Beamium collect metrics from HTTP endpoints like http://127.0.0.1/metrics and supports Prometheus and Warp10/Sensision format. Once scraped, Beamium can filter and forward data to a Warp10 Time Series platform. While acquiring metrics, Beamium uses DFO (Disk Fail Over) to prevent metrics loss due to eventual network issues or unavailable service.
Beamium is written in Rust to ensure efficiency, a very low footprint and deterministic performances.
Beamium key points:
- Simple: Beamium is a single binary that does one thing : scraping then pushing.
- Integration: Beamium fetch Prometheus metrics and so benefits from a large community.
- Reliable: Beamium handle network failure. Never loose data. We guarantee void proof graph ;)
- Versatile: Beamium can also scrape metrics from a directory.
- Powerful: Beamium is able to filter metrics and send them to multiple Warp10 platforms.
Scraper (optionals) will collect metrics from defined endpoints. They will store them into the source_dir. Beamium will read files inside source_dir, and will fan out them according to the provided selector into sink_dir. Finaly Beamium will push files from the sink_dir to the defined sinks.
The pipeline can be describe this way :
HTTP /metrics endpoint --scrape--> source_dir --route--> sink_dir --forward--> warp10
It also means that given your need, you could produce metrics directly to source/sink directory, example :
$ TS=`date +%s` && echo $TS"000000// metrics{} T" >> /opt/beamium/data/sources/prefix-$TS.metrics
Beamium is currently under development.
We provide deb packages for Beamium!
sudo apt-get install apt-transport-https
sudo lsb_release -a | grep Codename | awk '{print "deb https://last-public-ovh-metrics.snap.mirrors.ovh.net/debian/ " $2 " main"}' >> /etc/apt/sources.list.d/beamium.list
curl https://last-public-ovh-metrics.snap.mirrors.ovh.net/pub.key | sudo apt-key add -
sudo apt-get update
sudo apt-get install beamium
Beamium is pretty easy to build.
- Clone the repository
- Setup a minimal working config (see below)
- Install rust compile tools with
curl https://sh.rustup.rs -sSf | sh - Then
source ~/.cargo/env - Build with
cargo build - Finally, run
cargo run
If you have already rust:
cargo install --git https://github.com/ovh/beamium
Beamium come with a sample config file. Simply copy the sample to config.yaml, replace WARP10_ENDPOINT and WARP10_TOKEN, launch Beamiun and you are ready to go!
Config is composed of four parts:
Beamium can have none to many Prometheus or Warp10/Sensision endpoints. A scraper is defined as follow:

format: prometheus # Polling format (Optional, default: prometheus, value: [prometheus, sensision])
labels: # Labels definitions (Optional)
label_name: label_value # Label definition (Required)
filtered_labels: # filtered labels (optional)
- jobid # key label which is removed (required)
metrics: # filter fetched metrics (optional)
- node.* # regex used to select metrics (required)
