Step 4 - UDP Logs OverviewCopy

UDP (or User Datagram Protocol) is a communication transport protocol used across the Internet for a range of transmission types, including video playback or DNS lookups.

As this protocol doesn’t require a “handshake”, it makes data transfer a lot faster but also creates a gateway that could be easily exploited.

Because of the lack of handshake, there are no guarantees that your data will be delivered successfully and won’t be duplicated. Users that require error correction facilities may prefer to use TCP instead of UDP to remedy the concerns cited above.

Where error checking isn’t a vital concern UDP is the preferred protocol when time is of the essence for your data transfers. It is often used across the following use cases: live broadcasts, video chats & multiplayer games.

Our UDP log file analyser can be used to view, manage and centralise your log messages as well as deliver metrics for detailed and dynamically updating Kibana visualisations.

If you need any assistance with analysing your UDP log data we're here to help. Feel free to reach out by contacting the Logit support team via live chat & we'll be happy to help you start analysing your data.
