@Ankit Nayan may have more ideas on this

Hi @avtar singh 👋 You can relay it as OTLP format to SigNoz while running OpenTelemetry collector instance else where. If you are looking for something equivalent for

prometheusremotewrite

, it would be

clickhousemetricswrite

however, you would have to run SigNoz OtelCollector image and pass ClickHouse credentials. https://github.com/SigNoz/signoz/blob/develop/deploy/docker/clickhouse-setup/otel-collector-metrics-config.yaml#L57-L59 https://github.com/SigNoz/charts/blob/main/charts/signoz/values.yaml#L1172-L1174

Hi @Prashant Shahi. Thank you for the input I will try OTLP way

@avtar singh which remote prometheus storage do you wise to write using

prometheusremotewrite

? Ideally you should not need with signoz setup

avtar singh

I am writing to thanos

Ankit Nayan

08/04/2022, 4:46 AM

you can still use the

prometheusremotewrite

exporter to write to thanos. That would just be an additional config to add to otel-collector exporters https://github.com/SigNoz/opentelemetry-collector-contrib/tree/develop/exporter/prometheusremotewriteexporter

Ankit Nayan

but why do you want to use thanos with signoz? SigNoz itself is a central hub for all telemetry data including metrics. Different otel-collectors with different scrape configs in prometheus receiver and writing to clickhouse as signoz comes with default settings should be good enough unless you are running prometheus in HA mode (multiple prometheus instances scraping same set of metrics). We have not enabled de-duplication of data yet in signoz

but multiple prometheus instances scraping different configs (or multiple otel-collectors with different scrape configs in prometheus receiver) should write all data in clickhouse and you can query all metrics from signoz's UI which acts as centralized view of all data

with prometheusremotewrite I was getting 404

with prometheusremotewrite I was getting 404

there would be config or thanos set up issue. SigNoz uses otel-collector which enables writing via

prometheusremotewrite

avtar singh

08/04/2022, 4:52 AM

okay I will try it again.

totally unrelated question does the vanilla Prometheus support direct write ?

Ankit Nayan

08/04/2022, 4:56 AM

vanilla Prometheus support direct write

you mean write to thanos? Yes

avtar singh

08/04/2022, 4:57 AM

direct write to prometheus without thanos

Ankit Nayan

08/04/2022, 5:30 AM

you will need to use

prometheusexporter

at otel-collector https://github.com/SigNoz/opentelemetry-collector-contrib/tree/develop/exporter/prometheusexporter which will expose at some endpoint and then prometheus can scrape the otel-collectors to get the metrics

but everything above is not tested to work with signoz as we try to be complete replacement to all stacks of observability
