Visualize and Report Log Data

Understanding your log data at scale requires more than raw messages—it requires visual insights that help teams track performance, detect anomalies, and report on activity across the organization. Graylog provides robust visualization and reporting tools that turn complex data into actionable intelligence.

This section of the documentation introduces the features that support data visualization and reporting in Graylog, including dashboards, widgets, and report generation. These tools allow users to track metrics, monitor system behavior, and share key insights with stakeholders in real time or on a scheduled basis.

Dashboards

Dashboards in Graylog are customizable interfaces for visualizing log data in real time. Each dashboard consists of one or more widgets that present data in graphical or tabular form, making it easier to interpret log activity, security events, performance trends, and more.

Dashboards can be configured to display data from specific streams, queries, or timeframes, and are frequently used to monitor infrastructure health, application logs, or security metrics. You can create multiple dashboards for different teams or use cases, and share them across your organization to support visibility and collaboration.

Widgets

Widgets are the building blocks of dashboards. Each widget represents a specific visualization—such as a line chart, pie chart, bar graph, data table, or single value—that is based on a saved search or dynamic query.

Widgets are highly customizable and support filtering, aggregation, and transformation of log data. You can use them to chart message volume, highlight top sources of error logs, or display unique counts of logins per user or location.

Reporting

Graylog’s reporting feature allows you to generate and distribute visual summaries of your log data. Reports are based on saved dashboards and can be scheduled to run at regular intervals, producing downloadable PDF documents for compliance, audits, or executive visibility.

Reports are ideal for tracking long-term trends, summarizing key metrics, or sharing security posture updates with stakeholders outside of the Graylog interface. You can include multiple dashboard views in a single report and configure access control to restrict who can view or generate reports.
