[edit] Commercial Network Management tools[edit] InfovistaInfovista is a market-leader in Network Performance and Availability Management. Here are some highlights about their solutions.[edit] Infovista architectureThere are two VistaFoundation architectures:
Both architectures consist of:
In both architectures he VistaMart Gateway component collects data polled by InfoVista servers, aggregates and converts it to VistaMart format and then inserts it into the VistaMart Oracle Repository. The Infovista Server collects statistics through SNMP polling, ICMP response-time measurement or log-file import. It is a software application running on Windows or Solaris servers and uses a local Objectstore database to store collected metrics into time-slots. The VistaMart is a data warehousing software application, running on a Windows or Solaris server and providing a central repository (based on a table-partitioned Oracle Database) and provides advanced reporting and analysis capabilities. The VistaPortals are software applications that provide a GUI interface for visualizing in real-time and historical reporting on the collected measurements from the Infovista Servers and the VistaMart. The VistaCockpit is a software application (offering a GUI console) that provides a central management console to administer and monitor the health of InfoVista components, both servers and services. [edit] Classic ArchitectureIn the ‘Classic’ architecture, a VistaProvisioner component uploads topology and configuration data onto designated InfoVista servers. Topology files are usually split to match server collecting capacity. A VistaGateway component is being used to synchronize objects in the VistaMart with those in the Infovista Servers.[edit] Centralized architectureIn the 'Centralized' architecture, VistaMart provisions topology data and configuration directly in the InfoVista Servers and sinchronizes its objects with those on the InfoVista Servers. In the Centralized Architecture there is no need for the VistaProvisioner component.[edit] VistaInsight componentsA VistaInsight component provides the VistaPortal with advanced reporting on a specific area of Infrastructure. Each VistaInsight product addresses specific categories of measurements that focus on specific management needs for the IT infrastructure. Examples are VistaInsight for Servers, for Networks, for IP Telephony or for IP-VPN. Each VistaInsight adds to the "common" Vista model an area-specific part of the InfoVista [Object] Model, that organizes the IT objects being measured into functional categories and establishes the relationships between them.[edit] VistaInsight for Networks (VIN)The VistaInsight for Networks provides functionality for capacity planning, performance monitoring, service-level verification, inventory and surveillance in network environments, by defining measures for:
[edit] VistaInsight for IP telephonyThe VistaInsight for IP Telephony allows management and monitoring of resources and measurements specific to IP telephony environments, especially those related to the QoS aspect of the service. The VistaInsight for IP Telephony is an agentless solution and provides SNMP-based measurements on IP telephony components like Cisco voice gateways, routers or the Cisco Call Manager. It gathers and analyzes Cisco’s IPSLA measurements and Cisco CallManager CDRs to monitor both call and voice quality and to identify present conditions and potential performance issues. The optional VoIP Extension Module, similar in principle and offered functionality to Cisco's IPSLA feature, adds some capabilities to VistaInsight for IP telephony:
The VoIP Extension Module is based on Psytechnics QoS measurement technology, using a Master/Responder configurations, measuring VoIP QoS between the Infovista Servers hosting the VoIP Extension Module. The licensed "Master" component injects synthetic RTP voice streams (every 1, 5, or 15 minutes) into the network with actual voice payload. The Responder receiving the synthetic voice stream calculates the jitter, delay and packet loss, and in turn, injects its own synthetic voice stream into the network. These are the IP Telephony KPIs and Metrics provided by the VistaInsight for IP Telephony:
[edit] VistaInsight for IP-VPNVistaInsight for IP-VPN is geared toward capacity and performance management for MPLS-based VPNs. It relies on measurements obtained through Cisco IPSLA and Cisco proprietary Proxy Ping, for jitter, latency and packet loss. The Infovista Server will automatically provision and activate (through SNMP) the IPSLA probes into the the Cisco routers specified by the report. The following metrics are collected and analyzed:
[edit] VistaViewsVistaViews define all the necessary provisioning within InfoVista Servers to collect, analyze, store and report on a particular set of performance metrics. Each VistaView comes with a set of pre-built reports targeted to specific performance metrics of specific categories of devices, equipment or technologies.Available VistaViews:
[edit] VistaView forInfoVista IP Telephony - Cisco CallManagerIt uses source data coming from devices supporting the CISCO-CCM-MIB and NT-PERF-MON-MIB. It provides reporting on:
[edit] VistaView for MPLS Traffic EngineeringThe VistaView for MPLS Traffic Engineering provides MPLS tunnel (LSP) service-performance statistics coming from the MPLS-LSR-MIB and the MPLS-LSR-TE-MIB. The metrics, which include load and error statistics (alowing network administrators to take traffic-rerouting decisions) and tunnel exceptions statistics (in the event of link failure or rerouting problems), allow reporting on:
[edit] VistaView for VoIP - Cisco IPSLAThe VistaView for VoIP - Cisco IPSLA provides QoS statistics by retrieving from CISCO-RTTMON-MIB the measurements obtained by running Cisco IPSLA tests. It provides reporting for:
[edit] VistaView for Cisco VoIP GatewaysThe VistaView for Cisco VoIP Gateways is extracting information from a variety of voice-specific MIBs and provides reporting on:
[edit] VistaBridgeA toolset allowing extending Infovista capabilities by importing data from external sources into :
Based on predefined configuration files VistaBridge handles instance creation or reconciliation and can start reports and associated indicators. Examples of use cases:
[edit] SMARTS InChargeThe original documentation for the SMARTS Incharge product suite can be found here. The Cisco's Network Connectivity Center is an OEM product based on SMARTS InCharge 6.2 and its documentation is a good reference for SMARTS InCharge.The software components of the SMARTS InCharge solution are:
[edit] ICIM HierarchiesThe InCharge CIM (ICIM) model represents the managed network system as two parallel hierarchies: physical and logical. A physical network element is a hardware device or component to which one could attach an inventory tag (e.g. a server, router or switch). A logical network element provides some service or connection between other elements, e.g. a protocol, routing table, virtual interface, VLAN or class of service. The element classes are connected through association relationships (e.g. "ComposedOf" or "PartOf"). All physical element classes (e.g. Card, Chassis, Rack) are subclassing the ICIM_PhysicalElement class (actually ICIM_PhysicalPackage), describing elements with physical characteristics. In terms of object model, ICIM_PhysicalPackage, represents physical elements that can contain or host other physical elements. All logical element classes are subclassing the ICIM_LogicalElement class, which describes abstract system components (e.g. ProtocolEndpoints, LogicalLinks, logical devices). During the discovery process, when specific instances for the "leaf" ICIM classes are generated, the AM/PM tries to match the SysObjectID values it reads (through SNMP) from discovered Network Elements against an internal database of "certified" devices. Each instance of a particular "leaf" class has metrics associated that the AM/PM can collect through SNMP, from standard or proprietary MIBs. Not all logical elements are recognized on all device types, even on "certified" ones, as many of the metrics might reside in proprietary MIBs, although the certified Cisco network devices are generally well supported in terms of MIBs.Important ICIM logical element classes, largely modeled after DMTF`s CIM framework, are:
During the discovery process logical association relationships among created element-class instances are established, as for instance:
[edit] Service Assurance ManagerThe InCharge Service Assurance Manager (SAM), also reffered to as Global Manager, consolidates topology information and event information it receives from its underlying "domain" managers:
Each domain manager (AM/PM or other) is responsible for discovering the network topology of the domain it manages. The SAM consolidates the event information, does root-cause analysis and applies business rules (e.g. setting severities, applying escalation rules, correlating events, opening incident tickets within ticketing systems). Detailed and summary event and alarm information are displayed in the SAM Consoles (Notification log, Topology Browser, Map Console,Summary View). From these consoles, operations personnel can invoke diagnostic or corrective tools, acknowledge events or generate reports. The connectivity among the Incharge components (SAM, domain managers, adapters) goes through the Incharge Broker, which allows for encrypted communication and automatic failover schemes. [edit] SAM Open Integration (OI) and the Trap AdapterThe InCharge Service Assurance Manager permits development and interfacing of "adapters", through the Open Integration platform APIs. The adapters inject events they detect into the SAM, where the same business rules, correlation and consolidation apply as for events coming from the other domain managers. The Trap Adapter is such an adapter which receives SNMP traps (on UDP/162) and remaps the TRAP contents into an event format to be fed to SAM. The mapping of TRAP contents (generic/specific TRAP IDs and var-bindings) into SAM event attributes is doner through a mapping configuration whic may invoke advanced mapping scripts written in ASL language. The Trap adapter is a convenient means of propagating into SAM events generated by other monitoring systems, e.g. Integrated Research Prognosis IP Telephony Manager. It is advisable that the network elements identified as "source" (after trap attributes processing through the mapping configuration) exist in the SAM topology, either discovered or manually entered. Several instances of trap adapter can run on the same SAM, each one listening on a particular port and mapping traps with its own configuration, allowing per-domain processing of external events. The XML adapter offers a convenient means of importing and exporting SAM network topology information (using the ICIM XML external format).[edit] IP Availability/Performance ManagersThe Availability Manager (AM) instances, one per domain, discover and monitor the network elements using ICMP ping and SNMP polling as well as by receiving and processing SNMP traps sent by network elements. The abnormal or "back-to-normal" situations detected by the AM are analyzed for root-cause then fed to the SAM as notifications, being displayed in the Notification Log console. The types of notifications are "up", "down", "unstable" (i.e. flapping), or "not responding" for systems, network adapters, cards, connections, etc. A number of standard and proprietary MIB objects are supported by the AM. Once the network elements are discovered and the network topology built, the InCharge Performance Manager (PM) would monitors specific metrics and the status of these elements by periodically querying them through SNMP polling, ICMP ping as well as by receiving and processing SNMP traps. The decision on which network elements to monitor is based on "management policies", which can be configured. Those network elements being declared in "unmanaged" status are nor monitored (e.g. by default switch access ports are not managed). Singular abnormal conditions (e.g. high utilization on a port) result in "fault" notifications whereas related faults are aggregated and reported as "exception" notifications. Several instances of AM/PM managers, also reffered to as Domain Managers, can independently run on the same server by binding to different virtual interfaces and managing each network elements in a particular IP ddressing domain. This collocation feature allows Managed Service Providers (MSP) to reduce the infrastructure costs and manage overlapped the private IP addressing domains of multiple clients, using Policy Based Routing (PBR) based on source IP address.[edit] SMARTS extensibilityWhat distinguishes SMARTS InCharge from other Network Management Systems is its extensibility features:
The MODEL language allows the base ICIM model to be extended with user-defined classes to represent new types on Network Elements to manage. The "base" ICIM model, which is "compiled" into a set of SMARTS InCharge shared libraries is actually defined in MODEL. As new classes are defined by the user in MODEL scripts, they have to be run through the MODEL compiler which first translates them in C++ clases then to binary-compiled shared libraries to be loaded by SMARTS at startup. The MODEL-defined extensions to the ICIM model are "static" in the sense that one need to restart the SMARTS InCharge applications to activate them. Technology-specific "managers" exist for SMARTS InCharge to fulfill advanced monitoring needs for:
The SMARTS InCharge Remote API interface, a RPC mechanism based on a client-server protocol that allows remote applications to invoke SMARTS InCharge services and manipulate objects in a SMARTS InCharge ICIM instantiation. To do this, the Client application is using the classes and methods implemented in the libraries provided with the Remote API SDK libraries, which would issue requests and synchronously waiting for responses, while doing the marshalling/demarshalling of request/response parameters into/from messages. The following basic functionalities are provided through the Remote API:
These extension mechanisms permit development of third-party applications that complement the SMARTS InCharge capabilities for fulfilling special requirements. One such example is the Advanced Performance Grapher (APG) which adds historical perfprmance reporting and analysis capabilities to SMARTS InCharge. [edit] Other Performance Monitoring ToolsOther Availability, Fault and Performance management tools are being used by IS/IT organizations and Network Providers - Among these are Concord (now Computer Associates) eHealth suite, HP OpenView Network Node Manager (NNM), IBM Tivoli Suite and others. Despite the vast choise, the information below refers only to eHealth, NetScout nGenius suite and the Application Performance Monitoring tools from Compuware and Packeteer.[edit] Concord eHealthConcord Communications, who bought in 2005 Aprisma Management Technologies (for the "Spectrum" fault and service management), was bought the same year by Computer Associates. The CA/Concord eHealth suite is valued by many organizations for its powerful performance reporting capabilities,for just about every aspect of network monitoring, including VOIP. The eHealth suite is primarily a network performance monitoring tool, collecting its information through SNMP (directly from devices or from RMON probes) as well as from proprietary SystemEdge and Application Response agents deployed on monitored servers. The eHealth suite also provides a VOIP deployment planning and assessment module which is using the agents and the Cisco IPSLA metrics to assess network impairments. In typical deployments eHealth does the performance monitoring and HP-OV NNM the fault monitoring and topology map.[edit] IBM/Micromuse NetcoolThe IBM Tivoli/Netcool suite is primarily a Manager of Managers (MOM) whose core is the Netcool/OMNIbus system, which collects, archives, consolidates and presents in real-time enterprise-wide event/alarm information from various sources. The strong point of Netcool is the abondance of adapters and proves for different other Network Management Systems and Network Devices. Using these adapters and probes Netcool can import Network Topology, correlate event information and assess the business impacts of network troubles.
[edit] Netscout nGenius Performance MonitoringNetScout Systems nGenius suite combines network monitoring, application service-level management and capacity planning in one package. The NetScout suite evolved since the acquisition in 2000 of NextPoint Networks. It provides Real Time Monitoring, Application Service Level Management and Capacity Planning. The information is gathered by SNMP from NetScout probes, NetFlow collectors, from routers and switches and other sources. The collected metrics are analyzed in realtime for pinpointing issues and stored in a database for reporting and trend analysis. Starting with version 4.5, NetScout introduced a unified Common Data Model(CDM) format (provided in the proprietary CDM Flow MIB residing on the nGenius probes) for the metrics collected by the nGenius probes.Along with CDM, the nGenius PM server supports a Common Data Export (CDE) format for easier integration with 3'rd party applications.
[edit] Compuware Application Vantage and Packeteer AppVantageThe Compuware Application Vantage is a tool for monitoring application & transaction performance.[edit] Network Change and Configuration Management (NCCM)These are tools able to retrieve and audit configurations from network elements, to keep an inventory of Network Components with their attributes. Some tools can also automatically push configuration and firmware updates to devices and alert in case of unauthorized changes. ACcording to Gartner up to 80% of all network infrastructure failures are direct results of mis-administration and poor configuration The NCCM market leader seems still to be Alterpoint with its DeviceAuthority/NetworkAuthority suite, with a base configuration starting at US$10000. An Open Source version of the framework (ZipTie) allows for customization and adapter development. The Opsware Network Automation System (NAS) is based on the acquisition of Rendition TrueControl and benefits from a Cisco partnership. It competes with AlterPoint, Intelliden and Voyence, with a pricing starting at $20,000 for 50 nodes. AdventNet offers also the Device Expert NCCM product. A very low cost alternative to these expensive toolsets is Kiwi CatTools For server configuration auditing, the Tripwire toolset is widely used in the industry.
