SPM doesn't show data

[vitalykarasik]

I'm trying to activate SPM based on https://www.jaegertracing.io/docs/1.35/spm/, and getting "No data yet! ".
According to the doc, we should configure jaeger-query to use the Prometheus backend for metrics. But the doc doesn't mention jaeger-collector...
Shouldn't we point jaeger-collector to the Prometheus as well?

Thanks, Vitaly

The components you need are:

• OpenTelemetry Collector that will receive traces, with its pipeline configured (example) with:
  • spanmetrics processor
  • prometheus exporter (pointing to the prometheus component below)
• Prometheus-compatible server that will receive metrics from OpenTelemetry Collector.
• Jaeger-query that will read metrics from the Prometheus-compatible server above.

You'll then need to send spans to OpenTelemetry collector and metrics should be visible in the SPM view of Jaeger UI.

Technically, jaeger-collector is not necessary at all to view metrics in SPM.

OpenTelemetry Collector that will receive traces
So this is an additional component, not from Jaeger project?

thank you, Vitaly

Yes, that's correct: https://opentelemetry.io/docs/collector/getting-started/
