There are multiple tools available to capture packets.

You can capture directly on the host using pktcap-uw, which will allow you to capture traffic at various points in the stack.  The captures can be exported to file readable by Wireshark.

VMware KB: Using the pktcap-uw tool in ESXi 5.5 and later

You can also leverage port mirroring to capture traffic passing through the vDS which will send traffic to a monitoring workstation as well as other options.

You can also capture the traffic from the physical wire, on the side of the physical switch if you physical switch by using port mirroring, sending traffic to a monitoring workstation.

Pages 47 through 59 of the NSX-v Operations Guide do a good job detailing the procedure to leverage port mirroring.
