Are
you sure that the data you are sending is formatted correctly in the ASN.1/SMI
trap?
If I
were in your shoes I would circumvent nvevents and get my info directly from
trapd. This will allow you to look directly into the trap and pull what
data you need. You can do this using the Netview API 'OVsnmpRecv'.
Take a look at /usr/OV/prg_samples, you will find examples
there.
Remember vardinds are a union structure so you need to look at the type
before making a determination of the data content. Varbind types as
defined by Netview (that I use) are:
case ASN_INTEGER:
case ASN_U_INTEGER:
case ASN_TIMETICKS:
case ASN_GAUGE:
case ASN_COUNTER: case
ASN_OCTET_STR:
case ASN_OPAQUE:
case ASN_IPADDRESS:
case ASN_OBJECT_ID:
case ASN_NULL:

All,
I do
pass all the variables within quotes as in : <myscript> "$1" "$2"
"$3" "$4" "$5".
> What
you are passing to your script is raw data from trapd. That is exactly the subject of this question : is there
a way to instruct trapd and ovactiond to pass "cooked" data to a script ?
The NV documentation explains when to use $1, $-1, $+1,
etc but I could find nothing about
converting a string of bytes (e.g. 0x08 07 02 04 01 01 02 01 : from an actual
device) into something that a script
can work with, i.e. which can be unescaped. I guess that even AdditionalLegalTrapCharacters could not help
here.
Regards, Phil.

What's in the display window of nvevents is a
construction. nvevents has already set aside a buffer and interpreted it.
What you are passing to your script is raw data from trapd.
If
it contains blanks, then you must enclose it in quotes, just as you would any
other script input on the command line. You have to
pass <myscript> "$3"
not just <myscript> $3 or
the shell will pass only the first word of $3.
In
general it doesn't hurt to enclose all of your variables
<myscript> "$1" "$2" "$3" "$4" "$5" when
you don't know what form the incoming data will take.

[nv-l] How to pass Octet String trap parameter to
script ?

All,
AIX
4.3.3 ML10 + NV 7.1.3 + popular patches.
I need to provide a script
with the parameters found in a trap. $1, $2, etc work fine for
integers and strings but doesn't for Octet Strings.
It
seems that the bytes are passed (and escaped for most of them) by
ovactiond. Is there is way to get the bytes string as
displayed in the events window ?
( i.e. a string like "0x01 12 34 ab
..." )
Best regards,
Philippe.
