service, which replies immediately to confirm it is running. This method is
useful when ICMP is blocked on routers between the source and target.
● Application Monitoring—If you select the Application Monitoring option,
the fields in Application Monitoring Settings area will be enabled.
Note:
In order to use Application Monitoring, the monitored servers must be running
Storage Mirroring Recover version 5.2 or later.
Application monitoring is not available when dealing with a cluster.
4. Configure how long to wait after a source failure to initiate failover. The amount of
time before failover begins is calculated by multiplying the Monitor Interval by the
Failure Count. For example, if the Monitor Interval is set to 5 seconds and the
Failure Count setting is 5, a failover condition will be identified after 25 seconds of
missed source activity.
Note:
In a cluster environment, make sure to include a cushion to account for the
time it takes for the EVS to failover between nodes. Setting values too low
will cause the Application Manager to assume the source cluster has failed
and will indicate that a failover condition has been met.
a. In the Monitor Interval field, select how often the monitor should check the
source machine availability (Default = 5 seconds, or 60 seconds if
Application Monitoring is selected).
b. In the Failure Count field, select how many monitor replies can be missed
before assuming the source machine has failed (Default = 5 missed replies,
or 3 replies if Application Monitoring is selected).
5. If you are monitoring multiple IP addresses, select one of the Failover Trigger
options.
● All Monitored IP Addresses Fail—Failover begins when all monitored IP
addresses fail.
● One Monitored IP Address Fails—Failover begins when any of the
monitored IP addresses fail.
6. If you selected Application Monitoring as the Method to Monitor for Failover,
enter information in the Application Monitoring Settings area.
a. In the Username field, enter the fully-qualified user name that will be used to
run WMI scripts. The fully-qualified user name must be in the format
domain\username or username@domain.
