Ok, but how are the wpostemeg scripts being kicked off?  Rulesets? Automatic
actions from traps?  If rulesets, are they listed in ESE.automation?   If you've
got a problem open to Support as David said, then they will be asking you all
the same questions if they haven't already.
In all the years I have done this, I have never had a problem with nvserverd
that didn't start somewhere else.

I am a co-worker of David Tremblay.  Dave hurt his back (unrelated to
Netview :) and is out today so I'll reply to the posts.

You are correct that we mean the standard Events Window.

The two Netview environments are identical with respect to the database,
generally everything under /usr/OV including scripts that are called from
Event Configuration.  All network devices forward SNMP traps to both
servers.  We do no direct forwarding to TEC; rather via postemsg commands in
the scripts.  The scripts are all run in the background, so as not to
interfere with trapd or ovactiond.  An environmental variable is set which
differs on the two servers -- that is how scripted events get forwarded
differently to our production TEC, and debugging TEC.

trapd.log shows relatively low incoming activity (just checked - 10 events
in the last 5 minutes).  In spite of the Events Window problem, as I
mentioned trapd.log is normal, traps are being handled correctly and the
scripts are forwarding to TEC just fine.  nvserverd is still pegged at 50%
of the total CPU load (2 CPUs).

     I've given this some more thought, and I'll bet we have a
terminological problem
     here.  You said "Events HIstory" but I'll bet you don't mean that.
I'm betting
     that what you really mean is the standard (current) events window,
the one you
     get when you start the GUI or type in "nvevents" from the command
line.  Events
     History is a different application all together.

     Anyway, I seriously doubt if your two boxes are really identical,
because then
     they would both be forwarding to TEC.  Are they really?  Even if
they are, I'll
     also bet that the test box doesn't get nearly the same volume of
traps that the
     production one does, correct?

     In any case if nvserverd is using 50% of the cpu, then he is one
busy boy, and
     that can only mean that  (a) traps are coming in at a fairly rapid
rate, and
     that he has multiple event windows he's trying to send to, and I'll
wager that
     he is also having difficulty sending to TEC, as well.   Are you sure
that TEC
     events are not being cached in /etc/Tivoli/TEC/cache?  Are you sure
that the
     last event you see in trapd.log that should be forwarded to TEC  is
not in the
     cache and that you can see it with wtdumprl over on the TEC?
Because if you
     have TEC transmission problems that will most definitely slow
nvserverd down to
     crawl and could produce the symptoms you are seeing.

     Events History has nothing to do with trapd.log or current events
being sent to
     TEC.  trapd maintains the trapd.log, and nvserverd sends the events
to TEC,
     after they have been processed by trapd and nvcorrd.

     Events History is maintained by a separate process which registers
for traps
     from trapd, just like all the current event daemons do.  That
process is
     ovesmd, the ems_sieve_agent.  He formats them and passes them to the
     ems_log_agent, ovelmd, who stores them in formatted form in
     /usr/OV/log/ovevent.log.  That's where they are read from.

     And remember that Events History, unlike current Events, does not
update
     automatically.  Once you have done your initial Query, the contents
of the
     window are fixed, until you refresh it  by pulling down "Query"
again and
     clicking "Display Event".
     Then they are updated with the current contents of the ovevent.log.

     So if this isn't working, I would first check whether your
ovevent.log is
     growing and if not, whether the ems_log_agent and the
ems_sieve_agent are still
     running.  ovstatus should tell you that.

     Hello all,

     I am currently working with support on this issue but I am wondering
if
     anyone else has experienced this problem.

     Has anyone ever had their Event History Window stop taking in events
but
     their trapd.log continue to run ok and even continue forwarding
events to
     TEC??  All the Netview Daemons look ok for the exception of one that
pegs
     the CPU at 50% which is nvserverd.   After a reboot everything is ok
for a
     day or so and then we are back into the same problem with the Event
Viewer
     not picking up events anymore.

     This is the situation we are currently experiencing but their weird
part is
     that our test/staging server which is supposed to be identical has
not
     exhibited any of the symptoms I have mentioned above.   The
test/staging
     server even uses the exact same database that is copied over
nightly!!!

     We are running NetView 5.1.1 (on purpose) with integration
forwarding events
     to Tivoli/TEC on a Solaris 2.5.1 box with over 2 gig of memory.

     If anyone has any ideas, please reply.

     Thank you.
