+Objective:
+To assess and ensure the optimal performance of the PostgreSQL database by reviewing key metrics, logs, and slow queries.
+
+Step 1:
+Check CPU Utilization:
+
+Retrieve and analyze the CPU utilization metrics.
+Ensure CPU usage is within acceptable limits (e.g., below 60%).
+
+Step 2:
+Review Other Key Metrics:
+
+Freeable Memory: Ensure sufficient memory is available (e.g., above 20 GB).
+Database Connections: Monitor for spikes; ensure connections are within expected limits.
+Read/Write IOPS: Check for any unusual spikes or bottlenecks.
+Disk Queue Depth: Ensure it remains at 0 to avoid I/O bottlenecks.
+
+Step 3:
+Analyze Logs:
+
+Retrieve recent logs and look for warnings or errors.
+
+Step 4:
+Evaluate Slow Queries:
+
+Retrieve and review slow queries.
+Identify known queries and ensure they are optimized or deemed acceptable.
+
+Step 5:
+Document Findings:
+
+Record any issues found and actions taken.
+Note any recurring patterns or areas for improvement.
