For what purposes have you used network traffic monitoring tools?

Tools for monitoring network traffic (e.g., Wireshark, tcpdump) are used for:

• Debugging network interactions between client and server.
• Analyzing and identifying issues with performance or packet loss.
• Checking the correctness of protocols and the format of transmitted data.
• Ensuring security, detecting suspicious or unauthorized connections.

For example, when testing an API, you can listen to requests and responses to ensure that data is transmitted correctly and in the proper format.
