摘要:
Methods and apparatus for enhancing logging using non-volatile system memory are described. A computer system includes a system memory coupled to one or more processors. The system memory comprises at least a non-volatile portion. A range of memory locations within the non-volatile portion is selected as a low-latency high-durability log staging area. A plurality of log records representing respective events detected by one or more executable programs are generated, and at least a subset of the records is stored in the log persistence area. For analysis subsequent to a failure that results in a loss of data stored in a volatile portion of the system memory, log records written to the staging area within a time window immediately prior to the failure event are provided.
