Two documented ways to store InfluxDB line protocol in Grafana Cloud Metrics

Estimated time: 1 min

InfluxDB

Grafana Cloud can store InfluxDB line protocol in Grafana Cloud Metrics in two ways. A third option, the InfluxDB data source, queries InfluxDB where it already lives and does not store a copy.

InfluxDB line protocol reaches Grafana Cloud Metrics through influxdb_exporter or Telegraf

Option 1: influxdb_exporter

Use this when you want Prometheus to scrape InfluxDB metrics and remote-write them.

  • Install influxdb_exporter on the system where InfluxDB runs. It exposes an endpoint Prometheus can scrape.
  • Prometheus scrapes that endpoint and sends the samples with remote_write.
  • You run both the exporter and Prometheus.

Option 2: Telegraf

Use this when Telegraf, or another client, already pushes Influx line protocol.

  • Point Telegraf’s InfluxDB output at your metrics write endpoint plus /api/v1/push/influx.
  • Grafana Cloud converts each line-protocol field into a Prometheus series named metric_name_field.
  • Set skip_database_creation = true. The Grafana Cloud Influx write endpoint does not support creating databases, and Telegraf tries to create one by default.
