# OpenLIT — LLM observability (traces, costs, KV-cache, prompt/decode
# latencies, tokens/sec). https://openlit.io
#
# Two services:
#   - clickhouse  : columnar store for traces (internal only, no host port)
#   - openlit     : Next.js UI on :3001 (3000 is OpenWebUI)
#
# Why OpenLIT vs Langfuse/Phoenix/Laminar: it's the only OSS dashboard
# (May 2026) that auto-instruments Ollama AND vLLM via OpenTelemetry
# without adding code to client apps. For llama.cpp, start the server
# with --metrics (see ../llama/docker-compose.yml) and OpenLIT can scrape
# /metrics.
#
# To send traces from a Python script calling Ollama/vLLM:
#   pip install openlit
#   python -c "import openlit; openlit.init(otlp_endpoint='http://framework:4318')"
#
# To wire OpenWebUI → OpenLIT, install OpenLIT's pipeline middleware
# in OpenWebUI per https://openlit.io/blogs/openlit-openwebui.
