Zusammenfassung:A method and system for generating a web log that includes transaction entries from transaction queues of one or more cores of a multi-core system. A transaction queue is maintained for each core so that either a packet engine or web logging client executing on the core can write transaction entries to the transaction queue. In some embodiments, a timestamp value obtained from a synchronized timcstamp variable can be assigned to the transaction entries. When a new transaction entry is added to the transaction queue, the earliest transaction entry is removed from the transaction queue and added to a heap. Periodically the earliest entry in the heap is removed from the heap and written to a web log. When an entry is removed from the heap, the earliest entry in a transaction queue corresponding to the removed entry is removed from the transaction queue and added to the heap.
