Prometheus metrics are empty

[apage43]

System Info

running with

docker run -p 8080:80 -v "${PWD}/data":/data --pull always ghcr.io/huggingface/text-embeddings-inference:cpu-1.6 --model-id nomic-ai/nomic-embed-text-v1.5

the service functions correctly, however /metrics successfully returns an empty response

$ curl -i localhost:8080/metrics
HTTP/1.1 200 OK
content-type: text/plain; charset=utf-8
vary: origin, access-control-request-method, access-control-request-headers
access-control-allow-origin: *
content-length: 0
date: Thu, 20 Mar 2025 23:10:29 GMT

(same can be repro'd building main and running text-embeddings-router directly)

Information

• Docker
• The CLI directly

Tasks

• An officially supported command
• My own modifications

Reproduction

1. run TEI with HTTP (any method)
2. request prometheus metrics - get blank response

Expected behavior

any metrics at all

i see - they are empty until measured requests have come in
