QUICK HEALTH CHECK:
|
|
================================================================================
|
|
|
|
To view critical issues check diagnostics file for:
|
|
* Section 5: TABLES WITH HIGH SEQUENTIAL SCANS
|
|
* Section 8: UNUSED OR RARELY USED INDEXES
|
|
* Section 10: SLOWEST QUERIES
|
|
|
|
To identify slow queries check query_analysis file for:
|
|
* Section 2: TOP 20 SLOWEST QUERIES (by max execution time)
|
|
* Section 5: BASEITEMS TABLE QUERIES ANALYSIS
|
|
|
|
================================================================================
|
|
RECOMMENDED ACTIONS:
|
|
================================================================================
|
|
|
|
* Review slow queries taking longer than 10 seconds
|
|
* Check if new indexes are being utilized
|
|
* Look for tables with many sequential scans
|
|
* Monitor cache hit ratio (should be above 95 percent)
|
|
* Check for tables with high dead tuples percentage (need VACUUM)
|
