NetXMS Support Forum

Hello Everyone,

          This is my really first in depth try at using NetXMS, I have a db server in stalled on Windows Server 2008 R2 and I have the NetXMS Server installed on another node/host with Windows Server 2008 R2 and after a few hiccups with the install I finally got to configure it but now I am seeing some odd stuff in my Alarms, NetXMS is a VM and The Database is a Physical Server. Please see the attachment for the anomoly I am seeing.
These appear to be some type of tunnel but I can't figure out what purpose they are for.

[Minor]   CFMON (NetXMS)   Interface "Local Area Connection* 8" changed state to DOWN (IP Addr: UNSPEC/0, IfIndex: 11)
[Minor]   CFMON (NetXMS)   Interface "Local Area Connection* 8" changed state to DOWN (IP Addr: UNSPEC/0, IfIndex: 11)

[Minor]   cfdatabase (Database)   Interface "Local Area Connection* 8" changed state to DOWN (IP Addr: UNSPEC/0, IfIndex: 11)

I am not sure what this is telling me. There is only 1 NIC in each system, So I can't figure out why this is going on.

Thanks in advance for your help,
Michael

Hi Michael,

Quite a few Windows servers I am monitoring show such "Local Area Connection* <N>" interfaces, which are not active interfaces on the system itself.
I didn't dig too deep into it, but made a guess that these are probably inactive networks that Windows has saved somewhere (e.g. a different network connected during server setup or similar). The only thing in common was the "*" in the name, so I filtered those out using a script in Hook::CreateInterface in the Script Library.
In our case, I did the same for isatap and Teredo (and a few other) interfaces, as we don't need to see those either.

See below for an example using the three interfaces mentioned above:

if ( $1->name ~= "^isatap" ) return false;
if ( $1->name ~= "^Teredo" ) return false;
if ( $1->name ~= "\*" ) return false;
return true;


Cheers
