value in the device lists. If HP Web Jetadmin cannot obtain a value from the device, it displays <Unknown> in the device lists.

The predefined thresholds are based on the stability of the value for each column. For example, the Severity column is considered out-of-date after 15 seconds because the status of devices changes frequently. The System Contact column is considered out-of-date after 24 hours because the contact does not change frequently. The Model column is never considered out-of-date because the device model never changes.

NOTE: If you use HP Web Jetadmin to update the System Contact value for a device, the 24-hour polling threshold is not valid. HP Web Jetadmin immediately updates the System Contact column in the device lists. If you use another mechanism, such as HP Embedded Web Server, to change the System Contact value, HP Web Jetadmin does not display the updated value in the device lists for 24 hours. However, you can refresh the information in the device lists at any time to reflect the current values for the devices. For instructions, see Refresh device selection in Top Menu Bar Features on page 24.

Follow these steps:

1.On the top menu bar, access Tools > Options > Device Management > Device Polling > Background

2.Configure the desired settings:

●Polling interval: Specify the number of seconds during which HP Web Jetadmin sends device requests to the network. The default is 2.

●Time between polling intervals: Specify the number of seconds that HP Web Jetadmin remains idle between polling intervals. The default is 10.

●Number of devices per poll: Specify the number of devices that HP Web Jetadmin can query concurrently. The default is 2.

HP Web Jetadmin sends device requests for the specified number of devices to the network in a poll burst and waits for the responses. When HP Web Jetadmin receives the response packets, it sends another burst of device requests. HP Web Jetadmin continues to send device requests until the specified polling interval expires, and then waits until the specified number of devices per poll is satisfied before sending new device requests.

3.Click the Apply button.

To reset all of the values to the defaults, click the Reset to Default Values button.
