Abstract
A system and method is disclosed for preventing the loss of event messages due to message buffer overruns. A fixed vendor-specific buffer pool is loaded with log messages by firmware in an adapter. A service application periodically polls a device driver for messages in the buffer pool. The device driver responds with the number of messages stored in the buffer pool and the total number of buffers in the buffer pool. The service application then issues 'get next message' requests to receive the stored messages. Once the buffer pool has been emptied, the service application writes the messages to a disk file. The service application then computes a percent utilization of the buffer pool, and if the percent utilization exceeds a predetermined threshold, an algorithm is employed for increasing the polling frequency. If the percent utilization is below the threshold, an algorithm is employed for decreasing the polling frequency.
