Re: [nv-l] trapd.conf and custom slot name

You cannot alter the contents of a trap
variable in a ruleset, nor any other way.

If you want to add a varbind or alter
its contents, then basically you have to use a ruleset or a script run
by ovactiond (from trapd.conf as a command for automatic action)  to
issue a new trap of your own making with your additional or altered varbind
in it, typically with the snmptrap command.  Then you send that to
TEC or to the event console rather than the one you received.   

By the way 58916867, Interface Down
has 8 varbinds, not five.  The documentation, the Appendix to the
Admin Guide,  was upgraded to reflect this in 7.1.4, but the trap
itself has had more since 7.1.

Could anyone give an example of how I can set an varbind variable from
an external script  ? 
Maybe call an Inline command from a ruleset ? 

When forwarding a internal trap like 58916867 (interface down) it only
contains 5 varbinds, say you want to add another information to that trap.

If I understand what you said, you added a field to the object in the NetView
database.  Well, there is no mechanism provided in trapd to extract
that field.  He has no way of knowing about it.  What you can
do in trapd.conf is manipulate the varbinds that are sent with the trap
itself, but you cannot add anything new except fixed text, or combinations
of existing varbinds using the PRINTF syntax. 

Either you will have to provide one an extraction mechanism yourself and
make it part of your TEC ruleset, or you will have to find what you want
in the trap varbinds.

Subject	[nv-l] trapd.conf and custom slot name

Hi, 

A question when integrating  Netview 7.14 with TEC 3.9

Reason for my question is that we want to use short nodename i Netview
and a longer nodename i TEC. 
So we have added an extra field at each object i netview, called tec_nodename
where the long name is kept. 

Now I want to transfer the content of field "tec_nodename"  in
slot map "nv_var15"  to TEC 

So the big question is what syntax should I use in trapd.conf ???

I have tried 
      nv_var15 tec_nodename 
but the result is that nv_var15 contains the fixed text  "tec_nodename"

Any suggestions ........
