SNMP TRAP GENERATOR
In addition to email, alerts can also be sent in the form of Simple Network Management Protocol
(SNMP) traps through the HP SNMP Trap Generator. This alert-forwarding module provides
device-event conveyance through a fully customizable SNMP trap.
An SNMP Trap is typically defined as an industry-standard notification event issued from a device to
the network management station when a significant event (but not necessarily an outage, a fault, or a
security violation) occurs. The trap produces one-way SNMP communication, which can significantly
reduce the need for random status polling of the device and conserve network bandwidth.
A printer-produced SNMP trap is a simple event notification mechanism, and does not always provide
the information needed to determine the most appropriate or efficient course of action. When
HP Web Jetadmin receives a trap from a printer, it launches an SNMP information request process
that is designed to gather additional device information and serve as the content for a more
comprehensive HP Web Jetadmin generated alert. With the HP Web Jetadmin SNMP Trap
Generator, this alert can be forwarded as an SNMPv1 or SNMPv2 trap.
This solution provides integration with Enterprise System Management (ESM) applications such as
HP Openview Operations, HP Openview Network Node Manager, HP System Insight Manager,
CA Unicenter, IBM Tivoli, Cisco
Information Center, or any SNMP
management station capable of
receiving SNMP traps for purposes of
notification and processing.
Helpdesk ticketing systems such as
Remedy and Peregrine may also
benefit from directly receiving printer
alert content in the form of SNMP traps
to generate helpdesk tickets. The
content of the traps that HP Web
Jetadmin sends can be customized to
include only the desired components to
be fed to the appropriate destination.
When imaging and printing devices
send traps, the content describing the
event is typically a five digit code or an
SNMP OID, and the frequency cannot
be controlled. A device sends traps
every time an event occurs. The
advantage of using HP Web Jetadmin
to act as the proxy for these traps is
that events can be filtered to forward
only the desired events at the desired
frequency, and with much more
detailed content than a regular printer
trap.
Traps can be selected as an output
mechanism when subscribing to alerts
