Instrumentation Signal-Method Mapping

Instrument methods get automatically hooked up to signals based on their names. Mostly, the method name correponds to the name of the signal, however there are a few convienience aliases defined (listed first) to make easier to relate instrumenation code to the workload execution model.

method name	signal
initialize	run-init-signal
setup	successful-workload-setup-signal
start	before-workload-execution-signal
stop	after-workload-execution-signal
process_workload_result	successful-iteration-result-update-signal
update_result	after-iteration-result-update-signal
teardown	after-workload-teardown-signal
finalize	run-fin-signal
on_run_start	start-signal
on_run_end	end-signal
on_workload_spec_start	workload-spec-start-signal
on_workload_spec_end	workload-spec-end-signal
on_iteration_start	iteration-start-signal
on_iteration_end	iteration-end-signal
before_initial_boot	before-initial-boot-signal
on_successful_initial_boot	successful-initial-boot-signal
after_initial_boot	after-initial-boot-signal
before_first_iteration_boot	before-first-iteration-boot-signal
on_successful_first_iteration_boot	successful-first-iteration-boot-signal
after_first_iteration_boot	after-first-iteration-boot-signal
before_boot	before-boot-signal
on_successful_boot	successful-boot-signal
after_boot	after-boot-signal
on_spec_init	spec-init-signal
on_run_init	run-init-signal
on_iteration_init	iteration-init-signal
before_workload_setup	before-workload-setup-signal
on_successful_workload_setup	successful-workload-setup-signal
after_workload_setup	after-workload-setup-signal
before_workload_execution	before-workload-execution-signal
on_successful_workload_execution	successful-workload-execution-signal
after_workload_execution	after-workload-execution-signal
before_workload_result_update	before-iteration-result-update-signal
on_successful_workload_result_update	successful-iteration-result-update-signal
after_workload_result_update	after-iteration-result-update-signal
before_workload_teardown	before-workload-teardown-signal
on_successful_workload_teardown	successful-workload-teardown-signal
after_workload_teardown	after-workload-teardown-signal
before_overall_results_processing	before-overall-results-process-signal
on_successful_overall_results_processing	successful-overall-results-process-signal
after_overall_results_processing	after-overall-results-process-signal
on_error	error_logged
on_warning	warning_logged

The names above may be prefixed with one of pre-defined prefixes to set the priority of the Instrument method realive to other callbacks registered for the signal (within the same priority level, callbacks are invoked in the order they were registered). The table below shows the mapping of the prifix to the corresponding priority:

prefix	priority
very_fast_	20
fast_	10
normal_	0
slow_	-10
very_slow_	-20
