Documentation Grafana Agent Flow mode Reference Command-line interface convert

The convert command

The convert command converts a supported configuration format to Grafana Agent Flow River format.

Usage

Usage:

• AGENT_MODE=flow grafana-agent convert [<FLAG> ...] <FILE_NAME>

• grafana-agent-flow convert [<FLAG> ...] <FILE_NAME>

  Replace the following:

  • <FLAG>: One or more flags that define the input and output of the command.
  • <FILE_NAME>: The Grafana Agent configuration file.

If the FILE_NAME argument isn’t provided or if the FILE_NAME argument is equal to -, convert converts the contents of standard input. Otherwise, convert reads and converts the file from disk specified by the argument.

There are several different flags available for the convert command. You can use the --output flag to write the contents of the converted configuration to a specified path. You can use the --report flag to generate a diagnostic report. The --bypass-errors flag allows you to bypass any errors generated during the file conversion.

The command fails if the source configuration has syntactically incorrect configuration or can’t be converted to Grafana Agent Flow River format.

The following flags are supported:

• --output, -o: The filepath and filename where the output is written.

• --report, -r: The filepath and filename where the report is written.

• --source-format, -f: Required. The format of the source file. Supported formats: otelcol, prometheus, promtail, static.

• --bypass-errors, -b: Enable bypassing errors when converting.

• --extra-args, e: Extra arguments from the original format used by the converter.

Defaults

Grafana Agent Flow defaults are managed as follows:

• If a provided source configuration value matches a Grafana Agent Flow default value, the property is left off the output.
• If a non-provided source configuration value default matches a Grafana Agent Flow default value, the property is left off the output.
• If a non-provided source configuration value default doesn’t match a Grafana Agent Flow default value, the default value is included in the output.

Errors

Errors are defined as non-critical issues identified during the conversion where an output can still be generated. These can be bypassed using the --bypass-errors flag.

OpenTelemetry Collector

You can use the --source-format=otelcol to convert the source configuration from an OpenTelemetry Collector to a Grafana Agent Flow configuration.

Many OpenTelemetry Collector components are supported. Review the otelcol.* component information in the Component Reference for more information about otelcol components that you can convert. If a source configuration has unsupported features, you will receive errors when you convert it to a flow configuration. The converter raises warnings for configuration options that may require your attention.

Refer to Migrate from OpenTelemetry Collector to Grafana Agent Flow for a detailed migration guide.

Prometheus

Using the --source-format=prometheus will convert the source configuration from Prometheus v2.45 to Grafana Agent Flow configuration.

This includes Prometheus features such as scrape_config, relabel_config, metric_relabel_configs, remote_write, and many supported *_sd_configs. Unsupported features in a source configuration result in errors.

Refer to Migrate from Prometheus to Grafana Agent Flow for a detailed migration guide.

Promtail

Using the --source-format=promtail will convert the source configuration from Promtail v2.8.x to Grafana Agent Flow configuration.

Nearly all Promtail features are supported and can be converted to Grafana Agent Flow configuration.

If you have unsupported features in a source configuration, you will receive errors when you convert to a flow configuration. The converter will also raise warnings for configuration options that may require your attention.

Refer to Migrate from Promtail to Grafana Agent Flow for a detailed migration guide.

Static

Using the --source-format=static will convert the source configuration from a Grafana Agent Static configuration to a Grafana Agent Flow configuration.

Include --extra-args for passing additional command line flags from the original format. For example, --extra-args="-enable-features=integrations-next" will convert a Grafana Agent Static integrations-next configuration to a Grafana Agent Flow configuration. You can also expand environment variables with --extra-args="-config.expand-env". You can combine multiple command line flags with a space between each flag, for example --extra-args="-enable-features=integrations-next -config.expand-env".

If you have unsupported features in a Static mode source configuration, you will receive errors when you convert to a Flow mode configuration. The converter will also raise warnings for configuration options that may require your attention.
