RB_free_bottom
water mark

 

Description:  The lowest number of free request blocks reached during processing.

Usage:  Use this element in conjunction with the fcm_num_rqb configuration parameter to determine the maximum request block utilization. If RB_free_bottom is low, you should increase fcm_num_rqb to ensure that operations do not run out of request blocks. If RB_free_bottom is high, you can decrease fcm_num_rqb to conserve system resources.
