Abstract :
We present a high performance logging system for embedded UNIX and GNU/Linux applications. Compared to the standard UNIX and GNU/Linux logging method, syslog, our method has two orders of magnitude lower latency and an order of magnitude higher message throughput. This speed-up is mainly due to the use of a memory-mapped file as the means of inter-process communication, fewer memory copies and the batching of output messages in the logging daemon. In addition, our logging system also accepts syslog messages, providing compatibility with existing applications. Our logging system is in production use in the Cisco UCS Virtual Interface Card.
