Send Prometheus metrics

If your services expose a Prometheus /metrics endpoint (an exporter such as node_exporter, redis_exporter, nginx-prometheus-exporter or kafka_exporter, or your own application), the OpenTelemetry Collector can scrape it and send the metrics to Televane. You keep your existing exporters and scrape settings, and you don't need Prometheus or a Televane agent.

1. Create an ingest token

1. In the portal open Administration › API keys and create a token with the ingest scope.
2. Copy it (it starts with obs_). It is shown once — keep it in your secret store, not in source code.

2. Configure the Collector

Use the contrib distribution of the OpenTelemetry Collector (otelcol-contrib), which includes the Prometheus receiver. The scrape_configs section uses Prometheus syntax, so you can paste in the jobs from your prometheus.yml:

receivers:
  prometheus:
    config:
      scrape_configs:
        - job_name: node
          scrape_interval: 30s
          static_configs:
            - targets: ["10.0.0.11:9100", "10.0.0.12:9100"]
        - job_name: redis
          scrape_interval: 30s
          static_configs:
            - targets: ["10.0.0.20:9121"]

processors:
  batch: {}

exporters:
  otlphttp/televane:
    endpoint: https://ingest.televane.com
    headers:
      Authorization: "Bearer ${env:TELEVANE_TOKEN}"

service:
  pipelines:
    metrics: { receivers: [prometheus], processors: [batch], exporters: [otlphttp/televane] }

Start the Collector with the token in its environment, for example TELEVANE_TOKEN=obs_YOUR_TOKEN otelcol-contrib --config collector.yaml.

What you will see

• In Metrics › Custom metrics: every scraped metric with its labels (job, instance and the exporter's own labels). You can filter and group on them, chart them and alert on them.
• Counters, gauges, histograms and summaries all arrive.

Good to know

• Custom metrics are part of Pro and above, and of the 14-day Pro trial that every new account starts with.
• A 30-second scrape interval is a good default. Each scraped series counts toward your data volume and your series limit, so use the Collector's filter processor or Televane's pipeline rules to drop metrics you don't need.
• Televane doesn't accept Prometheus remote write or run PromQL. Queries use the Custom metrics query builder.
• Exponential (native) histograms are not supported yet; exporters send classic bucket histograms by default.
• To send traces and logs as well, see Send OpenTelemetry data.
