Discovery Profiles

Discovery profiles configure equipment discovery for Open Manage Network Manager.

The summary view displays the Name, Description, Default (the green check indicates the default profile), whether the profile is Scheduled and Next Execution Date for scheduled discovery.

The Expanded portlet adds a Reference Tree snap panel that displays a tree of associations between selected profiles and authentication and tasks that they execute. See Discovery Profiles for more about this portlet.

The date format follows the operating system’s conventions for the location and language selected. Restarting the system changes system menus to the new language. If you want to revert back to the original language in Linux, you may also need to update the cache file under /var/cache/gdm.

Discover Your Network

1. Right click the Discovery Profiles list and select New.

If you have a multitenant environment, you can create

2. The Discovery Profile Editor appears, with a step-by-step set of screens to configure resource discovery. You can navigate through it by clicking the screen tab names at the top, or by clicking the Next button at the bottom of the page.

Discovery Profile Editor

Use this editor to configure discovery once you have started Discover Your Network. Baseline discovery is the initial discovery to compare to later discoveries. Follow these steps to discover equipment on your network:

General

3. General Parameters -- Set the Name, Description and whether this profile is the baseline default.

4. Profile Options -- Select the Device Naming Format (how the device appears in lists, once discovered), whether to Manage by IP address or hostname, and check whether to Resolve Hostname(s), ICMP Ping Device(s), Manage ICMP-only Device(s), or Manage Unclassified Device(s). This last checkbox determines whether Open Manage Network Manager attempts to manage devices that have no device driver installed. Management may be possible, but more limited than for devices with drivers installed, provided this capability is one you have licensed.

Some packages disable ICMP ping by default.

The Filters (by Location, Vendor, or Device Type) let you narrow the list of devices discovered by the selected item(s). As the screen says, this filtering will not have any impact on the processing that occurs during the Inspection step.

Make sure you Save profiles you alter, or these selections have no impact when you execute discovery.

Network

5. After you click Next, the Network screen appears.

Network Type and Addresses -- Select the type of entry in the pick list (IP Address(es), CIDR Address, Hostname, SNMP Broadcast, Subnet).

You can specify an IP Address range by separating the beginning and end with a dash. For example: 192.168.1.1 - 192.168.1.240.

The tooltips in the data entry field describe what valid entries look like.

6. Authentication -- You can Create new, or Choose existing authentications. (See Discovery Profiles for details.) Notice that authentications appear with Edit / Delete icons and Up / Down arrows on their right. The Up / Down arrows order authentications, so Open Manage Network Manager tries the top authentication first, then the next, and so on. If you have an authentication like
admin/abc and one that is identical with an enable-level login / password (admin/abc/enable/enable), make sure the enable authentication appears first in the list, otherwise, you will discover the device, but not access its enable functionality.

If you do not get to the correct level of authentications--for example the “enable” user--then Open Manage Network Manager’s full functionality is not available.

The Edit icon opens the authentication editor. Click the arrows to arrange the order in which credentials are tried (top first). Ordering only applies when two credentials are of the same type.

Actions

7. You can configure Actions to run as part of discovery. By default, the actions screen includes the Resync action. Use Add Action to select others to enter here. You can also edit parameters (if available), delete and re-order the actions listed here by clicking the icons to the right of them. Open Manage Network Manager executes them in top-to-bottom order.

Inspection

8. Inspect Network using your current settings -- This screen lets you preview the discovery profile’s actions and access to devices. If you clicked Next rather than Inspect at the bottom of the previous screen, click Start Inspection to begin the inspection process for selected authentications that validates the device’s credentials.

Notice that the Inspection Status fields below listed authentications indicates the success or failure of ping (if not disabled), Hostname resolution, and the listed Authentications.

If the device does not match all required authentications, you can click the Fix it icon (a wrench with a red or yellow dot) to edit them for the selected device. You can also click Test Device, Create New, or Choose Existing authentications while in the editor clicking the Fix it icon displays the authentication selection panel. The yellow dot on the Fix it icon means an optional authentication is missing. A red dot means a required one is missing.

When authentications are unsuccessful, you can remove or edit them in this editor too. Click the icons to the right of listed authentications to do this.

When they test successfully, the authentications appear in a nested tree under the Discover checkbox (checked when they test successfully).

9. Save -- Click Save to preserve the profile. You can then right-click it to select Execute and begin discovery. If you select Execute from the profile editor, Open Manage Network Manager does not save the profile to execute later.

Results

10. Execute -- Clicking Execute begins discovery, confirm you do not mind waiting, and the message traffic between Open Manage Network Manager and the device appears on the Results screen.

This is a standard Audit screen. See Audit Trail / Jobs Screen for more about it.

11. A message (Discovery Profile Execute is complete) appears in the Messages at the bottom left of the status bar.

You can also schedule discovery profiles to run periodically, updating your Open Manage Network Manager database with any network changes. For more, see Schedules.

12. The devices in your network now appear in the Managed Resources portlet, and elsewhere (in Topology, for example).

See Discovery Profiles for more about these capabilities.

Open Manage Network Manager automatically adds discovered devices to the default ICMP monitor.
