total_q_under_processor_handle - number of queues in error state due to an
async error or errored command.

send_queue_priority_update_flow - number of QP/SQ priority/SL update
events.

cq_overrun - number of times CQ entered an error state due to an
overflow.

async_eq_overrun -number of time an EQ mapped to async events was
overrun.

comp_eq_overrun - number of time an EQ mapped to completion events was
overrun.

quota_exceeded_command - number of commands issued and failed due to quota
