James,
Thanks
this is helpful, I'm clear on what I need to do.

The answer to your first question is in the trapd.log. All the numbered
varbinds and their contents are shown there. So no, there is no one varbind
which contains the trapd.log message. That message is a construction and if
you want to use it in your script, then you have to reconstruct it, just as it
done by trapd when he combines the variables and the fixed text that are found
in trapd.conf for this event log message. Sorry but this is a programming
exercise.
As for the rest, I simply don't understand what you are
driving at. A ruleset should never end in an in-line action, unless it is on
Windows. Is there more to come? An in-line action is executed by nvcorrd
himself on UNIX, and if you write an in-line action, then all of the event
processing in your event windows and in your TEC adapter will be held up while
nvcorrd executes your script. That's usually a bad idea performance-wise
unless you can guarantee that your script will finish in under ten seconds.
Actions, as opposed to in-line actions, are executed off-line, by actionsvr,
and thus do not hold things up.
A script is a script. Why would you
have to pass in the string as a parameter when you can just rebuild it inside
the script? Can't you just build a string by concatenating variables and text
until you have what you need? I'm afraid I don't follow. Can't you do
something like this
mystring="The enclosure $NVATTR_5 fan in rack
$NVATTR_3 has been"
<full_path><my_other_command>
$mystring
right in your script?
I think you are making this
harder than it needs to be. Perhaps this will help.
What's going to
happen in the Action node or In-line action node is this. The daemon executing
it is going to build a script environment as a temp file internally, like
this:
#!/bin/ksh
export NVATTR_1=OA-001635C6764A
export
NVATTR_2=0
export NVATTR_3=USE063471P
export NVATTR_4=
export
NVATTR_5=enclosure460
export NVATTR_6=USE6341KKS
export NVATTR_7=10
export NVATTR_8=
export
NVATTR_9=83
.
.
<various other exports listed in the manual, NVE,
NVG, NVS, etc>
.
<yourscript> <your hard-coded parameters
>
exit
Then it's going to fork this puppy as a process and
execute it.
What you have to do is write "yourscript" to access these
exported environment variables directly as $NVATTR_n, substituting them where
you need them. That's the programming assignment. There is no hidden magic.
All we are doing is giving you the opportunity to take the contents of a trap
off the wire and have a script of your own design execute using them whenever
that trap comes in. The rest is up to you.

Hi James,
Thanks for the info.
I don't think I was clear in what I need exactly.
1. Is there a variable that exists that contains the whole
message string as it appears in trapd.log. I know the $3 and $5 are accessible
individually
via varbinds. I wanted to pass
this whole string exactly in one variable.
"The enclosure
enclosure460 fan in rack USE063471P has been"
2. I know that I can modify the automated action to pass the
string above directly to a script. This will not work for me because my
rules
require this sequence "Event stream-->
Smartset query --> Trap match--> Inline action
script"
Is there a way to encode the string
in a variable and pass it along with the varbinds which I can then use in my
inline action script.
I've seen a previous post
of a perl script that interrogates trapd.conf to get the string, but I was
hoping I didn't have to go that route.

You reference those as $NVATTR_3 and $NVATTR_5 in the script and
execute the script in a Action node. When the Action node fires it will
create a new shell with root authority and export all the trap variables
in this way. This is covered in the Chapter on Event Customization in the
NetView Admin Guide. Look there for more details.

Thanks Francois,
If I
execute a script via a ruleset how does the script get the vars $3
$5?

You can configure an automatic action for that trap with the
parameters you need ($3 and $5) in xnmtrap. You can also execute a
script in a ruleset.

How
do I get the trap description string as shown in the trap.log sent
to a script?
I am working with an HP c-class device using compaq mib
.1.3.6.1.4.1.232 on Netview 7.1.4
The trapd.log shows:

enclosure460 fan in rack USE063471P has been removed.
The varbinds look like this:
