History PM data |
For each performance parameter of each performance monitoring entity, the NE provides two types of registers:(1) 15-minute register: accumulating the performance event data within 15 minutes; (2) 24-hour register: accumulating the performance event data within 24 hours. Each type of register can be further divided as follows:(2) Current register: The current 15-minute register or current 24-hour register (only one for each) is applied to collect the performance data in the current monitoring period. It changes within the monitor period. (2) History register: The 15-minute history register (16 pieces) or 24-hour history register (6 pieces) is a first-in-first-out queue. If the history registers are full, the register storing the earliest history data will be overwritten. The performance data stored in the history register and the auto-report performance data saved on the NM are called history performance data in a unified way. |
