+# `influx_inspect`
+
+## Ways to run
+
+### `influx_inspect`
+Will print usage for the tool.
+
+### `influx_inspect report`
+Displays series meta-data for all shards.  Default location [$HOME/.influxdb]
+
+### `influx_inspect dumptsm`
+Dumps low-level details about tsm1 files
+
+#### Flags
+
+##### `-index` bool
+Dump raw index data.
+
+`default` = false
+
+#### `-blocks` bool
+Dump raw block data.
+
+`default` = false
+
+#### `-all`
+Dump all data. Caution: This may print a lot of information.
+
+`default` = false
+
+#### `-filter-key`
+Only display index and block data match this key substring.
+
+`default` = ""
+
+
+### `influx_inspect export`
+Exports all tsm files to line protocol.  This output file can be imported via the [influx](https://github.com/influxdata/influxdb/tree/master/importer#running-the-import-command) command.
+
+
+#### `-datadir` string
+Data storage path.
+
+`default` = "$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)
+Optional. The time range to start at.
+
+#### `-end` string (optional)
+Optional. The time range to end at.
+
+#### `-compress` bool (optional)
+Compress the output.
+
+`default` = false
+
+#### Sample Commands
+
+Export entire database and compress output:
+```
+influx_inspect export --compress
+```
+
+Export specific 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.
