What is Syslog?
Syslog is a message logging protocol that allows devices and applications to send information relating to things such as status, events and diagnostics. Each syslog message carries a severity level, which ranges from 0 (the highest severity, indicating an emergency) to 7 (the lowest, indicating a debugging message). Syslog events triggered by one router can differ greatly than those triggered by another, making managing messages difficult.
Devices and applications send messages to syslog servers, which collect, manage and interpret them before issuing alerts and notifications. These servers can be software, embedded virtual machines (VMs) and even hardware appliances. Syslog servers often accept SNMP (Simple Network Management Protocol) data, too.
Syslog sends messages through the User Data Protocol (UDP) on port numbers 514 and 601.
