ABSTRACT:
One embodiment of the present invention provides a system that dynamically adjusts data resolution during proactive-fault-monitoring in a computer system. During operation, the system temporarily stores high-resolution data for a telemetry signal from the computer system in a buffer. The system then generates low-resolution data for the telemetry signal from the high-resolution data. Next, the system monitors the low-resolution data, and while doing so, determines if an anomaly exists in the low-resolution data. If an anomaly exists in the low-resolution data, the system records the high-resolution data from the buffer on a storage device.
