3 HP OpenView Network Node Manager, Technical Data HP OpenView Network Management Product Numbers B1009A for Series 300, 400 B1024A for Series 600, 700, 800 B1034A for SunSPARC Welcome to HP OpenView HP OpenView Network Node Manager provides fault, configuration, and performance management for multivendor TCP/IP (Transmission Control Protocol/Internet Protocol) networks on a site or campus. Based on international standards, Network Node Manager manages network devices that are IP-addressable and/or run the Simple Network Management Protocol (SNMP). Network Node Manager 2.0 runs on HP 9000 Series 300, 400, 600, 700, and 800 computers with HP-UX 7.0 or later. Additionally, Network Node Manager runs on SunSPARCstations with SunOS version 4.1 or later. Part of the HP OpenView family of system and network management products, Network Node Manager includes a graphical user interface based on OSF/Motif, as well as on-line help and documentation to allow network administrators to put the product to work within minutes instead of days. With the explosion of TCP/IP-based local and wide area networks, corporate Internets, and client-server computing, network administrators need solutions today to minimize network downtime and maximize their productivity. Network Node Manager maximizes productivity by greatly reducing the amount of time administrators spend on network troubleshooting and administration tasks. [Figure: HP OpenView Network Node Manager, caption: none] Network Node Manager 2.0 offers a number of enhancements over 1.0. To guarantee true multivendor interoperability, HP has included the ability to build applications that use vendor-specific SNMP MIB objects and vendor-specific traps, as well as the ability to add applications to the menu bars. It also includes historical data reporting and user-defined thresholds. All of these new features can be put to use quickly and without any programming. HP OpenView Network Node Manager solves the critical problems customers face today in deploying large networks. Features and Benefits HP Openview Network Node Manager lets network administrators understand the health of their networks at a glance. HP Openview Network Node Manager provides a cost-effective, comprehensive solution for managing multivendor computer environments. Through the centralization, automation, and simplification of tasks, users significantly reduce operating costs and improve service levels. Network Node Manager 2.0 offers three valuable features: Discovery, Single View Management, and an Application Builder. ________________________________________________________________________ Feature ________________________________________________________________________ Based on standards such as TCP/IP, SNMP, and OSF/Motif (see Required Sun Software for information about Sun windowing environments). 4 ________________________________________________________________________ Easy-to-use graphical user interface based on OSF/Motif; online help and documentation. ________________________________________________________________________ Automatically generated and updated network mapping: Network Node Manager automatically generates a TCP/IP network map in minutes. ________________________________________________________________________ Extensible and customizable: a true multivendor network management application. ________________________________________________________________________ Continuous network monitoring: once a network map is generated, Network Node Manager continuously displays the status of overall network connectivity on the map, using color to highlight information. ________________________________________________________________________ Event notification: network administrators can decide when to be notified about changing conditions on the network. ________________________________________________________________________ Network diagnostic tools let users isolate and correct identified problems from a central workstation. ________________________________________________________________________ Integrates existing applications: end-users and developers can easily integrate existing shell scripts and applications into Network Node Manager menu bars. ________________________________________________________________________ Dynamic Data Collection and Thresholds: User-specified SNMP MIB object data reporting and event thresholds. ________________________________________________________________________ Benefit Ensures effective management of a wide range of network devices and systems from other vendors as well as from HP. Network administrators can use Network Node Manager to effectively manage their networks within a few minutes of installation. Saves network administrators hours of entering configuration information once a network is discovered. Network Node Manager tracks on-going changes as they occur. Lets users manage any SNMP device without programming, including standard and vendor-specific Management Information Base (MIB) objects; menu-driven sets provide control. Gives network administrators a single place to look to determine the overall health of the network and a head start toward maximizing network availability. Eliminates unnecessary interaction with the network management system. Allows network administrators to work from a central location rather than pursuing problems around the facility. Protects investment in tools the network administrator is already using and ensures a smooth transition from present network management tools to Network Node Manager. Network administrators can get the current and historical network information they need to understand the dynamic aspects of their network for network planning and troubleshooting. Discovery 5 Network Node Manager automatically discovers, maps, and continuously monitors all network and system resources across a TCP/IP network. As the network changes, the Discovery capability automatically shows the changes and updates the network map. Single View Management New and existing user or third-party applications can be easily integrated in a matter of minutes, protecting the user's investment. Application Builder Users and developers can quickly build applications to manage network devices and resources that use the industry-pervasive, multivendor Simple Network Management Protocol (SNMP). Dynamic Data Collection and Thresholds Users can get the current and historical network information they need to understand the dynamic aspects of their network for network planning and troubleshooting. The chart outlines the general features and benefits of Network Node Manager. Network Node Manager's management tools currently fall into three major categories: fault management, configuration/system management, and performance management. The following sections explain the innovative capabilities of HP OpenView Network Node Manager in more detail. Fault Management Network Status Continual connectivity verification for IP-addressable devices is performed automatically using the TCP/IP utility ping. Results are color-coded on the network map (green for up status, red for down status, and yellow for marginal status). Continuous Network Discovery After a map is generated, Network Node Manager continues to find new nodes as they are added and automatically determines if nodes are deleted from the network. Other topology changes, such as the addition and deletion of network interfaces, are also reflected in the map. User-defined thresholds Users can determine what is critical for their networks and set thresholds, which, if exceeded, will generate an alarm. Network Node Manager does threshold checking by polling nodes specified by the user. Specific parameters on which thresholds can be set: o CPU load on HP-UX and SunSPARC systems o Percentage of disk space used on HP-UX and SunSPARC systems o Number of packets received with errors o Number of packets sent with errors o Number of collisions on the network o Number of frames received with CRC errors Event Notification 6 A variety of sources generate alarms within the network management system. These alarms are presented to the network administrator via the network map, an event browser window, and an event log. Specific alarms may indicate a network failure: o Threshold exceeded for one of the conditions described o Failure to communicate with a host performing routing o An SNMP node started or stopped forwarding packets o An SNMP node has the wrong link address for another node o An SNMP node did not respond to an SNMP request o SNMP nodes do not agree on a link address for a node o Agent network interface is down o Network is critical due to the number of nodes down o A particular network segment is critical Menu Encapsulation Users can easily add their own applications to the Network Node Manager menu bar by simply specifying a title and action for the menu item in a registration file. Users utilize a node selected on the map as the input to a command launched from a menu item. Applications launched from menus can include any executable command or shell script. For simple TTY applications, Network Node Manager automatically creates a terminal window to contain the output. For X-Window applications, the display is automatically output to the screen. Trap Formatting and Actions Many SNMP devices send traps (events) that are specific to that device. With trap formatting and actions, the network administrator can: o Specify the text message that will be logged when a particular vendor-specific trap arrives at the management station o Specify a program to be executed when a particular trap arrives, such as calling the network administrator's beeper o Execute shell scripts or any executable command upon the arrival of a trap Remote Diagnostics Tools that facilitate troubleshooting have been integrated with the network map. Tests may be initiated quickly on nodes selected from the map with the mouse. Remote tests include: o IP test uses ping to check physical connectivity from the manager system to a remote node or between two remote nodes o TCP test performs a TCP connection to determine if a connection can be established to a remote node o SNMP test tests if a remote node has an SNMP agent running Easy information access To expedite problem resolution, users have quick access to essential information by selecting nodes from the map and choosing menu items. This information includes: o Addressing information for remote systems including IP, link level (Ethernet), and subnet mask values o Contents of a remote system ARP cache o Disk space utilization on HP-UX systems 7 o A record of the most recent events received by the manager application from a particular node o Interface information and statistics for remote systems o Contents of a remote system routing table o A list of network services operational on a remote system o Contents of the TCP connection table for a remote system Manage/Unmanage Network administrators have the capability to define the scope of what is managed and to determine which parts of the network must be discovered and monitored at any given time. Managed nodes are polled for status and configuration on a regular basis. Unmanaged nodes are not polled except when specified by the network administrator. Remote Terminal Users have convenient access to remote systems via virtual terminal applications through the network map. Terminal types are hpterm for terminal emulation to HP systems, xterm to most other UNIX(r) systems, and vt3k for use with HP 3000 systems. Map Snapshots The current network map can be saved and used later to help determine what has changed in the network. Find Network Routes Users can view graphical and textual displays of the route a packet takes through the network between any two systems. Command Line Commands Network Node Manager includes a number of commands that can be executed directly from the command line. These commands allow the user to access most of the information on the network via a dumb terminal. These commands include: o Get an SNMP value (snmpget) o Set an SNMP value (snmpset) o Send an SNMP trap (snmptrap) o Query a node with SNMP Get Next Request (snmpnext) o Query a node repeatedly with SNMP Get Next Requests (snmpwalk) o Print out the map database o Find the route between two nodes (findroute) o Take a snapshot of the map database (mapsnap) o Check connectivity between two nodes (netcheck) o Check a node's complete configuration (nmdemandpoll) o Check an HP-UX or Sun node's disk space (rbdf) o List network information of a remote mode (rnetstat) o Remote packet echo from one node to another (rping) Configuration and System Management Dynamic Map Automatic generation and continual updating of the network map and associated database eliminates significant manual recordkeeping by providing a central electronic record of network configuration information. 8 HP Bridge/Hub Layout The network administrator has a clear view of a network's physical configuration to aid in both troubleshooting and inventory. Network Node Manager automatically discovers HP's IP-addressable 10-10 Bridges, remote bridges, EtherTwist hubs, and fiber hubs. When these devices are discovered, Network Node Manager automatically lays them out properly on the map. In the case of bridges, it automatically detects which nodes are on which side of the bridge. In the case of the EtherTwist and fiber hubs, it detects which ports have nodes connected and which have other hubs connected and lays out the map accordingly. Easy Map Editing Users can represent information on the map that cannot be dynamically discovered, such as the addition of non-IP devices and details of the physical topology. This mouse-driven editing includes the ability to: o Move objects o Add objects to the map o Delete objects o Add connections between objects o Delete connections between objects o Change object types MIB Browser Users can easily point-and-click their way down and up any SNMP device MIB tree. Any object's value can be retrieved as a single value; multiple objects can also be retrieved in table form. Numerical objects can also be graphed in real-time. Setable MIB objects can be set through this same dialog box. Set security is provided via community names. Application Builder Users have the ability to put the query of an MIB object or objects into Network Node Manager menus. The query can get a single MIB object value, a table of values, or a real-time graph. Used in combination with the MIB Browser, MIB encapsulation gives both full SNMP interoperability and flexible display of data. Event Notification Alarms generated due to configuration changes are: o Network interface added to a system o Network interface removed from a system o New node discovered on the network o Node removed from the network o SNMP node started or stopped forwarding packets o Node link level address changed o Object identifier changed for a node o System description changed for a node o Node name changed o Subnet mask changed Map Snapshots Snapshots record the current inventory of devices on the network, eliminate manual recordkeeping, and provide a central electronic record of network configuration information. 9 List of Remote Network Services Users can access information about services available on a remote node. Online Node Description With a single mouse button click, information can be retrieved about a node's location, contact name, type of node, and network configuration. In addition, the network administrator can add free-form comments to the node description, such as serial numbers and other relevant information. Integration of SAM Remote system administration for HP-UX systems can be driven from the network map. By using HP System Administration Manager (SAM), you can configure software on systems on the network. Locating Map Objects Users can locate objects by various attributes. This is useful for inventory control and for finding systems in large networks. Attributes that can be searched include: o Host name o IP address o Link (Ethernet) address o Object type (gateway, workstation, PC, mainframe, etc.) o Nodes running SNMP o String search in comments Performance Management Real-time monitoring of statistical information is provided in easy-to-read graphical form. Data on peaks and averages associated with the polling statistics is provided for easy trend identification and problem tracking. Dynamic Data Collection and Thresholds Users can gather historical information for any numerical MIB element on any SNMP device or group of devices. This information is saved to a binary file and can be printed in a number of user-defined ASCII formats or accessed directly. The saved files can be imported into popular spreadsheets or SQL databases. Users also can define thresholds on any numerical MIB element. Both features can access MIB I, II and enterprise-specific objects. Additional Features: o Selections can be made using wildcard designations o Event messages are triggered when thresholds are reached o Users can define threshold reset values o Time synchronization between manager and agent for data collection o Menu driven CPU Load of HP-UX and SunOS Systems Users can monitor the relative CPU load of HP 9000 systems and SunSPARC systems running the HP iOpenView TCP/IP Agent for SunSPARC. Interface Traffic Interface traffic includes the following: o Incoming packets 10 o Incoming packets with errors o Outgoing packets o Outgoing packets with errors Link Traffic Users can monitor and graph the following LAN (Ethernet or IEEE 802.3) card statistics for HP-UX SNMP node receptions and transmissions: o Frames transmitted o Frames received o Frames deferred o Collisions o CRC errors Polling Intervals The user can decide how often to poll remote nodes for statistical information. This is important because it lets the administrator control the amount of network traffic generated to perform network management. For busy networks, the interval between status polls can be increased to hold down network traffic. Managed Devices IP-Addressable Devices Network Node Manager will discover, map, and maintain status on all IP-addressable devices on the network whether or not the devices run SNMP agents. This includes HP 3000s, PCs, and numerous devices from other vendors. SNMP Devices Using its extensible MIB capabilities, Network Node Manager 2.0 can manage virtually any SNMP device whose agent conforms to standards. Manageable devices include HP 9000 Series 300, 400, 600, 700, and 800 systems; HP/Apollo DN Series systems running TCP/IP; other UNIX systems such as IBM RS/6000, DEC Ultrix, and Sun; virtually all TCP/IP routers, HP bridges and EtherTwist hubs; many other vendors' network bridges and multiport repeaters; and numerous other devices. Connectivity Connectivity between Network Node Manager and other vendors' SNMP agents is supported for any agent that conforms to the SNMP specification RFC 1098 and to the first version of the Internet-standard Management Information Base, which is covered in RFC 1066. In addition, Network Node Manager can handle vendor-specific SNMP objects through its extensibility features. As long as an SNMP device MIB object description file is in proper ASN.1 format, Network Node Manager can read it and access the special MIB objects. Using this feature, Network Node Manager can manage virtually any SNMP device.
