snmp trap is not received.

[mikewate]

There is a standalone network of Windows2003 and RHEL4.
I installed SIM5.1 on Windows2003 and PSP7.7 was installed in RHEL4.
Each machine writes the computer name in the hosts file, and solves the name.
Each machine connects mutual trust.

The entry was added to /etc/snmp/snmpd.conf of RHEL4.
rwcommunity [community name] [SIM IPaddress]
rwcommunity [communityname] 127.0.0.1　
trapsink [SIM IPaddress]


Disc Threshold was set for the test.
However, SIMServer doesn't receive the trap.

Besides, please teach if there is a necessary setting.

Not totally familiar with RH, but in VMWare the trapsink line includes the community name after the SIM IP Address.

If you can connect to the HP Agent, under Settings -> SNMP WebAgent -> SNMP Configuration there's a Trap send button. That should generate a trap that can be used to test.

The detail in the VMWare snmp.conf is;

rwcommunity [rwname] 127.0.0.1
rocommunity [roname] 127.0.0.1
rwcommunity [rwname] [SIM Server name]
rocommunity [roname] [SIM Server name]
trapcommunity [roname]
trapsink [SIM server anme] [roname]

Before accusing HP SIM of not receiving the trap, you need to check the originating host to make sure it actually sent a trap. Is there an event in /var/log/messages that corresponds to the threshold?

Secondly, beware that Windows Server 2003 installs SNMP by default to only respond to localhost. If that's the case, SNMP would throw away a trap sent to it.

Thank you for everybody.
I'm sorry that the reply is delayed.

"Test trap" was transmitted from "SNMP configure" of system management homepage.
ï¼ "Net-snmp util" was installed. ï¼
"Test trap" was received by SIM.

The disk threshold can be observed though the machine for the watch was tried as
Windows2003.

I execute this command with RHEL4.
/etc/init.d/hpasm reconfigure
The trap of the disk threshold was sent to SIM immediately after the re-setting.
However, even if the disk threshold exceeds it afterwards, the trap is never sent.

The disk threshold cannot be observed at any time though it seems to be able to receive
the trap.

The trap is only sent at the point the threshold is crossed. The disk space needs to go below the threshold and then back over for a resend.

Restarting the agents while a threshold has been exceeded will also generate a trap.

Thank you!

solved it.
Reset threshold was mistaken and set it.
