There are several configuration options that can be set to affect how device polling is performed in HP Web Jetadmin.

Configure the Background Polling Options

Whenever you access a device list in HP Web Jetadmin, the devices on the network are polled. You can determine how many devices and how often devices are polled by setting the rate on the Background polling page. You can reduce network traffic by setting a polling rate appropriate for your own environment.

HP Web Jetadmin performs a slow-poll when users access device lists. Slow polling means that

HP Web Jetadmin queries only a certain number of devices every X seconds and only for specified columns. The columns polled are based on the union of all columns in the layouts currently displayed on Device List pages on all currently connected clients. This polling rate can be changed through Tools > Options > Device Management > Device Polling > Device List. List performance can be improved by changing the polling rate; network traffic will increase.

NOTE: Another way to refresh the list more quickly is to highlight any or all devices where fast data is desired. Selected devices in the currently visible portion of the device list are always polled at a faster rate than non-selected devices.

Polling always occurs across all devices at the specified rate regardless of whether or not anyone is accessing a device list. Accessing a device list only affects the columns which are polled for when the polling does occur. Selecting devices within the visible portion of the list causes those devices to be polled for at a higher rate.

Polling is also affected by thresholds that specify how long the value for a specific column is considered valid. These thresholds are predefined in HP Web Jetadmin. You cannot change the predefined thresholds. Before HP Web Jetadmin polls a device for column values, it performs the following steps:

1.If HP Web Jetadmin does not have a value for a column, it polls the device. If HP Web Jetadmin can obtain a value from the device, it displays the value in the device lists.

2.If HP Web Jetadmin cannot obtain a value from the device, it checks the age of the value it has. If the age of the value is within the predefined threshold for the column, HP Web Jetadmin considers the value valid.

3.If the age of the value exceeds the predefined threshold for the column, HP Web Jetadmin polls the device to obtain the current value. If HP Web Jetadmin can obtain a value from the device, it displays the
