LLM Usage Metrics

qwen Source

Default location

Section titled “Default location”
  • ~/.qwen/projects/*/chats/*.jsonl

Override

Section titled “Override”
Terminal window
llm-usage daily --source qwen --qwen-dir /path/to/.qwen/projects

qwen is directory-backed, so generic source directory overrides also work:

Terminal window
llm-usage daily --source-dir qwen=/path/to/.qwen/projects

The adapter does not read QWEN_DATA_DIR in this release; use --qwen-dir for non-default locations.

Parsing notes

Section titled “Parsing notes”

The adapter reads Qwen CLI JSONL chat rows. Assistant rows with usageMetadata become usage events: promptTokenCount maps to input, candidatesTokenCount to output, thoughtsTokenCount to reasoning, cachedContentTokenCount to cache read, and totalTokenCount to the declared total when present.
