Hello Everyone,
Recently I’m trying to connect Loki as a datasource to grafana but I’m receiving this error:
Data source connected, but no labels received. Verify that Loki and Promtail is configured properly.
This is my opentelemetry collector configuration:
receivers:
otlp:
protocols:
grpc:
http:
processors:
attributes:
actions:
- action: insert
key: loki.attribute.labels
value: http.status_code
resource:
attributes:
- action: insert
key: loki.attribute.labels
value: http.status
- action: insert
key: loki.resource.labels
value: host.name, pod.name
batch:
memory_limiter:
# 80% of maximum memory up to 2G
limit_mib: 1500
# 25% of limit up to 2G
spike_limit_mib: 512
check_interval: 5s
extensions:
zpages: {}
memory_ballast:
# Memory Ballast size should be max 1/3 to 1/2 of memory.
size_mib: 683
exporters:
otlp:
endpoint: "grafana-tempo.grafana-labs:4317" # Replace with a real endpoint.
tls:
insecure: true
prometheus:
endpoint: "0.0.0.0:8889"

loki:
endpoint: "http://loki-nodeport.grafana-labs:3100/loki/api/v1/push"
tls:
insecure: true
service:
extensions: [zpages, memory_ballast]
pipelines:
traces:
receivers: [otlp]
processors: [memory_limiter, batch]
exporters: [otlp,jaeger]
logs:
receivers: [otlp]
processors: [memory_limiter, batch, attributes, resource]
exporters: [otlp,loki]
metrics:
receivers: [otlp]
processors: [memory_limiter, batch]
exporters: [prometheus]
The questions are:
Is there something else to configure here in this configuration?
Opentelemetry collector can send data directly to Loki without Promtail? If no what exporter should I use?.
Thanks in Advance.
