Network Traffic Test

This test auto-discovers the network interfaces supported by the EMC VNX Storage system and reports the rate at which network packets and data were transmitted/received over every discovered interface, and the errors encountered by each. This way, the test sheds light on the slow, error-prone, and congested (in terms of level of network traffic) network interfaces of the EMC VNX Storage system.

Target of the test : An EMC VNX Unified Storage system

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each network interface supported by the EMC VNX Unified Storage system.

Configurable parameters for the test

Parameter	Description
Test Period	How often should the test be executed.
Host	The IP address of the storage device for which this test is to be configured.
Controller Station IP	The Control Station is the management station for the VNX for File system, and enables control and configuration of the system. The eG agent uses the CLI that runs on the Control Station to monitor and manage the performance of the VNX for File system. To enable the eG agent to use this CLI, specify the IP address of the Control Station in the Controller Station IP text box. By default, the IP address of the host will be displayed here.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Packets received	Indicates the rate at which the network packets were received over this network interface.	Packets/Sec	A high rate of incoming and outgoing network packets could indicate that the network interface is experiencing high levels of network traffic.
Packets sent	Indicates the rate at which the network packets were sent over this network interface.	Packets/Sec
Inputs errors	Indicates the rate at which network input errors were encountered during data transfer over this network interface.	Errors/Sec	Ideally, the value of both these measures should be 0. Comparing the value of each of these measures across interfaces will introduce you to the error-prone interfaces.
Output errors	Indicates the rate at which output errors were encountered during data transfer over this network interface.	Errors/Sec
Data received	Indicates the rate at which data was received over this network interface.	KiB/Sec	A high rate of incoming and outgoing data could indicate that the network interface is experiencing high levels of network traffic and is probably consuming bandwidth excessively.
Data sent	Indicates the rate at which data was sent over this network interface.	KB/Sec
