HP Systems Insight Manager 5.2 Update 2 Technical Reference Guide

system and will be configured as the WBEM user in the System Protocol settings. This
configuration step is not necessary if HP SIM is configured with a user with administration
rights. This user is not created by HP SIM. The user should already exist as either a domain
user or one local to the managed system.
The user will be added to the "DCOM Users” group on the managed system and will be
given read-only access to WMI information, plus read-write permissions to the HPQ name
space. This user does not need to be an administrator of the managed system and need not
have logon rights. A special purpose domain account is recommended, and should be created
by the domain administrator.
To enter the credentials for HP SIM to use to access the managed systems:
1. In the User name field, enter a user name.
2. In the Password field, enter the password for the user's name previously entered.
3. In the Password (Verify) field, re-enter the password exactly as it was entered in the
Password field.
4. In the Domain field, enter the Windows domain if the target belongs to a domain.
If configuring a non-administrative user is successful, then these credentials are saved as
the System Protocol settings for WBEM access in HP SIM.
• Configure SNMP. This section enables you to configure SNMP settings.
For this section, the following must be considered:
a. Select Set read community string to specify a community string. By default, the first HP SIM
first community string, that is not public, appears in the field. If no community string exists in
HP SIM, you must enter one.
If only HP-UX systems with default SNMP installation are being configured at this time, you
do not need to set this option. HP-UX enables read by default (get-community-name is set to
public by default on HP-UX systems).
If this option is selected, the Read Only community string is added to the target systems. If
the target system is SuSE Linux or Microsoft Windows 2003, the managed systems do not
always enable SNMP communication between themselves and a remote host. This setting is
modified to enable the instance of the HP SIM system to communicate using SNMP with these
target systems.
You can enter a community string up to 255 characters.
Repairing the SNMP settings adds a Read Write community string to the target system only
if one does not currently exist. This community string is unique for each system, is composed
of over 30 characters to include letters and numbers, and is only visible to the user with
administrator privileges for that system. This Read Write community string is required by the
Web Agent to perform certain threshold setting capabilities. This community string is only
used locally on the target system and is not used by HP SIM over the network. Linux and
HP-UX systems do not require a Read Write community string; hence the Read Write
community is added on Windows systems only.
b. Select Set traps to refer to this instance of HP Systems Insight Manager in the target
systems SNMP Trap Destination List. This setting enables the target systems to send SNMP
traps to this instance of HP SIM.
c. Select Send a sample SNMP trap to this instance of the HP SIM to test that events
appear in HP SIM event lists to verify that SNMP events appear in the HP SIM events list.
To successfully send a test trap, you must configure target systems to send a trap to this
instance.
Note: A test trap can be sent only from a Windows managed system with HP Insight
Management Agent installed. If you attempt to run this task on a Linux or HP-UX managed
system, a message displays indicating the operation is not supported.
Note: The trap will appear as a Generic Trap from the system. This event will appear as an
Informational Event in the Event List of HP SIM.
