Hey Guys,


I think it's a stupid question but how can I log the traffic of an ethernet port of a server?
Could somebody show me how to do this?


thanks

Usually bandwidth information can be made available through SNMP, but you'll need to provide more details about the server (vendor, operating system, version, possibly NIC type) to have a chance of figuring out the specifics.

sorry, here are the information:

It's an VM which is running on a XenServer 5.5
The OS is Windows 2003 R2 (32bit)
The NIC is a "Citrix XenServer PV Ethernet Adapter"

I think the hole thing is running on a Dell PowerEdge 2950.

It looks like this should work pretty much "out of the box" as far as XI is concerned. Take a look at this thread on the Citrix forums for some information you may need to make sure your XenServer has SNMP enabled, and then run the SNMP wizard found under the Configuration tab in XI with the settings you configured on XenServer.

My problem is, that I don't know what i have to type into the SNMP wizard to get the traffic of the server's NIC.

I don't know the commands like "ifOperStatus.1" and so on.


Do you have a hint to get these information.

Okay, after looking into it, apparently SNMP actually only reports a counter (see the list here), not a current bandwidth, and you need other tools to calculate the bandwidth, so it's a bit more complicated than what I said. As far as I can tell, our wizards don't actually quite support doing this correctly for devices other than switches, so I'll have to file a feature request for that.
