METHOD FOR OBTAINING LOG INFORMATION FROM NETWORK ELEMENT DEVICE BY NETWORK MANAGEMENT SERVER, A NETWORK ELEMENT DEVICE AND A NETWORK MANAGEMENT SERVER

摘要

A method for the network management server to get the log information from the network element device comprises: firstly, the network element device allocates a section of the memory resource as the log buffer, and stores the log information generated by the network element device in the log buffer; then, the network element device detects dynamically the residual capacity of the log buffer, and when the residual capacity of the log buffer is less than the special threshold, it notifies the network management server to fetch the log information. The present invention can avoid the loss of the log information of network element device to ensure the categoricalness of the log information.
