Top VM:Host Pairs (10164 / 20164)

Description

This Module reports top network conversations in VM environment. A network conversion is a series of data exchanges between two VM:Hosts (VM source IP:Host source IP and VM destination IP:Host destination IP), over the same protocol (TCP or UDP), and going through the same vSphere Distributed switch (VDS) (VxLAN ID). The number of exchanged bytes and packets are summed up.
The Module determines which VM:Host is a client and which is a server as follows: a server sends more traffic (bytes) than a client.

Parameters

Parameter Name
Description
Comments

N - number of reported host:vm pairs
The number of top hosts reported per NetFlow exporter
min = 0, max = 100000, default = 50 (0 indicates all hosts are reported)

Input
