influxd inspect report-db

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

The influxd inspect report-db command analyzes an InfluxDB bucket and reports the cardinality of data stored in the bucket.

Usage

influxd inspect report-db [flags]

Flags

FlagDescriptionInput Type
--cWorker concurrency (default is 1).integer
--db-path(Required) Path to InfluxDB data directory.string
--detailedInclude field and tag counts in output.
--exactReport exact counts.
-h--helpView help for the report-db command.
--rollupRollup level: t (total), b (bucket), r (retention policy), or m (measurement) (default).string

Examples

Report the cardinality of measurements in all buckets

# Syntax
influxd inspect report-db --db-path <influxdb-data-directory>

# Example
influxd inspect report-db --db-path ~/.influxdbv2/engine/data

Report the cardinality of measurements in a specific bucket

# Syntax
influxd inspect report-db --db-path <influxdb-data-directory>/<bucket-id>

# Example
influxd inspect report-db --db-path ~/.influxdbv2/engine/data/000xX00xxXx000x0

Report the cardinality of all buckets

  • Use the --db-path flag to provide the path to your InfluxDB data directory.
  • Use the --rollup flag with the value, b, to return a bucket-level summary of cardinality.
# Syntax
influxd inspect report-db \
  --db-path <influxdb-data-directory> \
  --rollup b

# Example
influxd inspect report-db \
  --db-path ~/.influxdbv2/engine/data \
  --rollup b

Report the cardinality of all retention policies

  • Use the --db-path flag to provide the path to your InfluxDB data directory.
  • Use the --rollup flag with the value, r, to return a retention-policy-level summary of cardinality.
# Syntax
influxd inspect report-db \
  --db-path <influxdb-data-directory> \
  --rollup r

# Example
influxd inspect report-db \
  --db-path ~/.influxdbv2/engine/data \
  --rollup r

Report the total cardinality of your InfluxDB instance

  • Use the --db-path flag to provide the path to your InfluxDB data directory.
  • Use the --rollup flag with the value, t, to return a summary of total cardinality.
# Syntax
influxd inspect report-db \
  --db-path <influxdb-data-directory> \
  --rollup t

# Example
influxd inspect report-db \
  --db-path ~/.influxdbv2/engine/data \
  --rollup t

Include tag and field counts in your cardinality summary

  • Use the --db-path flag to provide the path to your InfluxDB data directory.
  • Include the --detailed flag to return detailed cardinality summaries with tag and field counts.
# Syntax
influxd inspect report-db \
  --db-path <influxdb-data-directory> \
  --detailed

# Example
influxd inspect report-db \
  --db-path ~/.influxdbv2/engine/data \
  --detailed

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 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
