Which protocol utilizes UDP port 514 for collecting events?

The protocol that utilizes UDP port 514 for collecting events is Syslog. Syslog is a standard for message logging that allows network devices and servers to send event notification messages to a logging server. The use of UDP makes it a lightweight option for collecting logs and events from various devices across the network without the overhead associated with connection-oriented protocols.

Syslog is particularly known for its ability to handle logging from a variety of sources, including firewalls, routers, and servers, which all send their log information to a centralized Syslog server using this port. The simplicity and efficiency of Syslog, combined with its widespread adoption in network management, make it an essential tool for system administrators in monitoring and troubleshooting environments.
