Nexus monitoring, device recource metrics

Question

Hello
I'm looking for Nagios/Nexus Plugins and lesson learned is, that there seams to be currently (2011/10/20) nothing at all.
So I want to start with this and want to ask the experts about the basics of Nexus monitoring.
What is the best practice to monitor Nexus device recource metrics? NetConfig, SNMP, SSH with preshared key?
For Netconfig are there any documentation how to can use it with Perl?
If SNMP should be still the best, are this OIDs known or what should be the best method to get them out?
Are there SNMPv3 issues e.g. with views?
How to find out the Nexus OID's for its IOS-equivalents, e.g.
"Voltage" => ".1.3.6.1.4.1.9.9.13.1.2",
"Temperature" => ".1.3.6.1.4.1.9.9.13.1.3",
"Fan" => ".1.3.6.1.4.1.9.9.13.1.4",
"PSU" => ".1.3.6.1.4.1.9.9.13.1.5"
ModuleState ?
How to find out OIDs for special CLI commands, e.g. traffic class violations:
sh policy-map interface control-plane | egrep "class-map|violated"
    class-map copp-system-class-normal (match-any)
        violated 5394687638 bytes; action: drop
If Netconfig is to complicated and finding Nexus SNMP-OIDs is an unresolveable neightmare, can SSH with preshared key could be an oportunity for permanent monitoring?
many thx in advance for your hints and ideas,
Steffen

If this is not working, it is only that the essential device package seems to be missing. please do the following :
1. Download all device packages available for LMS server :
     Step 1: Open command prompt on server.
     Step 2: Run following cli command :
psucli -p rme,cmf,dfm,cvw,upm,cm -download -dst C:\test_download -all
**Created test_download dir or name some existing.
     Step 2: Check the downloaded files, if they are in diffrent folders inside download dir, copy all of them to a common folder and run this command :
psucli -p rme,cmf,dfm,cvw,upm,cm -install -src D:\test_download -all
**use directory you downloaded packages to
     Step 4: Check the device if it shows nexus 7004 information or not.
