Stream Details

After data ingestion is complete, you can view detailed information about a stream using the Stream Details panel. This guide explains how to access the Stream Details panel and the information available in the panel.

Access

From the Streams page, select the Explore icon from the Actions column.

This opens the Stream Details panel, which provides configuration details, schema settings, and extended retention options.

Permission

User roles that have permission to update Streams can modify the stream settings from the Stream Details page. The permission needs to be assigned to appropriate user roles using role-based access control (RBAC).

General Information

  • Stream Name: Name of the selected stream.
  • Docs Count: Total number of ingested events.
  • Ingested Data: Uncompressed size of the stored data.
  • Compressed Size: Storage space used after compression.
  • Index Size: Size of the tantivy files generated for full text search index. Other index types, such as KeyValue filters and hash partitions, do not affect this value.
  • Start Time and End Time: Start time is the timestamp of the oldest data and end time is the timestamp of the newest data.

Note

  • If the ingested data has a _timestamp field, it will be according to that.
  • If the ingested data does not have a _timestamp field, then the start time will be the oldest time of ingestion and end time will be the newest time of ingestion.

Retention and Query Settings

  • Data Retention in Days: Sets how long data is retained in this stream. If not configured, the global retention period applies. By default, this is 30 days.

  • Max Query Range in Hours: Sets the maximum time span allowed per query. This can help reduce query load. Note that this is stream and org specific.

    You can set a global value as the maximum query range, for all streams across all organizations using the following environment variable: 

    ZO_DEFAULT_MAX_QUERY_RANGE_DAYS

    However, when a non-zero Max query range is set on a stream, the value set from the Stream Details panel overrides the global value.
    By default, both the environment variable and Max Query Range in the UI is set to zero (o), which means no limit.

  • Use Stream Stats for Partitioning: When you enable this toggle, OpenObserve assumes that all your data present in the stream is equally split and creates equal sized partitions between the start and end time.
