Chapter 11 Maintaining and Managing the SN 5428-2 Storage Router
Using the SN 5428-2 Logging Facilities
Messages are routed by creating a list of routing rules that is searched for a facility and notification level
match whenever an event or debug message is received. This list of routing rules is known as the storage
router logging table.
By default, the logging table includes rules to log all messages at notification level notice (or numerically
lower levels) to all destinations, and to log all messages at notification level info to the storage router
log file. Any message that does not find a matching rule is not logged to any destination.
Use the show logging command to display the current logging table routing rules and other logging
information.
Filtering and Routing Event Messages
The logging table allows messages to be filtered by their facility and notification level and routed to the
specified destination(s). When an event message arrives, the logging table rules are searched by facility
name and by level until the first match is found. The message is sent to all the destinations specified by
the matching rule. If no match is found, the event message is discarded.
When a new routing rule is added, it is appended to the existing table. Use the logging level command
to add a new routing rule to the logging table; use the logging #? command to insert a routing rule into
the logging table before the specified entry.
Each facility can have eight notification levels. Each facility and notification level pair can have up to
seven destinations.
In Example 11-11, the facility is SNMP, and the notification level is 5 (notice). If the logging table
included the entries in Example 11-12, the event message in Example 11-11 would match on the first
routing rule, and would be sent to all valid destinations. Any message from the SNMP facility at
notification level info, and any message from another facility at notification level info (or lower) would
match on the second rule and be sent to the storage router console and log file. All messages from any
facility at notification level debug would be discarded.
