influxd inspect report-tsm
This page documents an earlier version of InfluxDB OSS. InfluxDB 3 Core is the latest stable version.
API token hashing is enabled by default in InfluxDB OSS 2.9.0
Stronger token security: tokens are stored as hashes on disk, so a copy of the database file doesn’t expose usable tokens. Existing tokens are hashed on first startup and the original strings can’t be recovered afterward — capture any plaintext tokens you still need before you upgrade.
For more information, see Token hashing.
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 reports on the index within each TSM 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 TSM 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 | |
|---|---|---|---|
--data-path | Path to 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 the report-tsm command. | |
--pattern | Only process TSM files containing pattern. | string |
