Inspect TSI indexes
Use the influxd inspect command to inspect the InfluxDB time series index (TSI).
- Output information about TSI index files
- Export TSI index data as SQL
- Report the cardinality of TSI files
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:
- (Required)
--series-fileflag with the path to bucket’s_seriesdirectory. - (Required) Path to the shard’s
indexdirectory
influxd inspect dump-tsi \
--series-file ~/.influxdbv2/engine/data/056d83f962a08461/_series \
~/.influxdbv2/engine/data/056d83f962a08461/autogen/1023/index
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
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:
--series-pathflag with the path to the bucket’s_seriesdirectory.--index-pathflag with the path to the shard’sindexdirectory.
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-idwith the ID of the bucket.
influxd inspect report-tsi --bucket-id 056d83f962a08461
