vLLora CLI

The vLLora CLI brings the core functionality of the vLLora MCP server to the terminal. It’s designed for fast iteration, local reproduction, and automation workflows where you want direct command-line access to traces, exports, and recent failures.

Quick Start

The core workflow is:

Find a trace

vllora traces list --last-n-minutes 60 --limit 20

Commands

traces list

Search/list traces by various criteria.

vllora traces list [OPTIONS]

Options:

• --limit <LIMIT> - Limit number of results (default: 20)
• --offset <OFFSET> - Offset for pagination (default: 0)
• --run-id <RUN_ID> - Filter by run ID
• --thread-id <THREAD_ID> - Filter by thread ID

• --last-n-minutes <LAST_N_MINUTES> - Filter traces from last N minutes
• --sort-by <SORT_BY> - Sort by field (default: start_time)
• --sort-order <SORT_ORDER> - Sort order: asc or desc (default: desc)
• --output <OUTPUT> - Output format: table or json (default: table)

Example:

vllora traces list --last-n-minutes 60 --limit 20

traces call-info

Get detailed LLM call information for a span.

vllora traces call-info --span-id <SPAN_ID> [OPTIONS]

Options:

• --span-id <SPAN_ID> - Span ID (required)
• --output <OUTPUT> - Output format: table or json (default: table)

vllora traces run-info --run-id <RUN_ID> [OPTIONS]

Options:

• --run-id <RUN_ID> - Run ID (required)
• --output <OUTPUT> - Output format: table or json (default: table)

Example:

vllora traces run-info --run-id 4ea18f79-4c4c-4d2c-b628-20d510af7181

When to Use CLI vs Other Methods

The CLI is ideal for:

• Terminal workflows - Quick checks without leaving your terminal
• Scripts and automation - Monitoring, reporting. Use --output json with shell redirection to export: vllora traces list --last-n-minutes 60 --output json > traces.json
• Local reproduction - Exporting trace data for debugging
• Bulk operations - Processing many traces at once

For visual exploration and deep dives, use the Web UI. For debugging from coding agents or IDE tools, use the MCP Server.
