Notifications

Server Manager for Software-Defined Networks notifications lists the key notifications issued by the Server Manager for Software-Defined Networks entities.

Table 1. Server Manager for Software-Defined Networks notifications

Class	Event	Description
ControlCluster	Down	Indicates that the ControlCluster is down.
	ReducedRedundancy	Indicates at least one component is not functioning but the total number of functioning components is above AtRiskThreshold.
	AllComponentsDown	Indicates that all of the components in the redundancy group are down.
	AtRisk	Indicates that the number of functioning components is below the AtRiskThreshold.
ControllerNode	HighDiskSpaceUsage	Indicates that the disk space usage on the controller is high and it might run out of space soon.
	HighMemoryUsage	Indicates that the Controller is using high System memory
	HighSystemLoad	Indicates that the Controller node system load is very high.
	Down	Indicates that the controller is Down.
EdgeGateway	AtRisk	This entity is below the AtRiskThreshold.
LoadBalancerVirtualServer	Disabled	This entity is disabled and is causing protocol problems.
LogicalRouter	AtRisk	This entity is below the AtRiskThreshold.
NSXManager	Unreachable	Indicates not able to contact or reach the NSXManager.
Tunnel	Disconnected	Indicates tunnel is disconnected.
	Down	Indicates Tunnel is Down.
	TunnelTrafficImpaired	Indicates tunnel traffic is impaired due to physical fault.
	Impaired	Indicates that the Tunnel Physical interface(s) is down.
VirtualLoadBalancerPool	AllComponentsDown	Indicates that all load balancer pools are down.
	AtRisk	Indicates that the number of functioning load balancer pool is below the threshold.
VirtualLoadBalancerService	Disabled	This entity is disabled and is causing protocol problems.
EdgeCluster	AllComponentsDown	Indicates that all of the components in the redundancy group are down.
	AtRisk	Indicates that the number of functioning components is below the AtRiskThreshold.
	ReducedRedundancy	Indicates at least one component is not functioning but the total number of functioning components is above AtRiskThreshold.
	ExternalTrafficImpaired	Indicates that external traffic (north-south) is impaired due to a physical failure carrying external traffic.
	ExternalTrafficDown	Indicates that external traffic (north-south) is DOWN due to a physical failure carrying external traffic.
	TunnelTrafficDown	Indicates that Tunnel traffic (east-west) is DOWN due to a physical failure carrying tunnel traffic.
TrasnportNode	Down	Indicates that the TransportNode is Down as indicated by the Instrumentation.
EdgeNode	Down	Indicates that the EdgeNode is Down as indicated by the Instrumentation.
TransportNodeInterface	MightBeDown	Indicates that the transport node interface might be down.
LogicalRouter (Tier 0)	LogicalRouterDown	Indicates Logical Router is Down when All edges are Down.
LogicalSwitch	ConnectivityImpaired	Indicates logical switch connection is impaired due to Physical failures (Interface/Cable/Switch Down).
