Well, what you want to do and what is possible may be two different things.  The
two Ruleset nodes, set and query global variables require that you hard code
into the ruleset at the time you write it what the variable name will be, and
how the value will be affected (set to some literal, set to some variable, or
incremented or decremented).    Since these are set at "createle time" (or
"compile time" if you will) and not at "run time", there may be no easy way to
do what you want without using your own script.

You could try making the variable name equal to $NVATTR_2 (the hostname) for
example and see if that works, but I don't guarantee it.   Most of the ruleset
mechanisms were designed to be very simple manipulations to you would not have
to write code, but if you want to do something they do not provide, you must
write your own scripts instead.

éf. : [NV-L] Global Variable Names


Does your trick refer to doing it in a shell script?? What I want to do is
establish the variable in the actual rule - is in the Set Global Variable node I
want to create a variable that takes the name of the device that the event
refers to and then assign a value for it.

Hi Gavin !

There is a trick to do so but it is quite a strange way to do it.
If i understand well you should do it this way:

echo $var | read $(echo $NVATTR_3).
(let assume that "var" is the data you want to set in what you named $$NVATTR_

I explain: "read" is an Aix command that set a data with a stream comming from
<STDIN> wich name is the first argument in the command line.
Here i do $(echo $NVATTR_3) so the shell return "fred" because $NVATTR_3 is

So:    echo $var | read $(echo $NVATTR_3)   ==>  echo $var | read fred
Then if you run "echo $fred" you will see the value  in "var".
The $fred data now exists.
