对SDH专业告警的关联进行了分析,完成了这些告警之间的关系显示,成功地应用于中国电信网络监控部。我们通过集中告警系统将告警采集上来,并通过资源系统将所得到的告警相关联,找到其中的主从关系,并将这种关系以SQL语句的方式记录到数据库中供集中告警系统调用,最终在集中告警客户端上实现关联关系的呈现,从而使网管人员可以在极短时间内判断出155M以上级别告警影响了多少个2M,这些2M上都承载了哪些业务。 The association of SDH professional alarms was analyzed, the relationship between these alarms was completed and successfully applied to China Telecom Network Monitoring Department. We collected the alarm through the centralized alarm system and correlated the obtained alarms through the resource system to find the master-slave relationship and recorded the relationship to the database by the SQL statement for centralized alarm system call. Finally, So as to enable network administrators to determine in a very short period of time how many 2Ms are affected by alarms of 155M or higher and which services are carried by these 2Ms.
