1.(optional, advanced) Develop an observability tool that provides metrics for synchronous versus asynchronous file system writes. This should include their rate and latency and be able to identify the process ID that issued them, making it suitable for workload characterization. 2. (optional, advanced) Develop a tool to provide statistics for indirect and inflated file system I/O: additional bytes and I/O not issued directly by applications. The tool should break down this additional I/O into different types to explain their reason. 1. What are IOPS?
