# Technical Analysis of Network Performance Metrics
## Graph 1: Alarm KPI
- **Y-Axis**: Ranges from 0.0 to 1.0 (unitless)
- **X-Axis**: Time intervals from 00:49 to 01:59
- **Legend**:
- **Yellow**: Packet Loss
- **Pink**: Network Interrupt
- **Key Observations**:
- Two **Packet Loss** events (yellow shading) occur at:
- 01:19 (sharp dip in Alarm KPI)
- 01:29 (moderate dip in Alarm KPI)
- One **Network Interrupt** event (pink shading) occurs at:
- 01:49 (severe drop in Alarm KPI, reaching ~0.2 before recovery)
## Graph 2: RC by KPIRoot+ (Root Cause)
- **Y-Axis**: Ranges from 0.0 to 1.0 (unitless)
- **X-Axis**: Time intervals from 00:49 to 01:59
- **Key Observations**:
- Correlates with **Packet Loss** events:
- 01:19: Sharp dip in RC by KPIRoot+ (~0.6)
- 01:29: Moderate dip in RC by KPIRoot+ (~0.4)
- Correlates with **Network Interrupt** event:
- 01:49: Severe drop in RC by KPIRoot+ (~0.2) followed by recovery
## Graph 3: RC by KPIRoot
- **Y-Axis**: Ranges from 0.0 to 1.0 (unitless)
- **X-Axis**: Time intervals from 00:49 to 01:59
- **Key Observations**:
- Correlates with **Packet Loss** events:
- 01:19: Sharp dip in RC by KPIRoot (~0.6)
- 01:29: Moderate dip in RC by KPIRoot (~0.4)
- Correlates with **Network Interrupt** event:
- 01:49: Severe drop in RC by KPIRoot (~0.2) followed by recovery
## Cross-Graph Analysis
1. **Packet Loss Events**:
- Both **RC by KPIRoot+** and **RC by KPIRoot** show proportional dips during yellow-shaded intervals.
- **Alarm KPI** also declines during these periods, suggesting a direct relationship between packet loss and system performance degradation.
2. **Network Interrupt Event**:
- All three metrics experience the most severe drops during the pink-shaded interval (01:49).
- **RC by KPIRoot+** and **RC by KPIRoot** recover faster than **Alarm KPI**, which remains suppressed until ~01:55.
3. **Temporal Patterns**:
- **Packet Loss** events are shorter in duration (~5 minutes) compared to the **Network Interrupt** (~10 minutes).
- **RC by KPIRoot+** exhibits more volatility than **RC by KPIRoot**, indicating potential differences in root cause attribution methodologies.
## Recommendations
- Investigate root causes of **Packet Loss** events (01:19, 01:29) to prevent recurring performance issues.
- Prioritize mitigation strategies for **Network Interrupt** events (01:49) due to their prolonged impact on system stability.
- Validate correlation between **RC by KPIRoot+** and **RC by KPIRoot** to standardize root cause analysis frameworks.
