Managed element
Definition
Bridge
Isa UnitaryComputerSystemthat 'bridges' packets at the link layer between physically separate segments.
DirectoryServer
Represents aspecialized server whose job is to respond to requests for specific resources, services, users, groups, and so on.
DNSService
Represents a Domain Name Services server for hostname to IP address and IP address to hostname resolution.
Firewall
Is a node that provides firewall functionality.
FirewallService
Represents a firewall application; a software component which acts as agatekeeper of networks deciding which packets are allowed to pass fromone network to another.
FTPService
Represents a File Transfer Protocol Service for exchanging files between computers on anetwork.
Host
Is a UnitaryComputerSystemthat represents aworkstation or server.
Hub
Is a ComputerSystemthat connects multiple physical segments. A hub may be'unintelligent' in that it does not discriminate the segments connecting to it, for example, it relays traffic through all ports. Contrast this witha Switch or Bridge which maintains information about device location and only forwards traffic through specific ports based onthe destination address.
IMAPService
Represents a Post Office Protocol server which allows users to remotely manage e-mail arriving in their inbox using the IMAP protocol.
InChargeServic e
Represents an InCharge application.
IP
Is the IP-layer characteristics of a network-attached interface.
LDAPService
Represents a LDAP server for directory access.
LoadBalancer
Is aspecial systemwhich uses a heuristic algorithmto distribute work units to its components.
MailServer
Represents a programthat distributes files or information in response torequests sent through e-mail. MailServer contains additional information.
MessageQueu eService
Represents an application that provides queue-based messaging services.
MgmtAgent
Represents amanagement agent running on ahost that monitors operating systemand application parameters.
MgmtService
Models an application that provides management functionality. The rationale for this sub-class was to clearly distinguish management applications fromtheservice-delivery applications they manage. MgmtService contains additional information.
MgmtServiceC heck
Represents acheck to verify that the Management interface of the SoftwareElement is accessible or functional. MgmtServiceCheck contains additional information.
MSFC
Represents aMultilayer Switch Feature Card. Such a module is often installed as a Card ina Switch to performrouting between VLANs.
NameServer
Represents aname resolution server. Several domains use these types of servicestoresolve names into addresses or other kinds of information.
NNTPService
Represents a Network News Transfer Protocol Service for managing notes posted on newsgroups.
Node
Represents ageneric computer system.
POPService
Represents a Post Office Protocol server which allows users to remotely retrieve e-mail fromtheir inbox using the POPprotocol.
Probe
Is a ComputerSystemthat monitors networks or systems. For example, an RMONprobe.
ProtocolEndpoi nt
Represents a communication point of the network element from which data may be sent or received. For example, a router interface or a switch. ProtocolEndpoint contains additional information.
RedundancyGr oup
Represents aspecial collection of managed systemelements. The aggregated components together provide redundancy. All elements aggregated inaredundancy group should beinstances of thesameobject class. RedundancyGroup contains additional information.
Router
Is a UnitaryComputerSystemthat routes packets between computer networks. Routers operate at Layer 3 of the OSI model.
RSFC
Represents a Route Switch Feature Card. The RSFCruns Cisco IOS router software and directly interfaces to the catalyst switch backplane to provide inter VLAN routing.
RSM
Represents a Router Switch Module. Sucha module is often installed as a Card in a Switch to performrouting between VLANs.
SecureShellSer vice
Represents the software that enables SSH clients to connect remotelly to amachine through a secure(encrypted and authenticated) communications channel.
SMTPService
Represents a Simple Mail Transfer Protocol Service for sending and receiving electronic mail.
SNMPAgent
Represents an SNMP agent running ina system. An SNMP agent implements one or more MIBs and provides access to the MIB data to SNMP management applications using the SNMPprotocol.
Software Process
Represents asingle instance of arunningprogramdefined by a workspace of memory resources and environmental settings that are allocated to it. Auser of the operating systemwill typically see a software process as an application or a task. SoftwareProcess contains additional information.
SoftwareComp onent
Represents a software element that provides support for, and is executing in the context of, a SoftwareService.
SoftwareComponents do not provide the full service, rather they formbuilding blocks for the implementation of a SoftwareService. SoftwareComponent contains additional information.
SoftwareConne ction
Aggregates multiple sessions and transactions connecting two applications into a single logical entity. SoftwareConnection contains additional information.
SoftwareEleme ntCheck
Represents acheck done toverify status or performance of SoftwareElement(s). SoftwareElementCheck contains additional information.
SoftwareReque st
Models a particular interaction or message exchange between services. SoftwareRequest contains additional information.
SoftwareServic e
Represents a software task. Instrumentation about the availability and response timeof an service—froma URL page monitor, for example—should beassociated with checks. The ComposedOf relationship models the decomposition of a SoftwareService into more detailed components. The LayeredOver relationship models a service that is directly dependent on another service. Both services must be hostedby thesame system. SoftwareService contains additional information.
SoftwareServic eRedundancyG roup
Represents a collection of SoftwareServices that together implement a service. The multiple instances of the application are typically accessed ina fault tolerant manner thereby providing application redundancy. SoftwareServiceRedundancyGroup contains additional information.
SoftwareSessio n
Models a persistent connection between services. SoftwareSession contains additional information.
Switch
Is a UnitaryComputerSystemthat 'switches' packets, typically at wire speeds, between physically separate segments.
SystemRedund ancyGroup
Represents acollection of systems that provide redundancy.
TCP
Describes the characteristics of a TCP listening EndPoint as is used by network services such as HTTP servers.
TCPConnectivit yCheck
Represents a check ona SoftwareElement that verifies the TCP connectivity to the SoftwareElement. TCPConnectivityCheck contains additional information.
TelnetService
Represents the software that enables Telnet clients to connect remotelly to amachine via atext based interface.
TerminalServer
Is a ComputerSystemthat represents a Terminal Server or similar access device.
TerminalServic e
Represents a software service that enables users to remotely interact with a computer systemas if they were at a local console. TerminalService contains additional information.
Uncertified
Is used to identify asystemthat has not yet been certified by the InCharge discovery sub-system.
UnitaryComput erSystem
Represents computer systems. Computer systems are logical elements that host application services and are composed of file systems, disks, memory, and processors. UnitaryComputerSystem contains additional information.
VirtualSoftware Service
Represents the logical service provided by an application redundancy group. The VirtualApplication is LayeredOver the RedundancyGroup that implements the service. VirtualSoftwareService contains additional information.
VirtualTCP
Represents agroup of TCPs that are load balanced.
WebTier
Is alogical grouping of software services, redundancy groups, and systems whichimplement theWeb-basedaccess totheapplication service.
