How can I check the number of packets dropped by udp because the recv buffer is full ?

Hello, In Windows, to check the number of UDP packets dropped because the receive buffer is full, you can utilize Performance Counters. Here are the steps to view this information: Open Performance Monitor: Search for "Performance Monitor" in the Start menu and open it. Alternatively, you can use the perfmon command in the Command Prompt to open it. Add Counters: In Performance Monitor, click the "+" in the top-left corner to add counters. In the "Add Counters" window, select "Network" as the object type. In the "Instances" list, choose the network interface you want to monitor (e.g., Local Area Connection, Wireless Connection, etc.). In the "Counters" list, find and select "UDP Packets Received Errors (due to buffer overflow)". Click the "Add" button to add this counter. Repeat the above steps to add other interfaces you want to monitor. View the Results: In the main window of Performance Monitor, you should see a chart showing the number of UDP packets dropped due to a full receive buffer for each selected interface. You can click different parts of the chart to view detailed data for different time periods. Please note that this method provides real-time performance data, so it may not be suitable for viewing historical data. If you need to view historical data, you may need to use other tools or methods to collect and analyze these data. Additionally, make sure your system has the appropriate drivers and updates installed to correctly report these performance counters. If your system does not display the "UDP Packets Received Errors (due to buffer overflow)" counter, it may be because your drivers or system do not support this feature.
