Historically the most common transport layer protocol for network logging has been User Datagram Protocol (UDP), with the server listening on port 514. In this article we will use DD-WRT as an example. parameter of openlog() is not available When the Log Analytics agent for Linux is installed, it configures the local Syslog … Clients send data to the server over UDP on port 514, with TCP options also available.
