Influx Inspect

Influx Inspect is a tool designed to view detailed information about on disk shards, as well as export data from a shard to line protocol that can be inserted back into the database.

influx_inspect

Will print usage for the tool.

influx_inspect report

Displays series meta-data for all shards. The default location is [$HOME/.influxdb].

influx_inspect dumptsm

Dumps low-level details about tsm files.

Flags

-index bool

Dump raw index data.

default = false

-blocks bool

Dump raw block data.

default = false

-all

Dump all data. Caution: This may print a lot of information.

default = false

-filter-key

Only display index and block data that match this key substring.

default = “”

influx_inspect export

Exports all tsm files to line protocol. This output file can be imported via the influx command.

-datadir string

Data storage path.

default = “$HOME/.influxdb/data”

-waldir string

WAL storage path.

default = “$HOME/.influxdb/wal”

-out string

Destination file to export to

default = “$HOME/.influxdb/export”

-database string (optional)

Database to export.

default = “”

-retention string (optional)

Retention policy to export.

default = “”

-start string (optional)

The start of the time range. The date-time string must be RFC3339 format.

-end string (optional)

The end of the time range. The date-time string must be RFC3339 format.

-compress bool (optional)

Compress the output.

default = false

Sample Commands

Export entire database and compress the output:

influx_inspect export -compress

Export data from a specific database and retention policy:

influx_inspect export -database mydb -retention autogen

Sample Data

This is a sample of what the output will look like.

# DDL
CREATE DATABASE MY_DB_NAME
CREATE RETENTION POLICY autogen ON MY_DB_NAME DURATION inf REPLICATION 1

# DML
# CONTEXT-DATABASE:MY_DB_NAME
# CONTEXT-RETENTION-POLICY:autogen
randset value=97.9296104805 1439856000000000000
randset value=25.3849066842 1439856100000000000

Caveats

The system does not have access to the meta store when exporting TSM shards. As such, it always creates the retention policy with infinite duration and replication factor of 1. End users may want to change this prior to re-importing if they are importing to a cluster or want a different duration for retention.
