Chapter 4: Administration: System Log; Setting System Log Settings - Cisco Small Business 200 Series Administration Manual

Administration: System Log
This section describes the system logging, which enables the device to generate multiple independent
logs. Each log is a set of messages describing system events.
The device generates the following local logs:
• Log sent to the console interface.
• Log written into a cyclical list of logged events in the RAM and erased when the device reboots.
• Log written to a cyclical log-file saved to the Flash memory and persists across reboots.
In addition, you can send messages to remote SYSLOG servers in the form of SNMP traps and SYSLOG
messages.
This section covers the following sections:
•

Setting System Log Settings

• Setting Remote Logging Settings
• Viewing Memory Logs
Setting System Log Settings
You can select the events to be logged by severity level. Each log message has a severity level marked
with the first letter of the severity level concatenated with a dash (-) on each side (except for Emergency
that is indicated by the letter F). For example, the log message "%INIT-I-InitCompleted: ... " has a severity
level of I, meaning Informational.
The event severity levels are listed from the highest severity to the lowest severity, as follows:
• Emergency—System is not usable.
• Alert—Action is needed.
• Critical—System is in a critical condition.
