What is a common approach for setting up alerts based on logs?

Sending an alert for every log entry

Defining a threshold for the number of ERROR-level log entries within a time window

Alerting when log files are rotated

Only alerting when the application crashes

A company's log management platform is running out of storage. The compliance team requires logs to be kept for 1 year, but the operations team needs fast access to logs from the last 7 days for troubleshooting. The current setup stores all logs in hot storage. Which change should they make?

Reduce the retention period to 30 days to free up storage space.

Delete all logs older than 7 days and rely on backups of the application database.

Move logs older than 7 days to a cheaper cold storage tier, while keeping the last 7 days in hot storage.

Compress logs in hot storage to save space without changing the storage tier.

Why is it important to include a request ID or transaction ID in application logs?

To identify the user who generated the log entry

To correlate log entries from different services that handle the same request

To encrypt the log entry for security

To reduce the size of log entries

What is the purpose of a log retention policy?

To ensure logs are deleted as soon as they are read

To define how long logs are kept and when they are archived or deleted

To increase the verbosity of log messages

A developer is adding logging to a new feature. The feature has a code path that handles expected user input validation failures and another path that handles unexpected exceptions. The developer wants to log these appropriately. Which combination of log levels should they use?

Use ERROR for both validation failures and unexpected exceptions.

Use WARN for validation failures and ERROR for unexpected exceptions.

Use INFO for validation failures and DEBUG for unexpected exceptions.

Use DEBUG for validation failures and INFO for unexpected exceptions.
