This adds a new counter tool to be able to test various watch events. A flexible watch array can be populated from command line, each field may be tuned with a dedicated command line sub-option in "--watch" string. Several watch events can be defined, each can have specific watch options, by using "--watch <watch 1 options> --watch <watch 2 options>". Watch options is a comma separated list. It also comes with a simple default watch (to monitor overflow/underflow events), used when no watch parameters are provided. It's equivalent to: counter_watch_events -w comp_count,scope_count,evt_ovf_udf The print_usage() routine proposes another example, from the command line, which generates a 2 elements watch array, to monitor: - overflow underflow events - capture events, on channel 3, that reads read captured data by specifying the component id (capture3_component_id being 7 here).
