||
|
|
- Current: 800ms (4x baseline)
|
||
|
|
- Threshold: 500ms
|
||
|
|
- Status: Degradation detected
|
||
|
|
- **System Response:** Alert generated and escalated
|
||
|
|
|
||
|

||
|
|
- User impact: Moderate (slower response times)
|
||
|
|
- Service impact: Degraded performance
|
||
|
|
- Business impact: Minimal (service still functional)
|
||
|
|
- Root cause: Unknown (requires investigation)
|
||
|
|
|
||

|
|
5. Identify bottlenecks
|
||
|
|
- **Findings:**
|
||
|
|
- Database query performance: Degraded
|
||
|
|
- Query execution time: Increased 5x
|
||
|
|
- Database connections: High utilization (95%)
|
||
|
|
- Root cause: Database connection pool exhaustion
|
||
|
|
|
||
|
|
### 3.2 Performance Optimization
|
||
|
|
- **Time:** 14:20 UTC
|
||
|
|
- **Optimization Actions:**
|
||
|
|
1. Increase database connection pool
|
||
|
|
2. Optimize slow queries
|
||
|
|
3. Add database indexes
|
||
|
|
4. Adjust connection timeout
|
||
|
|
- **Optimization Status:**
|
||
|
|

|
||
|
|
- Queries: Optimized
|
||
|
|
- Indexes: Added
|
||
|
|
- Timeout: Adjusted
