Node |
Represents either a workstation, server, or a network device, such as a router, hub, or bridge. |
Property |
A text string that describes the type of node or one of the node's MIB objects. Polls and alarms use properties to target specific nodes. Assigning a node to a property group that contains multiple properties allows the node to be targeted by multiple behavior models. |
Poll |
Periodically solicits SNMP values from the agents running on targeted nodes and fires a trigger when specified conditions are met. Polls can fire multiple triggers, which are detected by one or more alarms. |
Trap mask |
Detects a predefined type of SNMP trap. Trap masks can define generic and specific traps as well as traps coming from certain types of devices or whose contents match user-specified criteria. A trap mask fires a trigger when the specified type of trap is detected. |
Alarm |
Receives triggers, correlates one or more detected network events, and tracks each event instance. Alarms can include automated actions, which fall into four categories: notifying, logging, triggering other alarms, and correcting network conditions. Actions can also be performed conditionally using NerveCenter's Action Router. |
