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.

  • Set up local logging in the Log Configuration section.

  • 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.

Severity Level Description
EMERGENCY System is unusable.
ALERT Includes all alarms the appliance generates: CRITICAL, MAJOR, MINOR, and WARNING.
CRITICAL 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 Support for debugging.
NONE If you select NONE, no events are logged.
  • The bolded part of the name is what displays in the log files.

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

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

Configure Remote Logging

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

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

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

  • 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.
