While monitoring a Spring Boot application, you observe a sudden spike in response times. How would you determine whether the issue is related to the application code, database interactions, or external service calls, and what steps would you take to address it?
- Examine application logs and metrics to pinpoint the source of the issue.
- Restart the application server to clear caches.
- Add more replicas to the database for load balancing.
- Increase the network bandwidth between the application and the database.
Option 1 is correct. Monitoring logs and metrics can help identify if the spike in response times is caused by application code, database queries, or external service calls. Restarting the server or adding database replicas/network bandwidth may temporarily alleviate the issue but won't provide insights into the root cause. Addressing the root cause might involve optimizing code, database queries, or addressing external service bottlenecks, depending on the identified source.
