The following ibdiagnet options can be used to dump SHARP Trees configuration and SHARP traffic counters.
Parameter | Description |
--sharp | Collects SHARP Trees configuration and dump to ibdiagnet2.sharp & ibdiagnet2.sharp_an_info.
|
--sharp_control_version <0|1|2> | Checks and dumps only SHARP nodes with the specified version (default 0):
|
--sharp_opt <\[csc,\]\[dsc,\]> | Comma separated SHARP options once "--sharp" option is selected:
|
