The autosupport daemon monitors the storage system's operations and sends automatic messages to technical support to alert it to potential system problems. If necessary, technical support contacts you at the e-mail address that you specify to help resolve a potential system problem.
AutoSupport is enabled by default when you configure your storage system for the first time. After a grace period of 24 hours, AutoSupport messages start being generated. You can disable AutoSupport at any time using the autosupport.enable option, but you are strongly advised to leave it enabled. Enabling AutoSupport can significantly speed problem determination and resolution should a problem occur on your storage system.
Two AutoSupport messages are generated at this time. One, the weekly AutoSupport message, provides the same system information as regular AutoSupport messages. The other, the performance AutoSupport message, provides technical support with comprehensive performance information about your storage system for the preceding week. The performance message can be quite large, so by default it is sent only to technical support.
