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

Sorry, but no.
There is no facility to pass on "cooked" data. And you are correct those other formatting techniques have nothing to do with this issue either, nor does the AdditionalLegalTrapCharacters. But I am curious. Are you saying that the varbind "$3" is empty when it gets to ovactiond? Or does it still contain one or more hex characters? Or is that exactly the problem, that you cannot tell which is the case?
Off hand, I cannot think of a way out of your predicament. If what you want to do is simply print the message for analysis later, then you could use the
roundabout method of capturing the formatted string as an Additional Action in nvevents. As the man page for trapd.conf shows, you can capture the formatted message of an event in the display as $MSG and use a script to print that. But I don't see how to pass it on to ovactiond for anything automatic.

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.

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.
