No, isNode=True will give all of the nodes, but you will only ever be able to get one IP address off a node using nvUtil.  So it depends what you are looking for.

thanks.  what about how to find the nodes at all?  is "nvUtil e isNode=TRUE" too restrictive?  
 
thanks again

Try
   nvUtil e '(isInterface=True)' '%IP Address%,%Selection Name%,%SNMP ifPhysAddr%'


For the sample interface below, that would give

172.16.5.20,thisnode.mydomaincom:eth1,0x001321AF82F5


# ovobjprint -s thisnode.mydomain.com:eth1

               OBJECTID                SELECTION NAME

See also that tool script 'macem.sh' I left there that looks up the mac in Netview for a list of IP addresses.

[NV-L] Discovery questions







Oh gentle learned people, I have some questions for a discovery that we are doing:

1.  i'm scanning by lists of whole ranges of ip's, listed ip by ip in the seedfile.  Some things may not be in dns and I'm looking for all things on that network segment, be them servers, routers, switches, etc..  They may or may not have snmp enabled.  I was teasing this data out of the database with "nvUtil e isNode=TRUE" but is there a better way?

2.  if snmp is enabled, is there an easy way to get all the mac addresses of all of the interfaces of a device?  

Thank you in advance
