aspire otel command

aspire otel - View OpenTelemetry data (logs, spans, traces) from a running apphost.

Aspire CLI
aspire otel [command] [options]

The aspire otel command provides subcommands for viewing OpenTelemetry data collected by the Aspire Dashboard from a running AppHost. You can view structured logs, distributed trace spans, and trace summaries directly from the terminal.

The data is retrieved from the Dashboard’s telemetry API, so an AppHost must be running with the Dashboard enabled.

The following options are available:

  • -?, -h, --help

    Prints help and usage documentation for the available commands and options.

  • -l, --log-level <Critical|Debug|Error|Information|None|Trace|Warning>

    Set the minimum log level for console output. Use this option to increase diagnostics while troubleshooting or reduce output in scripted runs.

  • --non-interactive

    Run the command in non-interactive mode, disabling all interactive prompts and spinners.

  • --nologo

    Suppress the startup banner and telemetry notice.

  • --banner

    Display the animated Aspire CLI welcome banner.

  • --wait-for-debugger

    Wait for a debugger to attach before running a command.
