influxd inspect report-db

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

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
