If Correlation IDs are missing from logs in some microservices, what is the most probable cause?
medium📝 Analysis Q6 of 15
Step-by-Step Solution
Solution:
Step 1: Understand propagation of Correlation IDs
Correlation IDs must be passed explicitly in request headers between services.Step 2: Identify cause of missing IDs
If logs lack Correlation IDs, it usually means the ID was not forwarded or extracted properly.Step 3: Eliminate other options
Different languages do not inherently cause missing IDs; logging frameworks can be configured; encryption does not prevent logging if handled correctly.Final Answer:
The Correlation ID was not propagated correctly in the request headers -> Option AQuick Check:
Missing IDs usually mean propagation failure [OK]
Quick Trick: Missing Correlation IDs usually mean header propagation failed [OK]
Common Mistakes:
MISTAKES- Blaming programming language differences
- Assuming logging framework lacks support
- Thinking encryption prevents logging
