Embodiments described herein are generally directed to a software CE counter and leaky bucket for PCIe and CXL devices. In an example, when a burst of CEs exceeding an error threshold is reported by a PCIe or CXL device associated with a computer system, CE reporting for the device is disabled and a notification is issued to the BMC. Responsive to receipt of the notification, the BMC performs threshold-based error rate monitoring. An error counter is decremented by the BMC in accordance with a leak rate of a leaky bucket implemented by the BMC for the device. During periodic error monitoring performed by the BMC for new CEs logged by the device, the error counter is incremented when a new correctable error has been logged by the device since a prior error monitoring interval. Based on the error counter, the BMC distinguishes between persistent and temporal errors of the device.
