Abstract

The present application provides a metadata performance monitoring method. The method comprises: writing values in target metadata into a shared memory; acquiring a value corresponding to performance monitoring from the shared memory; and determining whether the value is in a present threshold range, and if no, carrying out performance tuning. According to the method provided by the present application, the shared memory is used to replace an originally used log analysis method and piling analysis method. Statistic data of associated performance of the metadata is acquired by virtue of the shared memory, so that influences on the metadata performance are reduced, debugging is convenient and flexible, and metadata performance monitoring accuracy is improved.

Description

technical field [0001] The present application relates to the field of distributed file systems, in particular to a metadata performance monitoring method and system. Background technique [0002] With the development of technology, people pay more and more attention to metadata performance monitoring. [0003] Currently, the most widely used metadata performance tuning methods are the log tuning method and piling tuning method. The log tuning method first identifies the functions on the critical path, and then adds logs to the key functions to obtain the required tuning information, such as the number of function calls, the time of function calls, the number of variable usage, etc., but using the log Debugging is faced with many problems, such as selecting the location to add logs, adding too many logs, etc., which are not easy to deal with; the piling method is to add some hook functions or callback functions inside the function, which will affect performance.
