Re: [nv-l] NV 7.1.4 and TEC forwarding / Correlation Gateway

Jane, after I realized that my non-TME
Windows TEC adapter was sending events without the gateway receiver being
enabled, I realized that my analysis of your problem was incorrect.
So I asked someone from development to clarify the data flow
for me and here is the response. It looks like with TEC 3.9/NV 7.1.4
nothing in the flow changed despite the fact that state correlation
is active by default in the NetView TEC adapter.
NetView 7.1.4 TEC adapter provides two
different options in event communication. The first option is to
use the socket (non-TME), and, in this case, the event is delivered directly
to the TEC server just as any other TEC adapters would if they were to
use the non-TME option. The second option is to use the LCF (endpoint)
communication, and, in this case, TEC gateway must be installed on the
TME gateway that the endpoint is connecting to.
In both cases, NetView adapter behaves
the same way TEC adapters would since they all use the same set of EIF
libraries.

Jane, there is a change in the TEC architecture to allow non-TME
events to take advantage of the SCE on the gateway. This is done
through the gateway receiver which receives events through sockets and
passes them on to the TEC gateway SCE. Since you have not upgraded
toTEC 3.9 and have not configured your gateway to enable the
gateway receiver, and James says "Non-TME
or not nvserverd will try to use the SCE on the gateway"
this is probably why your events have stopped flowing up to TEC.

Jane -
You are asking me TEC questions that I cannot answer for certain.
My understanding was that the SCE code was now part of the EIF library
functionality that we as an adapter link with.
But I could be wrong about that.
I see references to State Correlation in the TEC User's Guide. When
they talk about the Java API that's what they are talking about. And
the also use the term State Correlation in Appendix C.
All that NetView is doing with this is stuff is providing the Service Impact
events. That's how they are generated.

Thanks James - interesting. Presumably this is only true if nvserverd
and the sce are on the same box (as is my case)??? Otherwise, I don't
see how nvserverd will ever find the sce??
Do you know of anypointers for documentation in this area?
Thanks again,
Jane
