解答

OnCommand Unified Manager ( DFM )使用五种不同的方法进行标识 主机是否已关闭

  1. echo
  2. HTTP
  3. SNMP
  4. NDMP
  5. echo_snmp (默认)

主机关闭监控器运行的默认行为是结合使用 ICMP 回显和 snmpwalk 执行 ping 操作。OnCommand Unified Manager ( DFM )将重试每种方法预先配置的次数,并且超时情况各不相同,如以下输出所示。
 

pingMonInterval 00 : 01 : 00
hostPingMethod echo_snmp
pingMonTimeout 3
pingMonRetryDelay 3
monSNMPTimeout 60
monSNMPR4.

默认情况下, OnCommand Unified Manager ( DFM )每分钟执行一次此检查。超时和重试值以秒为单位。增加这些值将延迟 OnCommand Unified Manager ( DFM )假定主机关闭之前的时间。控制器的状态会记录在 pingmon.log 中,并显示 unknown , up 或 down 。它将记录状态的更改,例如从上到下,从下到上,从未知到上等。
