Anleitung Zusammenfassung
PROACTIVE MANAGEMENT
While all previously discussed troubleshooting techniques involve reactively responding to a user call
at the helpdesk, HP Web Jetadmin also includes various proactive techniques whereby issues can be
solved before ever being reported by users.
Status
Status can be viewed for individual printers or groups of devices to determine the current state of
each device. Many of the problems causing a warning or error state can be remotely solved before
they are detected by end users. The Severity and Status columns in Layouts can be enabled on any
device list in order for helpdesk staff to find problematic devices.
Alerts
HP Web Jetadmin has the ability to send email messages, or alerts, whenever events occur on
devices. For example, error or warning conditions on devices, such as paper out or toner low, can
trigger HP Web Jetadmin to send email messages containing detailed information on the condition.
The advantage of alerts is that administrators can receive real-time warnings via email for events that
occur on networked devices. Receiving early notification of printer events allows administrators and
helpdesk personnel to proactively troubleshoot and correct problems before they impact end user
productivity. Individuals responsible for ordering consumables, such as toner cartridges, might enable
toner low alerts so they can proactively order toner before it runs out.
Once a device is enabled to send alerts in HP Web Jetadmin, there are two different mechanisms by
which HP Web Jetadmin can be informed that a condition exists on the device:
• Traps: HP Web Jetadmin can listen for device traps that warn of a condition.
• Polling: HP Web Jetadmin can periodically poll a device for status if the device does not support
traps or the traps table is full. For more information, see the document “Using Proactive Alerts with
HP Web Jetadmin,” which can be found at the Self Help and Documentation tab at
www.hp.com/go/wja.
If the status condition of the device matches any of the configured alerts for the device, a detailed
email message is delivered to designated recipients. If a device only supports polling, SNMP status
queries are sent to the device at user-defined intervals and the status is checked against configured
alerts in the same way.
ENTERPRISE SYSTEMS MANAGEMENT INTEGRATION
HP Web Jetadmin provides a bridge for enterprise systems management applications such as
HP OpenView or IBM Tivoli. These applications and others can be configured to launch HP Web
Jetadmin software for specific printers and other imaging devices found within the enterprise
application. Following is how an administrator might use this functionality when managing devices
within HP OpenView.
IT administrators can use HP OpenView’s Network Node Manager to monitor the status of network
hosts such as routers, switches, servers, and printers. This is done with a map of the network or
network segment displayed in Network Node Manager. However, to arrive at appropriate and
specific printing or digital imaging detail, the administrator requires the help of a tool focused on the
variety of features needed to manage these devices. HP Web Jetadmin is that tool.
Once the HP Web Jetadmin linkage, or “bridge,” has been created within HP OpenView software,
the administrator simply configures any printing/imaging devices to launch an HP Web Jetadmin
device view when they are selected. HP Web Jetadmin facilitates this with a simple URL format:
http://WJAServer:8000/device/xxx.xxxx.xxx.xxx—where xxx.xxx.xxx.xxx is the IP address of the
