问题解答

基于严重性的陷阱是一种根据已引发的EMS事件的严重性发出的陷阱类型。 

注:

  • EMS会为每个事件配置一个陷阱类型。
  • ONTAP有三种陷阱类型: StandardSeverity-basedBuilt-in。 
    • Standard:在RFC中定义
    • Built-in:  特定于事件的NetApp企业陷阱
    • Severity-based:以上除外
  • Severity-based 发生与事件筛选器设置匹配的事件时、将激发陷阱。
  • ONTAP系统定义的筛选器 default-trap-events 具有以下筛选器

Filter Name Rule    Rule    Message Name       SNMP Trap Type  Severity
       Position Type
----------- -------- --------- ---------------------- --------------- --------
default-trap-events
       1     include   *            *         EMERGENCY, ALERT
       2     include   callhome.*        *         ERROR
       3     include   *            Standard, Built-in
                                    *
       4     exclude   *            *         *

  • 此筛选器表示:
  1. 排除所有事件
  2. 包括所有 紧急、警报 事件
  3. 包括所有 以开头的错误事件callhome.
  4. 包括所有 StandardBuilt-in 事件
  • 如果 callhome.*  引发了具有错误严重性的事件、紧急事件或警报事件,并且陷阱类型既不是 “标准 ”也不是“内置  ”,EMS将根据引发的每个事件的严重性按基于严重性的陷阱发出通知。
