Monitor
The monitor is the current telnet or SSH session. Events are seen in real-time, and only by the telnet or SSH session
(monitor) that requested them.
Local Log (Volatile and Non-Volatile)
The volatile local log stores messages only in the DOCSIS® cable device MIB (docsDevEvent) and is only accessible via
SNMP.
Syslog Server
A Syslog server is a networked device that receives and logs system messages from other networked devices. The C4/c
CMTS can be configured to send system event messages to the IP address, and port of a Syslog server.
SNMP Management Station
The Simple Network Management Protocol Management (SNMP) station is an application that uses the SNMP protocol to
manage a device or node.
SNMP is a User Datagram Protocol (UDP) based network protocol that is used to monitor network devices for conditions
that require the attention of an administrator.
Event Message Routing
Event messages are routed according to their priority values. They are logged and subsequently used during system
maintenance or network troubleshooting activities. All events carrying a routable priority are also stored in the volatile
logging history buffer.
