ADM Components
VMwareprovidesADMononeormoreappliances.Themodeoftheappliancedetermineswhichcomponent
isrunning.ADMcomponentsaredescribedinTable 1‐2.
Active Probe
TheactiveprobeistheADMprocessusedforbothDetailandIPdiscovery.Activeproberespondstothe
policiesdefinedthroughthemanagementcomponent,discoverstheitemsassignedthroughthepolicies,and
returnsthedatatothemanagementcomponent.Thisdataisreconciled,stored,andpresentedintheconsole.
To configure the active probe
1Assign
discoveryitemstoaspecificCollector.
2Definetheprotocolsthataresupportedfordiscovery.
3 Connectthemanagementcomponent(Aggregator)tothediscoverycomponent(Collector).

Component Description
ActiveDiscovery‐
Unix
Collectsdatafromtheconfigurationobjectsinyourdatacenter.Thefollowingdiscoverytypes
apply:
 IPdiscovery:DetectshostsorotherconfigurationitemswithaspecificIPaddresswhen
passivediscoveryfailstodiscoverthem.
 Detaildiscovery:ExtendstheinformationobtainedusingpassiveandIPdiscovery.Ituses
commonnetworkprotocolstoremotelyqueryserversinthemanagednetworkandobtains
supplementaryinformationaboutnetworkhoststhatisaddedtothedatabase.
ActiveDiscovery‐
Windows
AdiscoveryenginethatusesWMIbaseddiscoverypoliciesforperformingactive
discoveryon
Windowsmachines.
PassiveDiscovery Passivelyobservesthenetworktrafficbyperformingadeep‐packetanalysistodiscover
applicationsandcomponentrelationshipsinphysicalandvirtualenvironments.
Passivediscoveryalsoallowsyoutodothefollowing:
 Mapdependencies.
 Counttheactivityofthesedependencies.
 Identifyservices.
Aggregator Receivesdatafromthediscoverycomponentsandreconcilesthedatabeforetransferringittothe
databasecomponent.TheaggregatoralsoprovidestheuserinterfaceforusingADMandisthe
integrationpointforvariousintegrations,forexample,ERDB.
Database AnOracleRDBMSusedtostorediscovereddataandADMconfiguration.
