Optimize packet captures

- [Instructor] Wireshark is software…that's a packet sniffer and analysis tool.…Because Wireshark has a rich graphical interface,…it may need additional processing…that might use CPU and GPU as well as memory over time.…This can lead to memory errors…and system performance issues.…Using Wireshark to capture packets…may have an unexpected drain on your system resources.…Wireshark and several other software packet analysis tools…are free and work with most operating systems.…

However, there are also some commercial sniffer products…that are more robust.…In addition, there are dedicated appliances…that are designed for optimal capture capture…and minimal packet loss.…Some things you can do to optimize packet capture…is when capturing during troubleshooting…or while baselining, quit any unnecessary programs.…You could also use a ring buffer…if you're simply monitoring for a certain type of traffic…but to really optimize packet capture,…you can use a command line interface tool.…

In Unix or Unix-like operating systems…
