> ## Overview of the C Series Controller Log Server

> The C Series Controller includes a system log server that you can configure to manage messages generated on the system. These messages record events that occur to system processes and components.

> You can configure the system log server on a C Series Controller to send messages about events to:

> - A local file
> - Other hosts that are running a system log server
> - Users who need to be notified about particular error conditions

> You configure which groups of messages are to be forwarded by message type and severity level.

> ## Message Groups

> Message groups (also called facilities) define sets of messages generated by the same software process or concerned with a similar condition or activity (such as authentication attempts).

> You can configure the following message groups for the system log server:

> - any—Messages from all facilities.
> - authorization—Authentication and authorization attempts.
> - daemon—Actions performed or errors encountered by various system processes.
> - ftp—Actions performed or errors encountered by an FTP process.
> - kernel—Actions performed or errors encountered by the kernel.
> - user—Actions performed or errors encountered by various user processes.
> - local7—Actions performed or errors encountered by different processes.

> ## Severity Levels

> You can specify the following severity levels for groups of messages to be forwarded:

> - any—Messages for all severity levels.
> - emergency—System panic or other condition that causes the system to stop functioning.
> - alert—Conditions that require immediate correction.
> - critical—Critical conditions, such as hard drive errors.
> - error—Error conditions that generally have less serious consequences than errors in the emergency, alert, and critical levels.
> - warning— Conditions that warrant monitoring.
> - notice—Conditions that are not errors but might warrant special handling.
> - info—Events or nonerror conditions of interest.
> - none—Messages are not generated for any condition.
