Grafana 6.4 introduces a new feature called the logs panel, designed to enhance data visualization by integrating log data with other visualized metrics on dashboards. This feature is particularly beneficial for system administrators and developers who regularly review logs to understand infrastructure behavior. The logs panel allows users to view correlations between visualized data and logs in real-time, enabling more efficient troubleshooting and monitoring. Setting up a logs panel involves duplicating an existing panel, modifying it to display logs by changing the datasource and query, and customizing the visualization to suit specific needs. Users can filter logs based on various criteria and add annotations for better insights into system behavior. This integration helps in identifying and resolving issues like internal server errors more effectively. For further guidance on using the logs panel, Grafana Labs provides documentation and video tutorials.
