Overview

Schema management offers a unified approach to governing your logs—letting you both discover the structure of ingested data and enforce the fields that matter most.

The Schema Explorer gives you full visibility into how your fields are structured and behave across your data. It surfaces vital insights like field paths, data types (including type collisions), usage patterns, cardinality trends, and mapping exceptions, helping you spot inconsistencies before they cause issues.

Reserved Fields moves from observation to action. You can explicitly define which fields must always be available for querying—pre-mapping them on ingestion with a specific data type to avoid index limits, misclassification, or query breakage. Reserved Fields ensure the critical parts of your schema remain consistent and performant.

Together, these tools provide a powerful 1-2 punch for schema hygiene: explore existing schema health, then reserve what’s essential. Want to keep queries reliable and your observability costs in check? Start with the Schema Explorer, then use Reserved Fields to solidify the parts of your schema that power your dashboards and alerts.
