Re: [nv-l] polling daemon problems

[jason.ctr.alburger@faa.gov]

I don't see any recent cores for xxmap or gtmd.  I'll keep an eye on it,
though.

Any ideas on the "synchronizing" or the ovspmd core?  Is it possible
they're not related to my polling daemon problems?

Thanks!!

Sounds like you have an xxmap problem, since he would be the one updating
the GUI for nvotChangeVertexStatus( ).  He works in tandem with gtmd.  gtmd
gets the call, updated the database, and xxmap should change the status on
the GUI, just like ipmap does for netmon.
They both have to be running for this stuff to work.  I would be checking
on that before I did anything else.  If xxmap is not starting you can
restart from the GUI Tools menu.  And start looking for core files from one
of these two.  But if you find any, you'll probably have to call Support
and open a problem.  These programming interfaces are not popular and very
few people use them.

RH 7.2, NV 7.1.3 + FixPack 2

Hello all,

I'm polling a handful of MIBs on different boxes with custom built polling
daemons.  I've custom built topology icons under some nodes to represent
these MIBs and use the polling daemons to control the status of the icons.
I have a myriad of problems with my snmp polling daemons - so here goes:

1.) All works as it should for about 15 minutes after ovstop/ovstart.

2.) After about 15 minutes, calls to nvotChangeVertexStatus( ) in the
polling daemon still return a NVOT_SUCCESS return code but the color of the
icon on the map associated with the nvotChangeVertexStatus( ) call no
longer changes.

3.) Once this happens, I've performed ovstop/ovstart on that particular
polling daemon which then hangs in the nvotInit( ) call - it just never
returns.

4.) I then close the NetView GUI and restart it.  It is then
"synchronizing" forever.

5.) I then have trouble closing the GUI and often get a core file -->
/usr/OV/PD/cores/ovspmd/core

5.) I can only get things to work again by killing the GUI and performing
ovstop/ovstart.


I've debugged the polling daemon and it looks like the parameters I'm
passing to the NetView calls are always OK.  What else could the problem
be?
