# Segments Segments are saved filters on [Log](https://docs.dbnl.com/v0.27.x/workflow/logs) data corresponding to a specific behavioral signal discovered manually or from an [Insight](https://docs.dbnl.com/v0.27.x/workflow/insights). All Segments are computed and published to the [Segments Dashboard](https://docs.dbnl.com/v0.27.x/dashboards#segments-dashboard) as part of the [DBNL Data Pipeline](https://docs.dbnl.com/v0.27.x/configuration/data-pipeline) and adapt future analytics by informing DBNL that the saved Segment is a meaningful bifurcation of the [Logs](https://docs.dbnl.com/v0.27.x/workflow/logs) data. ## When to Create Segments Create a segment when you've identified a meaningful behavioral pattern you want to track over time, such as: * **Error conditions**: Logs containing specific error types or failure patterns * **High-value interactions**: User sessions with purchases, conversions, or key actions * **Quality issues**: Low-scoring responses that need monitoring * **User cohorts**: Specific user groups (power users, new users, etc.) * **Performance bottlenecks**: Requests exceeding latency thresholds Once saved, segments are automatically analyzed in future pipeline runs, generating dedicated metrics and appearing on dashboards. ## Creating Segments Segments can be created in three ways: 1. From an [Insight](https://docs.dbnl.com/v0.27.x/workflow/insights) that specifies a Segment corresponding to the behavioral signal observed 2. Anywhere a filter is constructed on the [Explorer](https://docs.dbnl.com/v0.27.x/workflow/explorer) or [Logs](https://docs.dbnl.com/v0.27.x/workflow/logs) pages 3. Manually from the Segments page on the sidebar Segments can be modified or deleted from the Segments page on the sidebar.
