Deployment and OperationsTempo 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.

Example:

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.

Example:

./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 API Command

Call the tempo API and retrieve a trace by ID.

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

Arguments:

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

Options:

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

Example:

tempo-cli query api http://tempo:3200 f1cfe82a8eef933b

Query Blocks Command

Iterate over all backend blocks and dump all data found for a given trace id.

tempo-cli query blocks <trace-id> <tenant-id>

Note: can be intense as it downloads every bloom filter and some percentage of indexes/trace data.

Arguments:

  • trace-id Trace ID as a hexadecimal string.
  • tenant-id Tenant to search.

Options: See backend options above.

Example:

tempo-cli query blocks f1cfe82a8eef933b single-tenant

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>

Arguments:

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

Options:

  • --include-compacted Include blocks that have been compacted. Default behavior is to display only active blocks.

Output: Explanation of output:

  • ID Block ID.
  • Lvl Compaction level of the block.
  • Objects Number of objects stored in the block.
  • Size Data size of the block after any compression.
  • Encoding Block encoding (compression algorithm).
  • Vers Block version.
  • 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.
  • DurationDuration between the start and end time.
  • Age The age of the block.
  • Cmp Whether the block has been compacted (present when –include-compacted is specified).

Example:

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>

Arguments:

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

Options:

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

Example:

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

List Compaction Summary

Summarizes information about all blocks for the given tenant based on compaction level. This command is useful to analyze or troubleshoot compactor behavior.

tempo-cli list compaction-summary <tenant-id>

Arguments:

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

Example:

tempo-cli list compaction-summary -c ./tempo.yaml single-tenant

List Cache Summary

Prints information about the number of bloom filter shards per day per compaction level. This command is useful to estimate and fine-tune cache storage. Read the caching topic for more information.

tempo-cli list cache-summary <tenant-id>

Arguments:

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

Example:

tempo-cli list cache-summary -c ./tempo.yaml single-tenant

List Index

Lists basic index info for the given block.

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

Arguments:

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

Example:

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

View Index

View the index contents for the given block.

tempo-cli view index <tenant-id> <block-id>

Arguments:

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

Example:

tempo-cli view index -c ./tempo.yaml single-tenant ca314fba-efec-4852-ba3f-8d2b0bbf69f1

Generate Bloom Filter

To generate the bloom filter for a block if the files were deleted/corrupted.

Note: ensure that the block is in a local backend in the expected directory hierarchy, i.e. path / tenant / blocks.

Arguments:

  • tenant-id The tenant ID. Use single-tenant for single tenant setups.
  • block-id The block ID as UUID string.
  • bloom-fp The false positive to be used for the bloom filter.
  • bloom-shard-size The shard size to be used for the bloom filter.

Example:

tempo-cli gen bloom --backend=local --bucket=./cmd/tempo-cli/test-data/ single-tenant b18beca6-4d7f-4464-9f72-f343e688a4a0 0.05 100000

The bloom filter will be generated at the required location under the block folder.

Generate Index

To generate the index/bloom for a block if the files were deleted/corrupted.

Note: ensure that the block is in a local backend in the expected directory hierarchy, i.e. path / tenant / blocks.

Arguments:

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

Example:

tempo-cli gen index --backend=local --bucket=./cmd/tempo-cli/test-data/ single-tenant b18beca6-4d7f-4464-9f72-f343e688a4a0

The index will be generated at the required location under the block folder.

Search Blocks Command

Search blocks in a given time range for a specific key/value pair.

tempo-cli search blocks <name> <value> <start> <end> <tenant-id>

Note: can be intense as it downloads all relevant blocks and iterates through them.

Arguments:

  • name Name of the attribute to search for e.g. http.post
  • value Value of the attribute to search for e.g. GET
  • start Start of the time range to search: (YYYY-MM-DDThh:mm:ss)
  • end End of the time range to search: (YYYY-MM-DDThh:mm:ss)
  • tenant-id Tenant to search.

Options: See backend options above.

Example:

tempo-cli search blocks http.post GET 2021-09-21T00:00:00 2021-09-21T00:05:00 single-tenant --backend=gcs --bucket=tempo-trace-data
