682.0. "TeMIP - HP Openview connection" by KNEIPE::CSCHMIDT () Mon Feb 10 1997 15:57

Hello,

in a pilot installation of TeMIP we have to connect to HP Openview as 
Networkmanagement system. The HP openview serves as management platform 
for many network elements and collects the corresponding traps/alarms.

TeMIP will now be used as an umbrella management system and we need to
get the collected traps from HP Openview into TeMIP Alarm Handling. 

Does anybody know if (and when how) I can forward the traps from HP
openview to TeMIP? I am not familiar with HP openview. But I think there
should be a possibility to forward the traps/alarms to TeMIP.

Or does anyone see another solution? We do not want to use TeMIP as
NMS system itself, but as umbrella management system for different kinds
of NMS (not only HP openview, but we start with HP openview).

Another question: can Visual TeMIP help here?

Thank you for help

682.1develop a proxy on OpenviewTAEC::DEPAGNEMon Feb 10 1997 17:5329
Hi,

I am not an expert in HP Openview, but this can help you :

As far as I know, there is on HP Openview a trap manager collecting
traps from different systems. If you want to forward these traps
towards another manager, you must develop a proxy application 
running on the HP Openview system ; in this application, you must :

 1- create an Event Forwarding Discriminator  
 2- collect the traps using this EFD
 3- Forward these traps ...

Step 1 and 2 are done using HP openview API routines, unfortunately 
you will have to use some XMP routines (such as mp_receive ...) 

Note that you can benefit from the HP Openview "distribution" : your
appli runs on a given Openview system, and can collect traps coming 
from other Openview systems, using the EFD.

For step 3, you have to decide which protocol you are going to use 
to forward the traps: cmip, snmp or whatever. For example, if you
use snmp, your HP openview system will be seen as a proxy agent.
According to the protocol you use, there are some possibilities to
receive them on TeMIP using the accurate access module 
(could be snmp_am, collection_am , specific AM ... ?)

682.2snmp traps directly in TeMIP ?KNEIPE::CSCHMIDTTue Feb 11 1997 11:0117
Hello,

is it also possible to tell the SNMP-agents of the NE's to send the
SNMP-traps directly to the ip-address where TeMIP resides?

I mean it would be very convenient to receive directly the snmp-traps
from the NE's via the SNMP_AM of TeMIP.

Concerning your proposal with the EFD:
When HP Openview forwards the received traps to TeMIP, what will be
shown in the TeMIP Alarm Handling as "sender" of the trap?
Will the contence of the original trap be changed?
In TeMIP Alarm Handling we need to identify the source of the trap, that
means to Network Element and not the HP Openview system as "sender" of
the traps.

682.3it is up to youTAEC::DEPAGNETue Feb 11 1997 13:1815
Christiane,

If you can directly sends traps from snmp agents, I think it is
better : but it means you are able to configure these agents.
In your case I thought you wanted to perform some local
management using HP Openview, and forward only some selected
traps to the umbrella system (TeMIP here). If you want to
bypass the intermediate system, sure you can use the snmp_am.

Concerning the EFD, if you develop a proxy application, this
appli gets the original traps using the EFD, but forwards anything you
want to the umbrella manager (as I wrote in .1, the format of the 
forwarded data and the protocol you use, it is YOUR choice)
