112 Monitoring and Alerting
Point to Note
• Dell Management Console uses the same protocols to discover and monitor
a device. For example, if you use a custom connection profile, which does
not include SNMP, the
Resource Manager and Performance Viewer will not
display performance metrics and some health metrics, such as:
–
Device Agent Health – OpenManage Storage Management
– Device Agent Health – Dell Remote Access Controller IB (In Band)
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 es tab, select the Dell OnDemand Health Monitor Task.
The OnDemand task defines which metrics should be polled when the
OnDemand alert rule is triggered. This task is displayed by double-clicking
the task within the alert rule or directly through the left pane,
under Monitoring and Alerting Event Console Jobs and Tasks
Dell OnDemand Health Monitor Task.
