Logs

Records of events emitted by an application or system, often with timestamps and contextual fields.

An example you can picture

An API logs a failed database request with a timestamp, severity, and request identifier. That identifier helps connect the event to other records from the same request.

The distinction that matters

More logs are not automatically more useful. Avoid sensitive data, choose useful fields, and manage retention and access.

Put it into practice

Create a harmless application error in a local lab. Find its log record and identify the timestamp, severity, and useful context. Remove secrets or personal data before sharing the record.

Connect the ideas: trace and observability. For the bigger picture, read the related learning guide.
