Example automatic event handling tasks

HP SIM ships with three example automatic event handling tasks that are disabled by default.
When the Automatic Event Handling - Manage Tasks page appears, you can select one of the
example tasks and click View Definition.

example - all desktop information events

This task is triggered when an informational event is received from the discovered desktop
systems, and this task clears the event. The same task can be edited to change the action of
the system criteria .

example - all linux MIB updates

This task is triggered when a MIB update events request is received from all managed Linux
target systems that are discovered and identified in HP SIM. The same task can be edited and
saved as new task.

example - all server failed sign-in events

This task is triggered when a failed sign-in attempt is made. Sign-in failure might be caused
by an invalid user account, sign-in attempt from an excluded IP address, or failed sign-in
authentication.

AEH - ForwardAsTrap in IPv6

The IPv6 address cannot fit into the agentAddr field of the SNMP Trap PDU. The agentAddr is
always 0.0.0.0 for traps from IPv6 systems. When events (traps, indications, and other events)
from an IPv6 system are forwarded, IP header holds the proxy IP (or CMS IP) with agent IP as
0.0.0.0. Hence, use ForwardAsTrap feature to associate the originating IP (source IP) of the trap
to the receiver end while forwarding the traps to the receiver through AEH - ForwardAsTrap.

NOTE:

No changes are required when SIM CMS 7.3 and later versions are used as the receivers.

The Automatic Event Handling ForwardAsTrap feature consists of the following traps:

Forward IndicationsAsTrap

Forward TrapAsTrap

Forward OtherEventsAsTrap

Forward IndicationsAsTrap

For Forward IndicationsAsTraps, to associate IPv6 trap source address, get the target with IPV6
address from openViewSourceName (OID - 1.3.6.1.4.1.11.2.17.2.2.0).

Forward TrapAsTrap

The two methods to obtain the originating IP of the trap are as follows:

Default method: By Default, an additional VARBIND is introduced in all the traps with the
VARBIND NAME as ipv6AddrAddress (OID - 1.3.6.1.2.1.55.1.8.1.1). The VARBIND VALUE
holds the IPv6 address of the trap originator that is the target with the IPv6 address.

NOTE:

If the Target holds only IPv4 address, then there is no additional VARBIND present

in the forwarded trap and the trap contents are same.

Alternate method: Use this method, if all the traps from an IPv6 target are encapsulated as
OpenView Trap and forwarded. Here, the trap data is available from openViewData
(1.3.6.1.4.1.11.2.17.2.4.0) and IPv6 address is available from openViewSourceName (OID
- 1.3.6.1.4.1.11.2.17.2.2.0). For this, the property ipv6_Fwd_Trap_As_ovTrap must be
set to true in globalsettings.props file (located under <SIM_INSTALL_DIR>\config).
