Documentation Grafana Tempo Set up for tracing Set up Tempo Command line flags

Command line flags

Tempo provides various command-line flags to configure its behavior when starting the binary. This document serves as a reference for these flags.

Global flags

Target flag

The deployment mode is determined by the runtime configuration target, or by using the -target flag on the command line. The default target is all, which is the monolithic deployment mode.

Refer to the Plan your Tempo deployment documentation for information on deployment modes.

Authentication and multitenancy

HTTP and API settings

Server settings

Memberlist settings

Module configuration

You can use additional flags to configuring individual Tempo modules, such as the distributor, ingester, querier, and their components. These flags follow a pattern like --<module>.<setting> and are extensively documented in the configuration file format.

Use the configuration file approach described in the Configuration documentation. The documentation has a comprehensive list of all configuration options.

Usage examples

Start Tempo with a configuration file:

Bash Copy

tempo --config.file=/etc/tempo/config.yaml

Start Tempo with a specific target:

Bash Copy

tempo --target=distributor --config.file=/etc/tempo/config.yaml

Verify configuration without starting Tempo:

Bash Copy
