Overview
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
You can configure the messages that are written to each log by severity, and
amessage can go to more
Log Management
You can enable or disable logging on the Log Management page
You can select the events by severity level Each log message has a severity
level marked with the first letter of the severity level separated by dashes
(-) 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
•
Error—System is in error condition
•
Warning—System warning has occurred
•
Notice—System is functioning properly, but a system notice has occurred
•
Informational—Device information
•
Debug—Detailed information about an event
You can select different severity levels for RAM and Flash logs These logs are
displayed in the RAM Log page and Flash Memory Log page, respectively
Selecting a severity level to be stored in a log causes all of the higher severity
events to be automatically stored in the log Lower severity events are not
stored in the log
For example, if Warning is selected, all severity levels that are Warning and
higher are stored in the log (Emergency, Alert, Critical, Error, and Warning) No
events with severity level below Warning are stored (Notice, Informational,
and Debug)
