This helps you to track the network traffic and offers tools to search and drill down to the root cause of the problem. Popular troubleshooting issues that Wireshark can support include dropped packages, latent problems, and malicious network activities. You can track network traffic in real-time by using this free program and it is also the best way to troubleshoot issues within your network.
