HP Web Jetadmin - Using Proactive Alerts with HP Web Jetadmin

are desired, use alerts under the Supplies subscription type.
Many of the supplies alerts offer a set of three types: Low, Very Low, and Replace. One of three
techniques is used to process these three alerts, depending upon the device, in order of preference:
1. If the device supports a dedicated status OID for low/very low/replace, such as
consumable-current-state, it will be used.
2. If no status OID, Web Jetadmin will query remaining level % using objects such as
prtMarkerSupplies. Hardcoded threshold vales will be used to send alerts for low (20%),
Replace (3%), and Very Low (1%).
3. If neither technique above can be used, Web Jetadmin will inspect the prtAlerts table for
events.
Cartridge Error is a generic, non-specific supply error alert that covers errors on a multitude of
supplies.
Some supplies will be named differently on various devices although the functionality of the supply is
similar. For example, the Cleaning Kit alert can represent either a cleaning kit on devices such as the
HP Color LaserJet 9500/9500mfp or a toner collection unit (TCU) on devices such as the HP Color
LaserJet CM3530 and CP3525. Web Jetadmin queries remaining levels to obtain the percent
remaining for cleaning kit, but it will use supplies status objects for TCU. In other cases, the
FutureSmart devices that use eventing such as the HP Color LaserJet CM4540 MFP, Web Jetadmin
represents the TCU on the device as an alert named Waste Collector. Web services eventing is used
to process these alerts.
Supplies Subscription Type
The Supplies subscription type allows the user
to define when a supply becomes low or out by
setting a user-defined threshold. This differs
from the supplies alerts under the General
subscription type in that the user defines the
level, rather than the device or HP Web
Jetadmin defining the level.
Users have the flexibility to subscribe only to
the desired supply event(s). Also, one supply
can be set to one threshold value while another
supply can be set to a different threshold value.
Alerts for one supply can be sent to one
individual while alerts for another supply can
be sent to a different individual.
You can set the alert threshold based upon the
type of supply and then set it to send an email to the person who is responsible for that type of
supply. There may be different people in the organization responsible for replenishing supplies, and
the ability to send alerts at different thresholds for those different people based upon the type of
supply is important.
In addition to email, the supplies threshold alerts can be forwarded to other locations, such as SNMP
Trap Generator or Alert History.
Supplies categories include (see Figure 2, above):
 Toner/Ink—Estimated supply levels for ink or toner
 Maintenance Kit—Estimated remaining life for maintenance kit supplies
