Logging Template

Use this template to configure local and remote logging parameters.

Each requires that you specify the minimum severity level of event to log.

n	Set up local logging in the Log Configuration section.

n	Set up remote logging by using the Log Facilities Configuration and Remote Log Receivers sections.

Minimum Severity Levels

In decreasing order of severity, the levels are as follows.

EMERGENCY	The system is unusable.
ALERT	Includes all alarms the appliance generates: CRITICAL, MAJOR, MINOR, and WARNING
CRITICAL	A critical event
ERROR	An error. This is a non-urgent failure.
WARNING	A warning condition. Indicates an error will occur if action is not taken.
NOTICE	A normal, but significant, condition. No immediate action required.
INFORMATIONAL	Informational. Used by Silver Peak for debugging.
DEBUG	Used by Silver Peak for debugging
NONE	If you select NONE, then no events are logged.

n	The bolded part of the name is what displays in Silver Peak's logs.

n	If you select NOTICE (the default), then the log records any event with a severity of NOTICE, WARNING, ERROR, CRITICAL, ALERT, and EMERGENCY.

n	These are purely related to event logging levels, not alarm severities, even though some naming conventions overlap. Events and alarms have different sources. Alarms, once they clear, list as the ALERT level in the Event Log.

Configuring Remote Logging

n	You can configure the appliance to forward all events, at and above a specified severity, to a remote syslog server.

n	A syslog server is independently configured for the minimum severity level that it will accept. Without reconfiguring, it may not accept as low a severity level as you are forwarding to it.

n	In the Log Facilities Configuration section, assign each message/event type (System / Audit / Flow) to a syslog facility level (local0 to local7).

n	For each remote syslog server that you add to receive the events, specify the receiver's IP address, along with the messages' minimum severity level and facility level.
