[0070]

[0071] The above is a node class of a doubly linked list. previous and next respectively record the pointers of the preceding and following nodes, object is used to record the aggregate object to be cached, and timestamp is used to record the timestamp when the current node was created. When the timestamp exceeds the life cycle of the node, it will be deleted by the remove() method. The main function of this class is to form a LinkedList linked list from LinkedListNode, and implement the basic methods of getFirst(), getLast(), addFirst(), addLast(), clear() and other linked lists by the LinkedList class.

[0072] This ensures that the aggregated objects are the latest data, and puts frequently accessed objects at the front of the linked list, which improves access efficiency.

[0073] 4. Database synchronization operation;

[0074] The purpose of using the cache in the embodiments of the present invention is to improve the concurrent access speed and the real-time...

Abstract

The invention provides a method and a device for data collection, which relate to the field of mass data processing and solve the problem of data lag caused by database storage. The method comprises the steps of: collecting data from nodes in cluster; and establishing aggregation in cache, using the collected data as the object of the aggregation and storing the data in the cache. The technical proposal provided by the invention is suitable for high performance cluster.

Description

technical field [0001] The invention relates to the field of mass data processing, in particular to a data collection method and device. Background technique [0002] The data volume of high-performance cluster monitoring is increasing, and at the same time, the requirements for monitoring performance are also getting higher and higher, so higher requirements are also put forward for cluster monitoring. At present, the mainstream cluster monitoring technology is to monitor data in real time. However, when the amount of data is large, data monitoring will cause a certain delay, which may cause the response time of the page to be too long, and then cause the page to freeze. The problem of unresponsive pages can be solved through database buffering, that is, the nodes put all the data in the database in a unified way, and the wen server takes out the data from the database in a unified way to form a page. Although this approach has greatly alleviated the phenomenon of suspende...
