Scenario: Your application's performance is degrading, and you suspect it's due to excessive logging. How would you use CloudWatch Logs to identify and mitigate this issue?
- Disable logging altogether
- Increase logging verbosity
- Manually review log files
- Set up log metric filters and alarms
By setting up log metric filters and alarms in CloudWatch Logs to extract specific patterns from log events related to performance degradation and alerting when these metrics exceed thresholds, you can identify and mitigate issues caused by excessive logging.
Scenario: You need to comply with regulatory requirements to retain log data for seven years. How would you configure CloudWatch Logs to meet this requirement effectively?
- Create retention policies
- Increase log group size
- Manually delete old log data
- Use CloudTrail instead
By creating retention policies in CloudWatch Logs, you can specify the retention period for log data, ensuring that it is retained for the required duration of seven years to comply with regulatory requirements.
