Jason,
Well first we would want to know what event is going to create
a situation where the flag should be removed, new traps, specfic traps,
what? So if we receive BGP traps from a device in the smartset, run
an action to remove the flag.  This could easily be done from a ruleset,
but we would need more information about what should cause the flag
to be removed.

Agreed, but how is the flag on the device being removed/un-set?  From my
understanding of Leslie's email, it takes an operator action to un-set
the flag.  How does an operator know if X number of BGP traps have been
received in Y amount of time?

If membership in the smartset requires that flag to be set, once the flag is removed the device should be removed from the smartset. I am not sure of the timing of this,

but I would think within 5 minutes or so that device should be removed.

There is a lot of good information in here.  I guess my only question
would be is how are the devices removed from the smartset?  Looking at

your information below it seems the operator needs to run the Trap_Flag_Clear.sh (highlight nodes / OVwSelections) in order to clear

the condition. From what I understood from the original problem statement is that after a period of time, the devices should be removed automatically.

   I do that sort of thing like this:
   1) add a field to my custom fields file /usr/OV/fields/C/My.fields
   Field "My_Trap_Flag" {
           Type    String;
           Flags   locate, general;

   }
   Run 'ovw -fields' after messing with a fields file.
   2) In trapd.conf, define the traps of interest as having a trap
   source of 'Y' instead of the usual 'A' or 'u'
   3) Make a Netview ruleset that with an Event Attribute cube that
   checks trap source for 'Y' and invokes an action
   '<path>/TrapFlag.sh -set $NVA'
   4) Make that ruleset run in the background
   (/usr/OV/conf/ESE.automation)
   5) write a little script TrapFlag.sh that uses nvdbimport to set
   the field 'My_Trap_Flag' to TRUE for the node that the trap is

from.

   6) On the reports menu (/usr/OV/reports/C) add two scripts to call
   that script: TrapFlagSet.sh and TrapFlagClear.sh

   Trap_Flag_Set.sh
   #!/bin/ksh

# Set trap flag to True for the selected nodes. name=$(basename $0)

   xnmappmon -geometry 680x500 -commandTitle "$name" \
      -commandHeading "Setting Trap Flag to TRUE for Selected Nodes "

\

      -cmd <path>/TrapFlag.sh -set $OVwSelections

   Trap_Flag_Clear.sh
   #!/bin/ksh

# Set Trap Flag to false for the selected nodes. name=$(basename $0)

   xnmappmon -geometry 680x500 -commandTitle "$name" \
      -commandHeading "Setting Trap Flag to FALSE for Selected Nodes

" \

      -cmd <path>/TrapFlag.sh -clear $OVwSelections

   Users can execute those functions against one or more nodes
   selected on the map. Usually they would only use the clearing one.
   But the setting one is handy for testing.

   The job of the TrapFlag.sh script is to generate an import file
   that looks like this:
     Selection Name,My_Trap_Flag
     nodename,TRUE  (or FALSE on the clear)
   and run nvdbimport to set the values for the nodes selected on the
   map, or indicated by the rule. See the man page for nvdbimport.
   There are samples in /usr/OV/conf/nvdbtools.

   Then make your problem smartset include the criteria " ||
   My_Trap_Flag=TRUE

   The operators will know that green things in the problem smartset
   are there because of traps. They should look up the events for
   that node to see what they are. I usually provide another function
   on that reports menu that does a grep in trapd.log for the
   selected node. You could do the grep right from the script in
   /usr/OV/reports/C, but I usually have it all another one in my
   custom scripts directory. The reason for this is so I can offer
   the same function to web console users as I do to the Motif users.

   Jason,

   I assumed that if we set attribute 'IP Status', then it would get
   reset the
   next time NetView polls the device. If we set another attribute,
   then I
   assume we will have to reset manually, or use a clearing trap to
   reset the
   attribute. Can an attribute be set to clear after a certain period
   of time?

   How would you suggest that we do this?

   Thanks.

   It can be done (not sure how with smartsets though).  The theory
   being when
   a BGP trap arrives, set a certain status or set some other

attribute.

   However, when do you toggle the other way?  Meaning, after what
   interval do
   you want a router to be removed from the smartset?

   Hello,

   System information:
   OS - AIX 5.1
   NetView - 7.1.3
   FixPack3

   We are currently using a Smartset to view Routers that are either
   down or
   unreachable. Here is the Smartset rule: (('IP Status'='Critical')
   || ('IP
   Status'='Unreachable')) &&
   ('isRouter'=True)

   Besides "Critical' and 'Unreachable', we would also like this
   Smartset to
   display routers that send BGP traps to NetView. Is there any way
   to have an
   incoming SNMP trap change the value of 'IP Status', or any other
   object
   attribute? Is this the wrong use of a Smartset?

   Thanks.
