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

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

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On February 3, 2026, 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
