Production Metrics
|
|
==================
|
|
|
|
vLLM exposes a number of metrics that can be used to monitor the health of the
|
|
system. These metrics are exposed via the ``/metrics`` endpoint on the vLLM
|
|
OpenAI compatible API server.
|
|
|
|
You can start the server using Python, or using [Docker](deploying_with_docker.rst):
|
|
|
|
.. code-block:: console
|
|
|
|
$ vllm serve unsloth/Llama-3.2-1B-Instruct
|
|
|
|
Then query the endpoint to get the latest metrics from the server:
|
|
|
|
.. code-block:: console
|
|
|
|
$ curl http://0.0.0.0:8000/metrics
|
|
|
|
# HELP vllm:iteration_tokens_total Histogram of number of tokens per engine_step.
|
|
# TYPE vllm:iteration_tokens_total histogram
|
|

|
|
