amsbenchs will register as an application module in the root unit of the venture identified by application name ``amsdemo'' and authority name ``test''. A configuration server for the local continuum and a registrar for the root unit of that venture (which may both be instantiated in a single amsd daemon task) must be running in order for amsbenchs to commence operations.


amsbenchs failed, for reasons noted in the ion.log file.

A MIB initialization file with the applicable default name (see amsrc(5)) must be present.


No environment variables apply.
