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.
