Scrape Prometheus metrics

Use Telegraf or the prometheus.scrape Flux function to scrape Prometheus-formatted metrics from an HTTP-accessible endpoint and store them in InfluxDB.

Use Telegraf

To use Telegraf to scrape Prometheus-formatted metrics from an HTTP-accessible endpoint and write them to InfluxDB Cloud, follow these steps:

  1. Add the Prometheus input plugin to your Telegraf configuration file.
    1. Set the urls to scrape metrics from.
    2. Set the metric_version configuration option to specify which metric parsing version to use (version 2 is recommended).
  2. Add the InfluxDB v2 output plugin to your Telegraf configuration file and configure it to write to InfluxDB Cloud.
Example telegraf.conf
# ...

## Collect Prometheus formatted metrics
[[inputs.prometheus]]
  urls = ["http://example.com/metrics"]
  metric_version = 2

## Write Prometheus formatted metrics to InfluxDB
[[outputs.influxdb_v2]]
  urls = ["http://localhost:8086"]
  token = "$INFLUX_TOKEN"
  organization = "example-org"
  bucket = "example-bucket"

# ...

Use prometheus.scrape()

To use the prometheus.scrape() Flux function to scrape Prometheus-formatted metrics from an HTTP-accessible endpoint and write them to InfluxDB Cloud, do the following in your Flux script:

  1. Import the experimental/prometheus package.
  2. Use prometheus.scrape() and provide the URL to scrape metrics from.
  3. Use to() and specify the InfluxDB Cloud bucket to write the scraped metrics to.
Example Flux script
import "experimental/prometheus"

prometheus.scrape(url: "http://example.com/metrics")
    |> to(bucket: "example-bucket")
  1. (Optional) To scrape Prometheus metrics at regular intervals using Flux, add your Flux scraping script as an InfluxDB task.

New in InfluxDB 3.5

Key enhancements in InfluxDB 3.5 and the InfluxDB 3 Explorer 1.3.

See the Blog Post

InfluxDB 3.5 is now available for both Core and Enterprise, introducing custom plugin repository support, enhanced operational visibility with queryable CLI parameters and manual node management, stronger security controls, and general performance improvements.

InfluxDB 3 Explorer 1.3 brings powerful new capabilities including Dashboards (beta) for saving and organizing your favorite queries, and cache querying for instant access to Last Value and Distinct Value caches—making Explorer a more comprehensive workspace for time series monitoring and analysis.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On November 3, 2025, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
