If you have NetView, you have MLM, though I appreciate that doesn't mean
to say that you use it! I often install an MLM on NetView explicitly
to give me the functionality that you want.
The Agent Policy Manager (APM) is an app off the Tools menu and gives
you a way to customise something very similar to the Data Collection and
Thresholds app. So, you will need to specify a name (the bit that will
go after the hostname: in the new TRAP that you so rightly surmise will
be created with snmptrap - I think Leslie added an append with this).
You also specify to APM the MIB variable to collect - we don't care
about this as what we really want is the icon that we can control via a
different TRAP. I use .1.3.6.1.2.1.1.3 which is sysUpTime which I poll
once every 42 days (why not?), with a threshold >1 and a rearm < 1 - as
I say, you don't care about this but it has to be a legal OID.
The good bit is that you get to specify a SmartSet as the target for
this Policy - otherwise you would have to hand-create all the icons
individually. When you distribute, APM (which is implemented as the c5d)
works out which MLMs to send this policy to to include all the
destinations in your SmartSet. If you only have 1 MLM co-located with
your NetView, that's the guy that will do your nominal data collection
polling.
Don't forget to start your APM c5d daemon from serversetup Configure
menu - it's not started by default. After you have restarted your NV
GUI you should see 2 new top-level icons, 1 for APM and 1 for MLMs. You
don't really care about either but it is a good confirmation that c5d is
configured.
When you distribute your policy, every node in the SmartSet you
specified should have a new icon with the policy name you gave -
obviously you can have lots of different ones if you want to monitor
lots of services. Once you've got the icons, you really don't care
about MLM and APM again.
I attach my little gen_user2_trap.sh which I use from Tivoli DM to do
exactly the same sort of thing you want. In my script, I assume that
the APM you created was called Tivoli_DM. Although the description of
the change status trap doesn't say so, you can pass all sorts of stuff
on the trap varbind3 as you can see.

Good information, a clarification may be in order.....
1) Create a new icon inside the node icon of the relevant devices. I
like to use the APM and MLM to do this as you can then use a SmartSet to
specify which nodes get the new icon.
===> When you say "create an icon" do you mean "add an object" from the GUI? We
do not have MLM and I'm not sure what APM would be used for here. Can you expand a little?
The MIB variable you use in the
APM setup is a dummy - I generally use something like sysuptime > 1.
===> This is the part that I'm not sure what you mean. I have no APM experience so I will go read the book a bit.
2) Customise your specific TRAP so that it generates a new NetView
Change Status TRAP (58916871) on the Selection Name that you create by
catenating the Node name from the original TRAP with the new icon name
that you supplied when you created the icon with APM. For example, if
your original TRAP came from node fred and your APM icon is called
myService, your Selection Name needs to be fred:myService. I generally
change status to User1 or User2, depending on whether I want the new
icon status to propagate up to the Node level.
===> I assume you use the SNMPTRAP command to do this? Another new thing for me
to work with but it's pretty straightforward.
3) This way, you get an icon that represents your service, that changes
colour and, if you use User2 as your "bad news on the service colour",
you can get a marginal colour on your node icon, which seems an accurate
representation to me. Of course, if the interface of the node also goes
down, then the whole node will go Critical.
Does that help?

Greetings listers
Netview V7.1.3
Solaris 2.8
We currently receive and process traps froma cisco content switch.
They are syslog traps that contain only the name of the service and
the state:
Web Application Event: Service Transition -* **Service:lexlw5se
State:alive* @ Tue Apr 22 03:33:06 2003
The section in red is the part that is stripped out of the syslog trap
and used for notification. What I want to do however, is have a "node"
in NetView that turns red when the service is down and then green
again when the service is active. I have a perl script that can
execute the necessary functions but I'm unclear on what those
functions would be.
My original thought was to add a node to the map with that service
name and then use the "event" command to mark it down but that does
not work (I think because status events have to come through netmon
and the event command really doesn't change the status on a node.)
In my environment I don't need to use nvsniffer or any other tool to
check the status, I merely need to handle the incoming traps and
change the status of the "node" based on the trap. Anyone have
recommendations on how to go about this?
