A prometheus exporter that scrapes remote data or local files and converts them to prometheus metrics. It is similar to json_exporter, but adds the possibility to transform the data before metrics are extracted, and is not limited to only support JSON data.
A docker image is built as part of this repository. Find the published versions here
cargo test
cargo run -- --config examples/config.yaml
Now you can use curl to get the metrics:
curl http://localhost:9090/metrics
data-exporter is configured via a configuration file in YAML format (see this example), and via command-line flags.
Run the help command to get all available flags
data-exporter --help
In the configuration file all scraped metrics are configured.
