fdb-exporter

Exports a subset of FoundationDB's "status json" command output as prometheus metrics using tally. It uses the FoundationDB client to connect to the cluster.

Configuration

This exporter is meant to be run in containers (it can be run a standlone service too, but no init scripts or systemd manifests are provided). The latest container image can be found at tigrisdata/fdb-exporter:main.

The configuration is done through the following environment variables:

• FDB_CLUSTER_FILE: the cluster file to connect to FoundationDB
• FDB_API_VERSION: the api version to use for the FoundationDB connection (default: 710)
• ENVIRONMENT: exposed directly as the environment tag in all metrics
• SERVICE: exposed directly as the service tag in all metrics
• FDB_VERSION: exposed directly as the version tag in all metrics
• FDB_CLUSTER_NAME: exposed directly as the cluster tag in all metrics
• FDB_EXPORTER_HTTP_LISTEN_ADDR: the address where the built-in web server will listen on and expose the metrics on /metrics url. The default is :8080

Building

To build a binary, simply run make. This will put an fdb-exporter binary in the current working directory. To make a container image, run docker build -t YOUR_ORG_HERE/fdb-exporter:YOUR_TAG_HERE ..

Testing

To run the tests, use the make test command. The tests will start the HTTP server of the interface, and will create the metrics based on bundled json files, and checks for the presence of the metrics.
