[crossbow-discuss] flow statisitcs on xVM guest VNIC
While booted in OpenSolaris/xVM, I am running a Linux paravirtualized
guest which uses a VNIC automatically created for the guest. In dom0, I
am setting up a number (1 through 6) of flows on that VNIC representing
some types of network traffic I am interested in. Each flow is
identified by some remote IP address range and is created as follows:
flowadm add-flow -l vnic100 -a remote_ip=a.b.c.d/e myflow
The problem is, no matter how active the guest is on the network,
''flowadm show-flow -l vnic100 -s'' (flow statistics) shows all
zeros for
all flows. Is flow statistics supposed to work in this scenario?
''dladm show-link -s vnic100'' (link statisitcs) shows
reasonable values.

Thanks,

Hi Vasiliy, I think that was a bug in older bits. The latest code has this fixed. I tried exactly what you did on a x64 based system # dladm create-vnic -l e1000g1 vnic100 # ifconfig vnic100 plumb # ifconfig vnic100 10.1.10.6/8 up # flowadm add-flow -l vnic100 -a remote_ip=10.1.10.11/8 myflow # /opt/tools/netserver Starting netserver at port 12865 ... Shoot some traffic from the host having 10.1.10.11 addres to the destination 10.1.10.6 # flowadm show-flow -l vnic100 -s FLOW IPACKETS RBYTES IERRORS OPACKETS OBYTES OERRORS myflow 819636 1229148240 0 0 0 0 I believe this is what you are looking for. We should be pushing out the new bits very soon now.

[crossbow-discuss] flow statisitcs on xVM guest VNIC
Hi Sunay, Thank you for replying. Hmm, if I create, plumb, and bring a VNIC up myself per your example below, I can see flow statistics too. If, however, I use the VNIC created for the guest automatically, flow statistics still shows all zeros. May it be due to the fact that the guest VNIC is not plumbed or marked as "up" in dom0?

The reason we cannot capture statistics is that the flows don''t get initialized for non-DLS clients and we are tracking this as an RFE (See CR 6778531). We will look into this at the earliest. thanks ~Girish
