aspire otel command

Name

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

Synopsis

Aspire CLI

aspire otel [command] [options]

Description

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. By default, the subcommands discover a running AppHost and connect automatically. You can also use --dashboard-url to connect to a standalone dashboard directly — paste the full login URL (for example, http://localhost:18888/login?t=<token>) and the browser token is automatically exchanged for an API key.

Options

The following options are available:

• -?, -h, --help

• --non-interactive

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

• --nologo

  Suppress the startup banner and telemetry notice.
