HP Web Jetadmin - Columns for Device Lists

There are numerous columns in HP Web Jetadmin. This number continually increases as new devices, functionality, and plug-ins are released. You can use the columns to sort and customize the device lists.

The columns in device lists contain simple data or complex data. HP Web Jetadmin obtains most of the data that appears in these columns by querying the devices, but some of the data is specific to HP Web Jetadmin.

Use the following steps to add or remove columns in device lists:

Access any Device List. Right-click in any column header and select Customize. The Select Columns wizard is started.
To specify the columns displayed on this page, select one of the following options from the Category drop-down list:
- Favorites: Displays the most commonly used columns.
- All: Displays all of the available columns, except obsolete columns. To display only a specific category of columns, expand All, and then select the category.
- Obsolete: Displays columns that are still available in HP Web Jetadmin, but have been replaced by new columns or will not be supported in the future.
Select the column by highlighting it and clicking the arrow buttons between the two lists. To select multiple columns, use either Ctrl+Click or Shift+Click. To move all devices from one list to the other, use the double arrow buttons.

Some complex columns support displaying portions of their detailed information as individual columns. These complex columns display the detailed items as children in a tree structure in the column selection control. To see the detailed information that can also be used as columns, expand the complex column. When you move a detailed item to the other list, the name of the item is displayed followed by the name of its parent in parentheses.
Click OK. The changes should be reflected on the Device Lists.

Complex Data in Device List Columns

Some columns in device lists cannot display the complex data stored on the device or in the HP Web Jetadmin database. These column cells contain summary data instead of the actual data.

When you add a complex column to a device list, an icon is displayed next to the column title. When you hold the cursor over the summary value in a column cell, a tooltip opens with detailed information about the column and subproperties. The tooltip displays for 1 minute or until you move the cursor outside of the tooltip. Every time you move the cursor within the tooltip, the 1-minute timer starts over.

The information in the tooltip can also be complex. The tooltip displays a summary of the complex data with an icon that indicates more data is available. When you hold the cursor over the complex data in the tooltip, another tooltip opens and displays the next level of data.

The following are examples of how the data for a complex column is displayed in device lists:

Device Groups column: If a device does not belong to a device group, the column cell contains None. If a device belongs to only one device group, the column cell contains the name of the device group. If a device belongs to multiple device groups, the column cell contains <Multiple>. When you hold the cursor over <Multiple>, a tooltip opens with a list of the device groups.
SNMP Trap Destination Table column: If a device supports the SNMP trap destination table, the column cell contains a summary value in the format of <xx> of <yy>, where xx is the actual number of entries in the table and yy is the maximum number of entries in the table.

For example, if a device has two entries in the SNMP trap destination table and has a maximum of five entries, the cell column contains 2 of 5. When you hold the cursor over the column cell, a tooltip opens with detailed information about the column subproperties. The following is an example of the information displayed in the tooltip:
```
                  SNMP Trap Destination Table
Number of Entries: 2
Maximum Entries: 5
All Entries:
Slot  IP Address      FQDN  Port    Community
1     192.168.0.254         27892   wja
2     192.168.0.6           27892   wja

                
```

Columns Dependent on HP Web Jetadmin Data

Some column data is internal to HP Web Jetadmin and is not obtained from the device, such as device status or other data specific to the local application.

Examples of these columns dependent on HP Web Jetadmin data are:

User Defined Settings: Custom columns that can be created by users and then populated with data that is only resident on the application. (In previous versions of HP Web Jetadmin, this used to be called custom fields or custom settings.)
Acknowledged: Shows if you have defined the device as Acknowledged. Acknowledging devices can be done by right-clicking any selection of devices in any devices list.
Credentials Required: Shows requests for required credentials that were not met.
Discovery Date/Time: Time and date of the last discovery.
Last Communication: Time and date of the last communication.
Last Discovered: Time and date of the last discovery that found this device.
PC-Connected: If a device is locally connected to a PC.
Status: HP Web Jetadmin status message about the device.
Severity: Severity rating of status for the device.
Groups: Shows the group membership for a device, listing ether a single group or the word “multiple”. If you hover-over it with your mouse a listing of all groups is displayed.

You can enable two different columns that help track discovery and communication and represent internal device date/time tracking: Last Communication and Last Discovered. These time stamps are updated whenever a discovery has occurred in which the device was discovered or re-discovered.

Device List Columns That Display HP Jetdirect Data

Some of the columns in the device lists display data that is retrieved from HP Jetdirect print servers.

The following are examples of device list columns that display HP Jetdirect data:

Jetdirect Model
Jetdirect Port
Jetdirect Revision

The IP Hostname and System Name columns can be displayed in device lists. These columns are useful, but they can be confusing. The following is an explanation of how these columns use HP Jetdirect data:

The IP Hostname column displays the device's hostname that is retrieved from a network Domain Name Service (DNS).

HP Web Jetadmin uses the device's IP address to perform a reverse DNS lookup. If the device's IP address is registered in DNS, DNS returns the device's IP hostname to HP Web Jetadmin. HP Web Jetadmin displays the returned value in the IP Hostname column for that device. If the device's IP address is not registered in DNS, DNS cannot return an IP hostname. HP Web Jetadmin displays <Unknown> in the IP Hostname column for that device.

Tip:
To enable DNS lookups, go to Tools > Options > Shared > Network > DNS. You can disable DNS lookups for security or performance purposes.
The System Name column displays the device's system name object that is bound to the HP Jetdirect print server. You can use HP Web Jetadmin or the HP Embedded Web Server to change the system name on the device. For many devices, the system name is defined by the Host Name field in the network configuration area of the HP Embedded Web Server.

The device's bound system name cannot be resolved directly through DNS. For example, if the device system name is changed to PRTR445 and the device name associated with the device's IP address in DNS is lab412, HP Web Jetadmin displays lab412 in the IP Hostname column.

HP Jetdirect print servers provide several features you can use to register the device's system name in DNS. These features include the following:
- Dynamic Host Configuration Protocol (DHCP): In many cases, if a device's IP address parameters are configured in DHCP, the device's system name can be registered in DNS. The ability to register the device's system name in DNS depends on the DHCP system on the network, HP Jetdirect print server model and firmware version, and system name populated on the HP Jetdirect print server. For more information about DHCP and DNS name registration, see the technical documentation for the HP Jetdirect print server.
- Windows Internet Name Service (WINS): Many HP Jetdirect print servers are capable of exposing the system name through the WINS network service. WINS and DNS linkages can make the system name available in DNS and in the IP Hostname column in HP Web Jetadmin. For more information about IP hostname and DNS registration, see the technical documentation for the HP Jetdirect print server.

Statuses on Device Lists in HP Web Jetadmin

You can select columns to view on Device Lists from a static list of columns.

The various statuses might be displayed in those columns include:

Unavailable: The device does not support the column.
Undefined: For the HP Jetdirect version when the device is incapable of reporting that attribute.
Missing: Usually a temporary status until the device communicates its data to HP Web Jetadmin.

Manipulating Columns in Device Lists

Learn more about this topic.

You can manipulate columns on the device lists in HP Web Jetadmin:

Selecting Devices: Selecting a device means performing some action that causes the device to become selected which sets up the device or devices for some further action. Click to select one device or Shift+Click to select multiple devices.
Resize columns: To set the width of a column, click and drag the column marker in the list header to the desired width. Or, to resize the column to the broadest width required to display the data, double-click on the column header.
Sort columns:
- To sort the entire device list by a specific column, click in the header for that column. Click again to reverse the sort.
- To perform a secondary sort on a list, use Shift+Click on a different column after the initial sort.
- To perform additional sorts, hold down Shift while clicking on different column headers.
Display or hide columns: To display or hide columns, right-click on the column header. The columns that are currently displayed have a check mark next to them; the ones that are not displayed (or hidden) have nothing next to them. Click on the columns to display or hide.
Right-click menus: Various kinds of right-click menus are displayed based on whether something is selected and what list is displayed. For example, if a device is selected on a device list, right-clicking within the device list causes different menu options to be displayed than right-clicking when no devices are selected.
Re-order columns: Move columns around in device lists by dragging-and-dropping them in the header to where you want them.
