The invention provides a log-management optimizing method for a clustered storage system, wherein the method comprises the following steps of: carrying out centralized management and analysis by sending the log of each node onto a log server by adopting two real-time modes, storing a log file according to an analyzing result, establishing a compressed strategy, establishing a log-index table for the logs by utilizing a database, and finally showing the log-inquiring result of each module to a user through a log-viewing strategy; and the method comprises a log-centralizing strategy module, a log-analyzing strategy module, a log-storing strategy module and a log-displaying strategy module, the method is used for carrying out centralization, analysis and collection and optimizing log storage for the logs dispersed at each clustered node, the mistaken log information of the clustered storage system can be rapidly positioned by a system manager by providing the log-viewing strategy, the useful log information is clearly obtained, the integral operating condition of each application module is known, the log record of the system is effectively tracked in time, and the safety of the system is guaranteed.
