Execution Related Issues

Q1: How to troubleshoot execution timeouts?

⚠️ Four Major Causes:

1. Process killed --> Resource cleanup failed
2. Thread overload --> CPU usage > 90%
3. Network congestion --> Sampling data delay
4. Configuration error --> Timeout threshold too low

🔍 Diagnostic Tools:

# Check system load  
top -H -p <Execution Process PID>  
  
# Verify sampling delay  
cat /opt/AngusTester/data/exec/ExecutionID/runner.log

Q2: How to resolve startup failures?

🚫 Three Failure Scenarios:

Failure Type	Symptoms	Solution
Node unavailable	"No available nodes found"	Restart execution agent service (AngusAgent)
Agent exception	"Connection refused"	Check firewall settings for ports
Script error	Configuration validation failed	Debug scripts and scenarios first

📍 Diagnostic Path:
Execution details page → Error logs → Check "Failure reason code"

Q3: How to monitor execution status in real time?

📊 Four-Dimensional Monitoring Dashboard:

1. Execution progress --> Percentage progress bar
2. Resource consumption --> CPU/Memory curves
3. Sampling quality --> Data points/5 seconds
4. Exception alerts --> Real-time pop-ups

🚨 Critical Thresholds:

• Memory usage > 80% → Automatic sampling rate reduction
• Progress stalled for 5 minutes → Pause execution

Q4: How to recover from a stuck execution?

🔄 Three-Level Recovery Mechanism:

1. Auto-resume: Automatically restarts after 30 seconds of no response
2. Manual intervention: Console → Execution monitoring → Force resume
3. Log diagnosis: Analyze control logs or export execution snapshots to examine thread stacks

💡 Preventive Measures:
Enable pre-check mode to verify resource availability in advance

Q5: How to improve execution stability?

🛡️ Five-Dimensional Reinforcement Plan:

Optimization Area	Configuration Suggestion
Resource isolation	Limit max threads per task
Timeout strategy	Set timeout to 2x sampling interval
Heartbeat check	Status reporting every 5 seconds
Resource reservation	Reserve 20% system resources
