How to Use SolarWinds WAN Killer to Test Network Performance
SolarWinds WAN Killer is a network traffic generator and stress test tool that can help you simulate realistic network conditions and measure the impact of traffic spikes on your devices and applications. In this article, we will show you how to use SolarWinds WAN Killer to perform a network load test and analyze the results.
What is SolarWinds WAN Killer?
SolarWinds WAN Killer is a module in the SolarWinds Engineer's Toolset, a suite of over 60 network management tools that can help you monitor, troubleshoot, and secure your network. WAN Killer can generate random IP traffic with customizable parameters such as IP address, port number, packet size, bandwidth percentage, DSCP, and ECN settings. You can use WAN Killer to test the performance of your network devices, links, and applications under different traffic scenarios and identify potential bottlenecks or issues.
How to Use SolarWinds WAN Killer?
To use SolarWinds WAN Killer, you need to install the Engineer's Toolset on your computer and launch the WAN Killer tool from the Toolset Launchpad. You also need to have access to the target IP address or hostname that will receive the traffic generated by WAN Killer. Here are the steps to use SolarWinds WAN Killer:
Enter the target IP address or hostname in the Destination field. You can also select a target from a list of previously used destinations or from a network discovery scan.
Enter the port number or range that will be used for sending traffic. You can also select a common port from a drop-down list.
Enter the packet size in bytes or select a common size from a drop-down list. The packet size affects the bandwidth utilization and the network overhead.
Enter the percentage of bandwidth that will be used for sending traffic. You can also select a percentage from a slider bar. The bandwidth percentage is calculated based on the interface speed of your computer's network adapter.
Optionally, modify the DSCP and ECN settings to change the quality of service and congestion notification of the traffic. You can also select a common DSCP value from a drop-down list.
Click Start to begin sending traffic to the target. You can monitor the traffic statistics such as packets per second, bits per second, and packets sent and received on the tool's dashboard.
Click Stop to end the traffic generation. You can also set a timer to automatically stop the traffic after a specified duration.
How to Analyze the Results of SolarWinds WAN Killer?
The results of SolarWinds WAN Killer can help you understand how your network devices and applications respond to different traffic loads and conditions. You can use other tools in the Engineer's Toolset or other SolarWinds products to analyze the results of WAN Killer. For example, you can use:
The Response Time Monitor tool to measure the latency and availability of your network devices and applications.
The SNMP Real-Time Graph tool to monitor the CPU, memory, and interface utilization of your network devices.
The NetFlow Traffic Analyzer module in SolarWinds Network Performance Monitor to analyze the source, destination, protocol, and application of your network traffic.
The Network Configuration Manager module in SolarWinds Network Performance Monitor to backup, restore, and compare the configuration files of your network devices.
SolarWinds WAN Killer is a powerful and easy-to-use network traffic generator and stress test tool that can help you simulate realistic network conditions and measure the impact of traffic spikes on your devices and applications. You can use SolarWinds WAN Killer to perform network load tests and analyze the results with other tools in the Engineer's Toolset or other SolarWinds products.
