Tempo CLI

Tempo CLI

Tempo CLI is a separate executable that contains utility functions related to the tempo software. Although it is not required for a working installation, Tempo CLI can be helpful for deeper analysis or for troubleshooting.

Tempo CLI command syntax

The general syntax for commands in Tempo CLI is:

tempo-cli command [subcommand] [options] [arguments...]

--help or -h displays the help for a command or subcommand.


tempo-cli -h
tempo-cli command [subcommand] -h

Running Tempo CLI

Tempo CLI is currently available as source code. A working Go installation is required to build it. It can be compiled to a native binary and executed normally, or it can be executed using the go run command.


./tempo-cli [arguments...]
go run ./cmd/tempo-cli [arguments...]

Backend options

Tempo CLI connects directly to the storage backend for some commands, meaning that it requires the ability to read from S3, GCS, Azure or file-system storage. The backend can be configured in a few ways:

  • Load an existing tempo configuration file using the --config-file (-c) option. This is the recommended option for frequent usage. Refer to Configuration documentation for more information.
  • Specify individual settings:
    • --backend <value> The storage backend type, one of s3, gcs, azure, and local.
    • --bucket <value> The bucket name. The meaning of this value is backend-specific. Refer to Configuration documentation for more information.
    • --s3-endpoint <value> The S3 API endpoint (i.e. s3.dualstack.us-east-2.amazonaws.com).
    • --s3-user <value>, --s3-password <value> The S3 user name and password (or access key and secret key). Optional, as Tempo CLI supports the same authentication mechanisms as Tempo. See S3 permissions documentation for more information.

Each option applies only to the command in which it is used. For example, --backend <value> does not permanently change where Tempo stores data. It only changes it for command in which you apply the option.

Query Command

Call the tempo API and retrieve a trace by ID.

tempo-cli query <api-endpoint> <trace-id>


  • api-endpoint URL for tempo API.
  • trace-id Trace ID as a hexadecimal string.


  • --org-id <value> Organization ID (for use in multi-tenant setup).


tempo-cli query http://tempo:3100 f1cfe82a8eef933b

List Blocks

Lists information about all blocks for the given tenant, and optionally perform integrity checks on indexes for duplicate records.

tempo-cli list blocks <tenant-id>


  • tenant-id The tenant ID. Use single-tenant for single tenant setups.


  • --include-compacted Include blocks that have been compacted. Default behavior is to display only active blocks.
  • --load-index Also load the block indexes and perform integrity checks for duplicates. Note: This can be a resource intensive process.

Output: Explanation of output:

  • ID Block ID.
  • Lvl Compaction level of the block.
  • Count Number of objects stored in the block.
  • Window The window of time that was considered for compaction purposes.
  • Start The earliest timestamp stored in the block.
  • End The latest timestamp stored in the block.
  • Age The age of the block.
  • DurationDuration between the start and end time.
  • Idx Number of records stored in the index (present when –load-index is specified).
  • Dupe Number of duplicate entries in the index (present when –load-index is specified). Should be zero.
  • Cmp Whether the block has been compacted (present when –include-compacted is specified).


tempo-cli list blocks -c ./tempo.yaml single-tenant

List Block

Lists information about a single block, and optionally, scan its contents.

tempo-cli list block <tenant-id> <block-id>


  • tenant-id The tenant ID. Use single-tenant for single tenant setups.
  • block-id The block ID as UUID string.


  • --scan Also load the block data, perform integrity check for duplicates, and collect statistics. Note: can be intense.


tempo-cli list block -c ./tempo.yaml single-tenant ca314fba-efec-4852-ba3f-8d2b0bbf69f1
