Hyper-V2008R2 net.if.in failure

[Golf2]

Hello all,

i´m from germany and i have a problem with a virtual machine on hyper-v 2008r2.

In Zabbix i can read every network traffic from normal servers that arent virtual machines. So Zabbix works fine.

normaly the key in the Items menu looks like
net.if.in["BASP Virtual Adapter"]

in the virtual Servers looks like
net.if.in["Netzwerkkarte für Microsoft Virtual Machine-Bus"]

I think, its a problem with the virtual network interface and / or the name of the virtual network interface. "Netzwerkkarte für Microsoft Virtual Machine-Bus". Because only in german the öäü exist.

I get the Network name with "route print" so it will be ok.

Anyone can help me?

Thx

Hello and welcome!

As from Zabbix documentation: Multi-byte interface names on Windows are supported since Zabbix agent version 1.8.6.
(https://www.zabbix.com/documentation...s/zabbix_agent)

What agent version do you use then?

Did you create this item by yourself or was it created by a low level discovery rule? I somehow doubt that the problem in your case would be in interface name due to German specific characters.

Best Regards,

Hello ingus,

i use a Zabbix 2.2 VHD Appliance.

As Agent i use 2.2.3.

I create the item by myself.
On physical Host it works normaly, only at the hyper-v clients it doesnt work.

I can check CPU Load and other stuff on Hyper-V Clients (2008r2, W7, WXP) only the network statics doesnt work.

Hello!
Does Zabbix show this item as "Not supported"?

Can you try to check this item with zabbix_get utility?
(https://www.zabbix.com/documentation...ges/zabbix_get)
On your Zabbix server run the command:

zabbix_get -s <host name or IP> -k net.if.in["Netzwerkkarte für Microsoft Virtual Machine-Bus"]

You can also try running zabbix_agentd command on your monitored host to see if maybe there is a problem with the interface name.
(https://www.zabbix.com/documentation.../zabbix_agentd)

zabbix_agentd -t net.if.list

Hello Ingus,

thx for ur help.

1. Yes i get the message "Not Supported" at the Item

2. I get the Error " Zabbix_get [3412]: Get value error: ZBX_TCP_READ<> failed: [0x00002746] Eine vorhandene Verbindung wurde vom Remotehost geschlossen.

3. If ein run the command, i get the name of networkinterfaces back but there doesnt looks like "Netzwerkkarte für Microsoft Virtual Machine-Bus".

Its "Netzwerkkarte f┬│r Microsoft Virtual Machine-Bus"

So i think its a Problem with german ü letter.

4. Now i have change the interfacename to
net.if.in["Netzwerkkarte f┬│r Microsoft Virtual Machine-Bus"]

But same error. "Not supported"

If i start ur command from 2. with the cryptic interfacename, i geht another error back. It calls
zabbix_get [3344]: Get value error: ZBX_TCP_WRITE() failed: [0x00002745] Eine bestehende Verbindung wurde softwaregesteuert durch den Hostcomputer abgebrochen.

LOL, ok problem is fixed.

Quick and Dirty
net.if.in[172.xxx.xxx.xxxx]

With the IP of the host (2008R2 virtual client) it works fine..... somtimes it will be so easy.

Thx for ur help.

Hi All,

now i have another Problem with net.if.

For a few computer my soloution works fine
net.if.in[172.xxx.xxx.xxxx]

But for a template it wont work. So i use a variable it looks like
net.if.in[{HOST.CONN1}]

The Problem is, net.if.out[{HOST.CONN1}] show me a wrong speed. They show me only 20MB/s, the first solution shows me the right speed of 75MB/s.

The variable {HOST.CONN1} used the ip from Host Agent Interface? Right? Or who can i get the right IP variable?

Thx for ur help.

The Problem is unchanged.

The Problem is unchanged.

Hello!

Please check if you have only one agent IP interface on the host that shows the wrong speed. I you have multiple agent interfaces, it is very likely that {HOST.CONN1} uses the wrong interface.
