The influxd inspect report-tsm command analyzes Time-Structured Merge Tree (TSM) files within a storage engine directory and reports the cardinality within the files and the time range the data covers.

This command only interrogates the index within each file. It does not read any block data. To reduce heap requirements, by default report-tsm estimates the overall cardinality in the file set by using the HLL++ algorithm. Determine exact cardinalities by using the --exact flag.

Usage

influxd inspect report-tsm [flags]

Output details

influxd inspect report-tsm outputs the following for each file:

  • The full file name.
  • The series cardinality within the file.
  • The number of series first encountered within the file.
  • The minimum and maximum timestamp associated with TSM data in the file.
  • The time to load the TSM index and apply any tombstones.

The summary section then outputs the total time range and series cardinality for the file set. Depending on the --detailed flag, series cardinality is segmented in the following ways:

  • Series cardinality for each organization.
  • Series cardinality for each bucket.
  • Series cardinality for each measurement.
  • Number of field keys for each measurement.
  • Number of tag values for each tag key.

Flags

Flag Description Input Type
--bucket-id Process only data belonging to bucket ID. Requires org-id flag to be set. string
--data-dir Use provided data directory (defaults to ~/.influxdbv2/engine/data). string
--detailed Emit series cardinality segmented by measurements, tag keys, and fields. May take a while.
--exact Calculate an exact cardinality count. May use significant memory.
-h, --help Help for report-tsm.
--org-id Process only data belonging to organization ID. string
--pattern Only process TSM files containing pattern. string
