Discovery Profile Editor

This editor lets you create or modify profiles. It has the following sub-sections:

General

Network

Actions

Inspection

Results

Edit Discovery Profiles

Here are the steps that appear in Discovery Profile Editor:

General

The General Panel collects all required data for a discovery profile. Open Manage Network Manager validates each field, one at a time. Hints and tooltips appear if you hover your cursor near a field or label.

4. General Parameters -- Set the Name, Description and a checkbox to indicate whether this profile is the discovery default.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 Open Manage Network Manager device driver installed. If your system’s license permits it, such management may be possible, but more limited than for devices with drivers installed.

If your license limits the number of devices you manage, discovering such “generic” devices may count against that limit.

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.

Fields like Location query the database for current information, so even though its field may appear empty, Locations may exist. Click the Search button to the right of this field to populate it. Keeping such fields empty until you use them enhances performance.

The buttons at the bottom of the Profile Editor let you navigate through this series of panels. Previous / Next move back and forth between screens, Save lets you preserve whatever stage you have configured, and close the editor, Inspect moves directly to the Inspection screen (described below), and Execute triggers the discovery profile and opens the Results panel, displaying message traffic between Open Manage Network Manager and the device(s). Click the “X” in the top right corner of these screens to close them without saving.

If you discover devices without retrieving their hostnames, and need that hostname later, you can re-run discovery after checking Resolve DNS Hostnames. This fetches the DNS hostname and resyncs the device.

Network

The Network Panel collects the network (IP range, hosts, and so on) and the authentication information for the discovery profile.

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

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

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

Open Manage Network Manager now discovers all IP addresses in a specified range, regardless of the specified base IP address is (middle, starting IP, or last in the range). IP addresses outside of range will not be discovered. You can use the CIDR specification of the network to discover rather that the subnet ID.

6. Authentication -- You can create new, or add existing authentications. See Authentication for the way to create such authentications outside the discovery process.

If a device or its driver requires two authentications and you only enter one, it may not appear in inventory after discovery. To correct this, enter both authentications in the Discovery Profile or in Quick Discovery. If you discover a device partially with only one authentication--typically the SNMP community--you can re-discover with the correct authentications later, or Edit the resource to add that correct authentication and the management interface for it.

Notice that authentications appear with Edit / Delete icons and Up / Down arrows on their right. The Edit icon opens the authentication editor. Click the arrows to arrange the order in which the application tries credentials (top first). Ordering only applies when two credentials are of the same type.

If you have imported a discovery profile without importing or creating the authentications it uses, editing its authentications is not possible. If you cannot import authentications, or have not created them when you do attempt to edit them, the easiest solution is to delete the un-imported un-created authentication the profile refers to and create a new one.

If two similar authentications include one with a “deeper,” enable login, and a “shallower” one without that additional login, arrange to try the deeper login first. If the device rejects it, discovery still tries the shallower one later.

Actions

7. When you click Next, the Actions panel appears.

You can simply accept the default actions that appear here (like Resync, and Learned MAC discovery) by clicking Next to the Inspection portion of discovery, or you can do the following:

Add Action -- This opens a screen with a selection list of available actions. Click Apply to select an action to add to the list for this profile.

Notice the default for this screen displays the most com­mon actions, but you can also click keyword search in the top right corner to display a search field instead of a pick list with the most common actions. The search results appear in the pick list. When you select an item, if it has parameters, they appear listed below that item. Use the checkbox(es) or pick list to configure these parameters, then click Apply to select this action as part of the profile. See Actions for more about these.

Edit, Delete, Move -- These icons appear to the right of each action. If you Edit a profile with parameters, you can change them. The screen looks like the one that appears when you Add actions. Deleting actions removes them from the list, and the Move arrows help arrange the order in which actions appear listed, and are executed. The list of actions the profile executes goes from top-to-bottom.

Inspection

Using the Inspection Panel is an optional step. If you want to execute the profile after entering the required information on the General and Network panels, you can skip this step, and just click Execute at the bottom of the panel.

8. Inspection -- 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 in the top right corner of this screen to begin the inspection process that validates the device’s credentials.

Notice that the Inspection Status fields at the bottom of the screen indicate the success or failure of Ping, Hostname resolution, and Authentications, and the Status column displays whether a valid authentication exists, whether it has been tested, and whether the test is successful.

When authentications are unsuccessful, click the icons to their right to remove or edit them. You can also click the wrench / screwdriver “fix it” icon in the Discover column to open an editor where you can revise the authentications for that device.

Clicking Create New lets you create new authentications, Choose Existing lets you select from existing authentications, Test Device lets you try out the authentications you have selected, and Close closes this screen. Notice that you can configure new or existing authentications’ port, retry and timeout settings before you click Apply (or Cancel) in the authentication editor that appears after clicking the “Fix it” button.

9. Save -- Click Save to preserve the profile. You can then right-click it to select Execute. 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, and the message traffic between Open Manage Network Manager and the device appears on the Results screen.

This produces a standard Audit Trail / Jobs Screen screen displaying the message traffic. See also Audit Trail / Jobs Screen for more about retrieving archives of such screens.

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

12. Click the X in the top right corner of the discovery profile editor to close it.
