System Monitoring

The security appliance can generate system and debug messages when an event occurs. These messages can be logged to the local buffer or to an external server, depending on an organization’s security policies. This section discusses how to enable event logging and Simple Network Management Protocol (SNMP) polling, which can be used to check the status of the security appliance. This section also discusses how to monitor the health of the security appliance by monitoring the CPU and memory utilization.

System Logging

System logging is a process by which the Cisco ASA generates an event for any significant occurrence that affects the system, such as network problems, error conditions, and threshold breaches. These messages can either be stored locally on the system buffer or be transferred to external servers. You can use these logs for event correlations to detect network anomalies or you can use them for monitoring and troubleshooting purposes.
