LMStats

Offline analysis of LMStudio server logs.

Quickly inspect your local LMStudio usage: token counts, per-model statistics, generation speeds, and daily breakdowns — all from your local ~/.lmstudio/server-logs directory.

Features

• Aggregate stats — total queries, prompt/completion tokens, average generation speed
• Per-model breakdown — queries, token counts, generation speed, and average latency per model
• Daily breakdown — usage trends across days with generation and wall-clock throughput
• Largest conversations — top conversations ranked by prompt tokens
• Slowest queries — identify the longest-running requests
• Time window filtering — analyze any custom time range with -H / --hours

How it works

LMStats reads log files from ~/.lmstudio/server-logs/, which LMStudio organizes by month. It parses each .log file for chat completion timing data and aggregates the results.

No network calls, no data leaves your machine.
