The most likely cause is that the traps
from the devices and the traps you are generating are not using the exact
same enterprise, generic, and specific trap ids. Devices don't always send
what you expect from looking at the MIB. Sometimes there is an extra 0
or something on the enterprise. To see what exactly is coming in from the
devices. you need to turn on tracing.
nvcdebug -d rules
Then watch in /usr/OV/log/nvcorrd.alog
and blog to see how it is deciding whether to forward or not.

| RE: [NV-L] trapd forwarding to tec |
|
Thanks James!
But I have the rule specified
in my ruleset TEC_ITS.rs to forward the events to TEC. Moreover
when I try to send a test trap with the same enterprise ID using SNMPTRAP
utility, I can see these events are being forwarded to TEC. Here my issue
is with the traps forwarded by the actual device those are not reaching
TEC; though it manages to reach in trapd.log.
Also I checked and all the
event property under discussion is in “Status Events”.
Still need helpJ
Regards
Senny

Subject: RE: [NV-L] trapd forwarding to tec
On Unix, only those traps selected
by the TEC ruleset specified in /usr/OV/conf/tecint.conf will be forwarded
to TEC. The flow is like this:
trapd gets all traps --> sends all traps to nvcorrd --> nvcorrd selects
traps to forward to TEC using the ruleset specified in tecint.conf -->
selected traps are sent to nvserverd for formatting and sending to TEC
--> nvserverd formats the trap, logs it, and gives it to the TEC EEIF
library for sending.
If your trap is trapd.log but not in nvserverd.log, then it never made
it through the ruleset specified for TEC. The standard ruleset is TEC_ITS.rs.
It only selects a basic subset of NetView events to send to TEC. If you
want to add others, then you have to edit the ruleset.
Note that some users select forwardall.rs as their TEC ruleset but this
can be prone to problems, especially performance ones because it sends
a lot of stuff to TEC. TEC is not designed to handle large volumes of worthless
information. Using forwardall.rs is not officially supported.

RE: [NV-L] trapd forwarding to tec |
|
Hi,
I have this issue too.
I have all the events are being forwarded to TEC from NetView but the recently
added Trap definition is not being forwarded to TEC. I enabled NVServerd
Trace but no luck (No event seen inside the log).
My problem here is the same. I mean I can see the event sent by the device
in trapd.log, but not been seen in nververd.log and TEC.
If I manually send a test trap with the help of snmptrap command, I am
receiving this event on TEC. What other thing could raise this kind of
issue?
Need help!
Thank
Senny

Thanks. The traps appear in trapd.log so I'm assuming it's a rulesest issue.
I'll give nvcdebug a try and may raise this with support. We have fix pack
5 in plan for second half of the year so maybe I can push to get this brought
forward.
Thanks for you help.

Tracking down missing events is
not something I recommend customers do on their own without help from Support,
but I will explain how to do it.
The first thing I would do is start running the nvserverd trace. nvserverd
is the daemon who send events to TEC. You can trace his activities by editing
/usr/OV/conf/tecint.conf and uncommenting the line
#NvserverdTraceTecEvents=YES
Then you can get nvserverd to reload the file with the command
nvtecia -reload
This will cause nvserverd to write every event he processes to a new file,
/usr/OV/log/nvserverd.log. When you think you have missed an event in TEC,
look in this file and see whether it was logged. If you see it logged then
nvserverd gave it to the TEC library code for forwarding but the adapter
suppressed it for some reason. In that case, you'll have to open a problem
to the TEC folks to get them to help you trace the adapter code. After
nvserverd write the event to his log, he is blind to what happens to it
after that. You will need to monitor the growth of the nvserverd.log. There
is no size limit and no code to restart it after it grows to a certain
size. If you delete or rename it while nvserverd is running, he will simply
start writing to a new copy.
If you are missing the event in TEC, and it's in the trapd.log but you
don't see it in the nvserverd.log, then I would suspect a ruleset problem.
To diagnose that you can start running the nvcorrd trace. nvcorrd is the
daemon who gets events from trapd and correlates them before passing them
on to nvserverd for display or forward. To do that you would issue
nvcdebug -d all
This will cause nvcorrd to start writing what he is doing to the nvcorrd.alog.
After he has written a 1000 lines, he switches to the nvcorrd.blog. After
a another 1000 lines there, he switches back to the alog again and so it
goes, alternating between the logs so that they don't get too big. But
on a busy system they fill up fast, so as soon as you notice a problem
you might want to shut him down or copy the logs so they don't get overwritten.
Alternatively you could edit the /usr OV/conf/ovsuf file and edit it
0:nvcorrd:/usr/OV/bin/nvcorrd:OVs_YES_START:nvsecd,trapd::OVs_WELL_BEHAVED::/usr/OV/conf/FFDC/scripts/nvcorrd_FFDC:5:
to add a log file parameter to nvserverd's definition, like this
0:nvserverd:/usr/OV/bin/nvserverd:OVs_YES_START:nvsecd,nvcorrd:-l/usr/OV/log/mynvcorrd.log:OVs_WELL_BEHAVED:30:/usr/OV/conf/FFDC/scripts/nvserverd_FFDC:5:
If you do this nvcorrd will only write to that log rather than switch.
But you will have to manage it, just as you do with nvserverd.log.
That's about all I can tell you except that when nvcorrd gets an event
you will see a "received an event" eyecatcher in the log. Immediately
thereafter you will see him try to match it to one of the rulesets he is
running. If the match is successful he'll write out all the parameters
of that event. Then you will see him process any actions for that event
and finally forward it on. He'll do this for each ruleset in turn and when
he's down with each of them you will see another eyecatcher in the log
which reads "finished with the event".
Now having said all that, I would urge you to get help from Support with
this. And I would also urge you to get current first. FixPack5 has been
available since December 2006 and there have been fixes made to TEC forwarding.
You are so far behind on maintenance that it is difficult to guess where
the problem lies. Do your missing Compaq traps have null data in them?
Long strings of hex zeros? We fixed a problem like that some time ago.
And that's why you should get current before trying to figure this out.
Your problem might already be solved.

[NV-L] trapd forwarding to tec |
|
Hi
In my forwarding rule set I have the compaq enterprise selected and then
a number of specific traps selected to forward to tec. Some of these get
forwarded and other don't. As far as I can see the traps are all set up
in the same way with the event category set to Status Event.
If I generate one using serversetup, that gets straight through to tec
so I'm assuming this doesn't go through the ruleset. Is this correct and
can anyone offer any suggestions as to how I can track down the problem?
I'm running on AIX, with Netview 7.14 FP4
Thanks
Jane
