13. USING OPENVIEW NETWORK NODE MANAGER

This section briefly describes some of the features available through OpenView Network Node Manager. We suggest the you become familiar with the HP OpenView Network Node Manager User’s Guide. This guide contains detailed instructions for performing the task listed. The Network Manager application leverages the OpenView Network Node Manager to the fullest extent to achieve maximum similarity between our application and the customer’s other OpenView Network Node Manager applications. Refer to the OpenView Network Node Manager documentation for a complete listing of features.

13.1 LOADING/UNLOADING MIBS

OpenView provides the mechanism to load/unload MIBs via the Options->Load/Unload MIBs main menu selection. By default, the EDACS MIBs are automatically loaded into OpenView.

13.2 VIEWING/GRAPHING PERFORMANCE PARAMETERS

NOTE

MIBs must be loaded to perform these operations.

Several menu selections are provided to graph the EDACS MIB items thought to be of most common interest via the EDACS -> Performance menu bar. However, numerous additional MIB variables are available. See the OpenView NNM User’s Guide sections titled Viewing MIB Values and Setting MIB Values for procedures on using the MIB Browser to read and write MIB values. The MIB Browser provides the capability to graph individual MIB objects.

13.3 ADDING CUSTOM MENU ITEMS

Custom menus are realized using OpenView Network Node Manager’s MIB Application Builder. The MIB Application Builder enables the easy development (without programming) of MIB applications for Internet-standard and enterprise- specific (i.e., specific to a given vendor) MIB objects, and integration of the applications into the HP OpenView Network Node Manager Windows menu bar. The custom menu item created may involve submenu items; therefore, all the user’s custom-built additions may exist under one main menu bar item.

For custom selection, the MIBs Application Builder provides a list of the available performance values for the selected object(s) available for display via a menu item. Each performance value in the list contains the actual SNMP MIB variable name, its object ID, and a short description. The user may select one or more values from this list to monitor. Items for a custom selection must be from the same MIB, and all instances of the object are selected.

This feature is useful for MIB variables of interest on a periodic basis. Custom menu items may be built to view the MIB values. OpenView Network Node Manager has a MIB Application Builder to make this task relatively easy. See the OpenView NNM User’s Guide section titled Building MIB Applications.

NOTE

The MIB Application Builder allows data to be displayed in form, table, or graph format, but does not allow the modification of MIB data. The MIB Browser is used to modify MIB data.

13.4 COLLECTING AND GRAPHING PERFORMANCE DATA

Data may be collected at regular intervals and saved to the /usr/OV/database/snmpCollect directory. The data are readable by xnmgraph. Note that performance data may be saved without graphing. If a graph is later invoked via the MIB browser, all of the previously collected data will be read in to xnmgraph and may be scrolled. See the OpenView NNM User’s Guide section titled Collecting MIB Data.
