Inspect TSI indexes

This page documents an earlier version of InfluxDB OSS. InfluxDB 3 Core is the latest stable version.

Use the influxd inspect command to inspect the InfluxDB time series index (TSI).

Output information about TSI index files

Use the influxd inspect dump-tsi command to output low-level details about TSI index (tsi1) files.

Provide the following:

influxd inspect dump-tsi \
  --series-file ~/.influxdbv2/engine/data/056d83f962a08461/_series \
  ~/.influxdbv2/engine/data/056d83f962a08461/autogen/1023/index

View example output

Output raw series data stored in the index

To output raw series data stored in index files, include the --series flag with the influxd inspect dump-tsi command:

influxd inspect dump-tsi \
  --series \
  --series-file ~/.influxdbv2/engine/data/056d83f962a08461/_series \
  ~/.influxdbv2/engine/data/056d83f962a08461/autogen/1023/index

View example output

Output measurement data stored in the index

To output measurement information stored in index files, include the --measurement flag with the influxd inspect dump-tsi command:

influxd inspect dump-tsi \
  --measurements \
  --series-file ~/.influxdbv2/engine/data/056d83f962a08461/_series \
  ~/.influxdbv2/engine/data/056d83f962a08461/autogen/1023/index

View example output

Export TSI index data as SQL

Use the influxd inspect export-index command to export an index in SQL format for easier inspection and debugging. Provide the following:

influxd inspect export-index \
  --series-path ~/.influxdbv2/engine/data/056d83f962a08461/_series \
  --index-path ~/.influxdbv2/engine/data/056d83f962a08461/autogen/1023/index

Report the cardinality of TSI files

Use the influxd inspect report-tsi command to output information about the cardinality of data in a bucket’s index. Provide the following:

  • --bucket-id with the ID of the bucket.
influxd inspect report-tsi --bucket-id 056d83f962a08461

New in InfluxDB 3.5

Key enhancements in InfluxDB 3.5 and the InfluxDB 3 Explorer 1.3.

See the Blog Post

InfluxDB 3.5 is now available for both Core and Enterprise, introducing custom plugin repository support, enhanced operational visibility with queryable CLI parameters and manual node management, stronger security controls, and general performance improvements.

InfluxDB 3 Explorer 1.3 brings powerful new capabilities including Dashboards (beta) for saving and organizing your favorite queries, and cache querying for instant access to Last Value and Distinct Value caches—making Explorer a more comprehensive workspace for time series monitoring and analysis.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On November 3, 2025, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
