Monitoring and Alerting 153
OnDemand Monitoring
OnDemand monitoring allows the Notification Server to instantly collect a
set of metrics when an SNMP alert is received.
This feature is used to poll the device health when an SNMP trap, which may
affect health, is received from a device. This enables accurate and efficient
update of the device health when the hardware health changes as opposed to
waiting for the next poll interval to update the health.
For this feature to work, enter the IP address of the Dell Management
Console system in the managed system’s SNMP services configuration for
SNMP Trap destination.
For other types of devices, see the device documentation for configuration
procedures to forward traps to the Dell Management Console system.
The OnDemand feature is enabled by default.
NOTE: This feature requires that the device is configured for SNMP management
as the feature is dependent on SNMP traps from the device.
You can find the OnDemand task and alert rules in the Monitoring and
Alerting portal page. The OnDemand alert rule defines the conditions
required to trigger the OnDemand task, and controls whether or not this
feature is enabled. This rule is displayed on the left pane, under Monitoring
and Alerting Event Console Alert Rule Settings. On the right hand
pane, in the Tas k Rul e s tab, select the Dell OnDemand Health Monitor
