Understanding message logging

The storage system maintains messages in the /etc/messages file on its root volume. The level of information that the storage system records in the /etc/messages file is configurable in the /etc/syslog.conf file.

You can access the /etc/messages file using your NFS or CIFS client, or using HTTP(S).
Note: You should check the /etc/messages file once a day for important messages. You can automate the checking of this file by creating a script on the administration host that periodically searches /etc/messages and then alerts you about important events.

Every Sunday at midnight, the /etc/messages file is copied to /etc/messages.0, the /etc/messages.0 file is copied to /etc/messages.1, and so on. The system saves messages for up to six weeks; therefore, you can have up to seven message files (/etc/messages.0 through /etc/messages.5 and the current /etc/messages file).

Message logging is done by a syslogd daemon. The /etc/syslog.conf configuration file on the storage system’s root volume determines how system messages are logged. Depending on their severity and origin, messages can be sent to the following entities:

By default, all system messages (except those with debug-level severity) are sent to the console and logged in the /etc/messages file. The messages include the storage system name.
