Event and Accounting Logs
Events that are suppressed by event control will not generate any event log entries. Event control
maintains a count of the number of events generated (logged) and dropped (suppressed) for each
application event. The severity of an application event can be configured in event control.
An event log within the 7210 SAS OS associates the event sources with logging destinations.
Examples of logging destinations include, the console session, a specific telnet or SSH session,
memory logs, file destinations, SNMP trap groups and syslog destinations. A log filter policy can
be associated with the event log to control which events will be logged in the event log based on
combinations of application, severity, event ID range, VRF ID, and the subject of the event.
The 7210 SAS accounting logs collect comprehensive accounting statistics to support a variety of
billing models. The routers collect accounting data on services and network ports on a per-service
class basis. In addition to gathering information critical for service billing, accounting records can
be analyzed to provide insight about customer service trends for potential service revenue
opportunities. Accounting statistics on network ports can be used to track link utilization and
network traffic pattern trends. This information is valuable for traffic engineering and capacity
planning within the network core.
Accounting statistics are collected according to the parameters defined within the context of an
accounting policy. Accounting policies are applied to customer Service Access Points (SAPs) and
network ports. Accounting statistics are collected by counters for individual service queues
defined on the customer's SAP or by the counters within forwarding class (FC) queues defined on
the network ports.
The type of record defined within the accounting policy determines where a policy is applied,
what statistics are collected and time interval at which to collect statistics.
The only supported destination for an accounting log is a compact flash system device (cf1: or
cf2:). Accounting data is stored within a standard directory structure on the device in compressed
XML format.
