Hi all,
I’m trying to push OTel metrics into Prometheus according to OpenTelemetry | Prometheus.
I’m running prometheus:v3.0.1 docker image locally, here is the full config
prometheus:
image: prom/prometheus:v3.0.1
extra_hosts: [ 'host.docker.internal:host-gateway' ]
volumes:
- prometheus:/prometheus
- ./prometheus/:/etc/prometheus/
command:
- --web.enable-otlp-receiver
- --enable-feature=exemplar-storage
- --web.enable-remote-write-receiver
- --config.file=/etc/prometheus/prometheus-${profile:-dev}.yml
- --log.level=debug
ports:
- 9090:9090
with Prometheus configuration
storage:
tsdb:
out_of_order_time_window: 1m
otlp:
promote_resource_attributes:
- service.name
translation_strategy: NoUTF8EscapingWithSuffixes
I can confirm (through Wireshark) my Spring Boot 3.4 app is successfully exporting metrics to HTTP /api/v1/otlp/v1/metrics endpoint, and it gets HTTP 200 OK response from Prometheus.
The problem is there are no metrics in Prometheus. I’m lost as there is no error message or anything indicating what could be wrong. Did anybody else successfully setup OTLP receiver in Prometheus, or is this still a work in progress feature?
Thank you!
