Chapter 1 Introduction to System Messages for the Cisco MDS 9000 Family Capturing System Messages and History Send documentation comments to [email protected] Fabric Manager Configuration Guide). Only system messages that correspond to the configured logging level or higher severity messages are logged. As an example, if you set the logging level to 3 (error), then you get error, critical, alerts, and emergency system messages, but you do not get warning, notification, informational, or debugging system messages. Saving the System Messages Log The logging logfile global configuration command enables copying of system messages to an internal log file and optionally sets the size of the file. To display the messages that are logged in the file, use the show logging EXEC command. The first message displayed is the oldest message in the buffer. To clear the current contents of the buffer, use the clear debug-logfile privileged EXEC command. Logging System Messages to a Syslog Server The logging host-name command identifies a syslog server host to receive logging messages. The host-name argument is the name or Internet address of the host. By issuing this command more than once, you build a list of syslog servers that receive logging messages. The no logging host-name command deletes the syslog server with the specified address from the list of syslog servers. OL-15956-01 Cisco MDS 9000 Family System Messages Reference 1-5
