Prometheus exporter for fio benchmarks. Fio (Flexible I/O Tester) is a tool for storage performance benchmarking.
This is a fork from this version of fio_benchmark_exporter and the goal here is to parse json output instead of the terse output format so that it's easy to export all the metrics.
It's my first go-lang project so it's probably unoptimal and ugly code. Please submit PRs to improve the code.
go build .
A sample Dockerfile, docker-compose.yaml, kustomization.yaml and kubernetes manifests are also provided.
Running the exporter requires fio and the libaio development packages to be installed on the host.
./yafio_exporter <flags>
For a kubernetes deployment edit kustomization.yaml as needed (you will probably need to change the storageClass in resources/pvc.yaml) and apply the resources:
kustomize build | kubectl apply -f -
./yafio_exporter -h
$ ./yafio_exporter -h
Usage of ./yafio_exporter:
-flags string
flags passed to fio
-name string
Job name (default "benchmark")
-noExporter
Disables the prometheus endpoint
-port string
metrics tcp listen port (default "9996")
-preset string
Preset name (iops, latency or throughput)
-runtime string
Runtime (default "60")
-statusUpdateInterval string
metric update interval in seconds when statusUpdates enabled (default "6")
-testid string
