hp toptools for openview nnm user guide
5 Using hp toptools for openview nnm
HP Toptools for OpenView NNM enhances NNM functions and integrates the functionality of HP Toptools directly
into the native HP OpenView NNM console. The first noticeable enhancement can be seen upon displaying the
NNM map. Each HP device is now displayed with a custom HP icon. A table of HP icons is shown in Table 1.
Each HP device now has an enhanced menu of action items which are accessible from the NNM Tools menu, or
within the context menu of a selected node object. Note that in most cases, you must select one or more nodes in
order to enable HP Toptools menus. Right-clicking the mouse over an HP node will not enable the HP Toptools
menus, you must select the node or nodes. Nodes may be selected through selection on the map, or as the result of a
search using the Find By utility. For more information on selecting nodes and creating selection lists, consult your
NNM documentation.
5.1 toptools Authentication and openview nnm
If you install the toptools server on the same system as HP OpenView NNM, security settings for access to toptools
will not be an issue. However, if the toptools server is installed on a separate system, authentication for requests
from the system running HP OpenView NNM may be requested.
By default, only users in one of the toptools groups (“toptools”, “toptools operator”, “toptools admin”) on the
toptools server are permitted access to toptools pages. You must add NNM users to the one of the toptools groups. If
no additional users are added, then the first attempt to launch a browser on the OpenView NNM system will result in
an authentication prompt. Once you have added users to one or more of the toptools groups on the toptools server
subsequent toptools page requests will be automatically authenticated without prompting using NT authentication of
the cached credentials.
NT authentication will automatically send user information transparently, and no prompting of a password will
occur. Care must be exercised in this approach in order to avoid permitting unauthorized access to toptools. Users
logging into the user account used to operate OpenView NNM can now gain access to the toptools actions (such as
locking or rebooting all the HP devices in your organization).
5.2 hp Device Discovery
Each time the hpttBrdgDisc service is restarted (for example, by doing a ovstop/ovstart) the HP discovery program
attempts to classify all devices in the ovwdb database by doing extended SNMP and DMI/WMI discovery on those
devices. For each HP device discovered, the icon on the NNM map is changed, and additional functionality is
enabled via the toptools menu in NNM. The discovery process is not instantaneous; extended DMI/WMI and
SNMP requests can take some time. Discovery can take over an hour. A file, hpttBrdgDiscData.log, notes each
discovered HP device and can be used to monitor the status of the reclassification. For more information on how
bridge discovery works, refer to the "Troubleshooting" section of this document
.
5.3 Launching toptools from nnm
You can access the toptools home page from the NNM menu. To access, go to the NNM Tools menu and scroll
down to the “HP Toptools” menu item. From the cascading menu, select “Toptools Home. This will display the
toptools home page on the configured toptools system. You can then access the toptools functions such as the
Network Performance Advisor directly.
5.4 Finding hp Devices
The NNM Find tools help you quickly locate devices and create selection lists based on attributes such as selection
name or device type. HP Toptools for OpenView NNM discovers HP devices and links them to new attributes for
NNM. On the NNM map select Edit menu, Find-> Find By Attribute (see Figure 5-16 and Table 2).
