How log files are transferred and identified

Log files can be transferred to the log-collection system in two ways, depending on whether the managed logs feature is configured to operate in push mode or pull mode.

• Push mode—when log data has accumulated to a significant size, the storage system sends notification events with attached log files through email to the log-collection system. The notification specifies the storage-system name, location, contact, and IP address, and contains a single log segment in a compressed .zip file. The log segment is uniquely named to indicate the log-file type, the date and time of creation, and the storage system. This information is also in the email subject line. The file name format is logtype_yyyy_mm_dd__hh_mm_ss.zip.
• Pull mode—when log data has accumulated to a significant size, the system sends notification events using email or SNMP traps to the log-collection system. The notification specifies the information that is transferred such as the storage-system name, location, contact, IP address, and the log-file type (region). The FTP or SFTP interface on the storage system can be used to transfer the appropriate logs to the log-collection system, as described in Transferring log data to a log-collection system.
