Identifying critical metrics to monitor: disk capacity, I/O performance, log backup status, and volume health.

Establishing a robust monitoring framework is the cornerstone of any effective self-healing system for the SAP HANA /hana/log/ file system. Without precise, real-time insights into the log volume's health and performance, autonomous remediation becomes impossible. The initial step in constructing this intelligent monitoring layer involves identifying the critical metrics that provide an accurate and comprehensive picture of the system's state. These selected metrics serve as the primary inputs for our monitoring agents, triggering subsequent diagnostic and remediation workflows.

The foundational metric for any robust /hana/log/ self-healing system is undoubtedly disk capacity. As the transaction log continuously grows, consuming disk space, proactive monitoring of this resource is paramount. Running out of log volume space is a critical event that can halt all database operations, leading to significant downtime. Our system must track not just the current percentage of disk used, but also the total free space available.
