NodeStatus

Path: /model/node_status/nodestatus_models.mod

This multi-alarm behavior model monitors the status of nodes and, optionally, their SNMP agents.

The SnmpStatus alarm monitors the status of nodes and their SNMP agents. Uses built-in triggers to determine if a device is up, down, or unreachable. Monitors nodes associated with a property group that contains the property system.

The IcmpStatus alarm monitors the status of nodes based on their response to ICMP echo requests (pings). Determines if a device is up, down, or unreachable. Nodes must be associated with a property group that contains the property icmpStatus, but they are not required to run SNMP agents.

Property

The following property must be in the property group for the nodes you want to monitor:

system (SnmpStatus alarm) and icmpStatus (IcmpStatus alarm)

Trigger Generators

Below is a list of the objects that generate triggers:

Events Sent to OpenView
