Additional considerations

Syslogd on z/OS® receives remote messages as UDP packets on port 514. Because UDP is a connectionless protocol that does not provide reliable communications, the potential exists that some UDP packets containing forwarded syslogd messages can be dropped, either in the network as a result of network congestion or on the z/OS system if the syslogd is overloaded and cannot process incoming messages fast enough. If this occurs, these messages are not seen by the z/OS syslogd instance, nor is the remote syslogd instance made aware of the dropped messages. As a result, make provisions to enable direct access of syslogd messages on the remote hosts. In addition, you should perform a detailed evaluation on the risks associated with the potential for message loss, prior to using any z/OS-based automated operations software to trigger actions based on the remote messages received by the z/OS syslogd.
