Thanks Leslie..


I am going keep this note as keeper, as I haven’t tackled the other box yet. As now I need to figure out how to publish a read only ip map and ensure that map is synchronous with the main netview map. (I think some one just went through this a few days ago, and our set up is similar Unix box no video interfaces etc.)


However I am happy to say....


We are finally seeing a decent map on the netview box that has just the routers. Things did not line up until we placed all devices in snmpd.conf, we stop and start nekton to force a db check of known devices vs. seedfile and few minutes later we had very few items in ip map and everything else got slotted automagically : - ).


The timing was perfect as we saw a rash of ISDN link up alerts on TEC console and could not isolate root cause, but about 20 minutes later, graphically we could see who was impacted ( we have polling set to 20 minutes). As it turned out something happened at a local CO and caused outages at 15 geographically different sites in different ospfs, so really in this instance no correlation rules could of helped but graphically seeing in was very pleasing.
I think my issue was not understanding the relationship with the snmp config panel and the map. Although we had devices in ip map and some in smpd.conf they were not slotted correctly as we liked, and when we had all of them in there  everything was OK. Documentation is not clear on this relationship or am I way on left field on my assumption ?? 
I Still have a lot to learn......
Regards, and thanks

So you are looking for a way to generate a location.conf with a map that has already been layed out and cleaned up. That is not what this tool is for.

I've made plenty of location.conf files programmatically based on the customer's knowledge of the network. You know what your general heirarchy will be, and you know which routers will be in them. You can start with that. Edit the file and enter the heirarchy of locations, like:

A501 255 Site2
A502 255 Site2

etc. where 255 is just a placeholder dummy network. Under each subarea, enter the names of the routers that go in there. You can also make entries for the subnets assigned to that OSPF subarea. You can retreive the subarea assigments of routers with mib appls as well. For instance,

# get_ospf_if.sh
# A convenience routine to display OSPF interfaces for a node
# at the commandline or from a script.
# Invocation: get_ospf_if.sh $NODENAME <optional community string>
#set -x

if [ -z "$NODE" ]
then echo "syntax is $0 nodename "
if [ -z "$2" ]
then COMM=""
else COMM="-c $2"

/usr/OV/bin/mibtable \
     -table  "." \
     -fields "ospfIfIpAddress=1:15,ospfIfAreaId=3:15,ospfIfAdminStat=5:8 " \
     -node $NODE $COMM  | grep -v disabled | grep -v MIB | grep -v ospf | sort -t. +4
exit 0

Do the File..New Map thing once and use that map as a starting point. Then it is much easier to manually put everything away.

But don't stop there. Once you have it roughly arranged, use the  script to produce a new location.conf . Look at that output. It will have many specific entries. You then can generalize them into ranges. Those ranges (as opposed to specific entries) are what should lessen the administrative burden later on.

Re: [nv-l] locations

One way or another, you are going to have to do the work. Try creating
the location.conf file on the fly. This is not that complicated, Create
a New Map, check it, add more stuff to the location.conf rinse, repeat.
You can zoom the map down and do a few devices at a time.

You could clear your database, control discovery, and build your
location.conf as your discover more devices. This would be my real
suggestion. This way you don't discover what you don't want to monitor.
You specfically place the device where you want them via the
location.conf file. I would suggest this for anyone starting a NetView
project. You network is a complex creature and just setting NetView
loose can be a dangerous thing(as you have seen). It takes time to
build a good network and it takes time to build a good map. A good
one of each is worth their weight in gold.

You could rediscover everything and then cut and paste stuff into the
locations, controlling your discovery as above, once that is complete,
you can use script to create the location.conf. The script is really
just a way to turn the hard work of cutting and pasting into a nicely
formatted location.conf file, or a nice way to clean up the
location.conf file if it has become unwieldy as a result of repeated

I think perl 5.0 might be a problem, try perl 5.0.6(8). I have used it
on both and it worked as expected.
