\ List,
You
were correct, things worked as expected last night, I can only assume human
error as I replaced $A with $2 in automated action and got the correct host
name. As state my snmptrap is probably the cause.
Regards and Thanks
Peter
I, for one, am having a very hard time following this, and based on the
seven years I have spent working with distributed NetView, I am having an even
harder time believing that something is broken here. I really do work in
this area every day.
All NetView
traps, including the snmpCollect Threshold Exceeded trap 58720263 should
have the hostname of the device they are about in varbind 2, which you
reference in trapd.conf and pass to ovactiond as "$2". And they all have
a minimum of 5 variables. Your snmptrap script has neither of those and
so I doubt that it truly represents what is being sent by NetView itself.
The "threshold exceeded" message should be $3 not $2. This is as
documented in Appendix A of the NetView for UNIX Administrator's Guide.
My suggestion is that you configure this
trap in trapd.conf (using xnmtrap) so that it says $* on the Log Message line.
This will cause all the variables to be echoed to the log and the events
window in numerical order. If it truly is that case that a real
NetView event does not meet both these criteria as I have stated then you
indeed have a bug and should contact Support immediately.

List,
Ive done some testing on this issue
and I keep getting differences between
the variables.
Im using the
following to simulate traps entering into the system
snmptrap 1.1.1.1
.1.3.6.1.4.1.2.6.3 2.2.2.2 6 58720263 0
..1.3.6.1.4.1.9.2.2.1.1.12
integer 1 0.0 octetstring "threshold exceeded" 0.0
octetstring "locIfInCRC"
.1.3.6.1.4.1.9.2.2.1.1.12 integer 1
Where 1.1.1.1 is my
netview box and 2.2.2.2 is my monitored device
Using the $2 variable I
get threshold exceed
Using the $A variable I get the correct host
name
When threshold monitoring fires (ie not using the above script),
using $A I
get discrepancies in the value, and $2 simply carries threshold
exceed. The
popup notification contained the host where the collection was
targeting,
whilst the value passed over to automatic action contained the
Netview Host
box.
I've double checked the sequence of variables all
they are both the same.
Any thoughts would be appreciated,
alternatively if someone can think of
another way to generate an email
based on a threshold being passed I would
appreciate it.
Regards
Peter

Ran into something similar. This is from memory.
My test box is
overwhelmed at the moment so cannot verify.
IRRC, $A is the name of the
node that sent the event. For a
Netview event, that's the Netview server;
For an externally generated trap,
it's the hostname of the device issuing
the trap. As James suggested,
use $2 as appropriate, or $NVATTR_2 in a
script called by a ruleset.

I've seen this kind of problem at least a couple of
times. One time when I
saw this I traced it to a name resolution
problem. I don't remember the
exact details anymore, but the
situation was something like this: NetView
had the hostname of the agent in
its database, but the DNS server was down
and NetView couldn't resolve it
back to an IP address. As a result,
NetView substituted its own
hostname/IP in the agent address field. This
was with NetView 5.x on
AIX.
There has been one other time when I've seen this but wasn't able
to find a
cause.

Please respond to
nv-l
List,
I have AIX5.1 with
NV7.1.3,
I'm using threshold checking to monitoring errors on an array
of cisco
routers. This works correctly and re-arms the monitor when the
condition
meets, however I seem to be having a slight problem with trap
customisation
(IBM_NVDCOL_EV).
In the pop up notification I have the following
$A $3 $4 $+1
which works correctly, ie $A displays the hostname of the
device with the
errors, a router.
In command for automatic action I have the
following
/home/$path/script.sh $A $3 $4 $+1
But the value in $A
is the hostname of my Netview box and the not the
monitored
device.
Any thoughts would be
appreciated.
Regards
Peter
