HP Web Jetadmin - Device Information Polling and Related Features

6
A few more important points about supplies polling:
• Supplies levels for devices configured in supplies alerts subscriptions are checked anytime an
SNMP trap is sent from the device (generally this is frequent when the device is established in one
of the general alerts).
• Supplies levels are also tested whenever a 24-hour poll is generated by general alerts.
• Supplies alerts polling rates are non-adjustable.
SUPPLIES POLLING
Separate polling exists for the
Supplies tab (Figure 7), which is
another tab feature activated
with device list selection.
HP Web Jetadmin formerly had a
feature named Supplies Groups
that used the same polling.
Supplies Groups is no longer a
feature in HP Web Jetadmin
software.
DEVICE LIST REFRESH
Another way HP Web Jetadmin gathers details from devices on the network is with its two refresh
features. Detailed descriptions follow:
Refresh Selection
From the device list, right-click and select Refresh Selection or press the F5 key to get real-time status
information for one or multiple devices. With Refresh Selection, the HP Web Jetadmin client queries
devices directly for all of the data it is tracking, even if the data within the database is not expired.
After performing the refresh, normal polling and threshold monitoring continues.
NOTE Although Refresh Selection offers a snapshot of the device status at the time you perform the
feature, some device data—such as page counts—can change quickly, and may not be fully
accurate even moments after the refresh. Depending on the number of devices selected, there
may be a short delay in the data update in your device list.
Refresh Selection (Full)
From the device list, right-click and select Refresh Selection (Full) to obtain complete device and status
information. With Refresh Selection (Full), HP Web Jetadmin clears device data for the selected device
and then re-retrieves the data elements important to device identification. This is useful when, for
example, you believe a device has become disassociated from the IP address recorded for it in the
HP Web Jetadmin database. If the recorded IP address for a device is correct, HP Web Jetadmin
simply updates the device status information, retaining all acquired data. If, however, the IP address
in the database is associated with a different device, HP Web Jetadmin performs the equivalent of a
device discovery and registers the new device into the database. Information about the previous
device remains as well, but Communication Error displays in the device list until HP Web Jetadmin
discovers it under a new IP address or it is deleted.
NOTE For performance reasons, Refresh Selection (Full) is currently restricted to a single device. To
refresh your device database, run a full discovery on your network or on a specific list of IP
addresses using Specified Address Discovery.
