@Jonathan Berrios have you checked this - https://signoz.io/docs/userguide/send-metrics/#enable-a-prometheus-receiver

@Pranay yes but I would need to enable a Prometheus receiver from the Otel Collector that I have setup outside Signoz. In the same way as I did with the infra metrics, but for Prometheus receiver. I thought do I need to use your custom image version to target

clickhousemetricswrite

exporter to achieve this ? I appreciate your help,

@Prashant Shahi @Ankit Nayan Do you have insights on this?

@Jonathan Berrios you can decide on either of the following ways to send your prometheus metrics to SigNoz. • include your prometheus metrics's endpoint in prometheus receiver of SigNoz Otel Collector Metrics configuration • set up SigNoz OtelCollector with prometheus receiver configuration and send it to SigNoz clickhouse directly using

clickhousemetricswrite

exporter • set up another collector (SigNoz OtelCollector or OpenTelemetry Collector of v0.43.0) and configure prometheus receiver configuration and relay it to SigNoz OTLP receiver

@Jonathan Berrios I don't think I got your question correctly. Let me try to explain a few points and you can ask more specific things.

clickhousemetricswrite

exporter and hence signoz's version of otel-collector will be needed when writing to clickhouse.

prometheusreveiver

can be used in both signoz's otel-collector or the upstream. You can set prometheus scrape config at 2 places: 1. At

otel-collector-metrics

running as part of signoz which can then write the scraped data to clickhouse using

clickhousemetricswrite

2. At

otel-collector

which is not part of signoz. It can run in every node or as deployment just like prometheus in any cluster/region. You need to specify scrape configs at

prometheusreceiver

there and use

otlpexporter

to send metrics to signoz's

otel-collector

which can then write to clickhouse using

clickhousemetricswrite

exporter which is available in signoz's distribution of otel-collector

@Ankit Nayan @Prashant Shahi @Pranay Thank you, the option 2 is what we aim for. When setting 2 jobs/targets for my

prometheus

receiver it cannot connect because it only listens to port

8888

and not

8080

, which I need, I believe this is more Otel side but could you recommend a way so I listen to both ports ? Very appreciated,
