Logs often take up the majority of a company's data assets. Examples of logs include business logs (such as user activity logs) and Operation and Maintenance logs of servers, databases, and network or IoT devices.
Logs are the guardian angel of business. On the one hand, they provide system risk alerts and help engineers quickly locate root causes in troubleshooting. On the other hand, if you zoom them out by time range, you might identify some helpful trends and patterns, not to mention that business logs are the cornerstone of user insights.
