shouldPollAllIfNoCriticalServiceDefined

public boolean shouldPollAllIfNoCriticalServiceDefined()

This method returns the configured value of the 'pollAllIfNoCriticalServiceDefined' flag. A value of true causes the poller's node outage code to poll all the services on an interface if a status change has occurred and there is no critical service defined on the interface. A value of false causes the poller's node outage code to not poll all the services on an interface in this situation.

If disabled, an outage will be generated in this scenario.

Specified by:

isServiceUnresponsiveEnabled in interface PollerConfig

Returns:

a boolean.

pkg - a Package object.

Returns:

a List object.

rebuildPackageIpListMap

public void rebuildPackageIpListMap()

This method is used to rebuild the package agaist iplist mapping when needed. When a node gained service event occurs, poller has to determine which package the ip/service combination is in, but if the interface is a newly added one, the package iplist should be rebuilt so that poller could know which package this ip/service pair is in.

Specified by:

rebuildPackageIpListMap in interface PollerConfig
