Dell PowerVault ME5 Series Administrator's Guide

Administering a log-collection system

A log-collection system receives log data that is incrementally transferred from a storage system for which the managed logs feature is enabled, and is used to integrate the data for display and analysis. For information about the managed logs feature, see Managed logs. Over time, a log-collection system can receive many log files from one or more storage systems. The administrator organizes and stores these log files on the log-collection system. Then, if a storage system experiences a problem that needs analysis, that system's current log data can be collected and combined with the stored historical log data to provide a long-term view of the system's operation for analysis. The managed logs feature monitors the following controller-specific log files:

• Expander Controller (EC) log, which includes EC debug data, EC revisions, and PHY statistics
• Storage Controller (SC) debug log and controller event log
• SC crash logs, which include the SC boot log
• Management Controller (MC) log

Each log-file type also contains system-configuration information.
