ioping - Storage Latency benchmark


A tool to monitor I/O latency in real time. It shows disk latency in the same way as ping shows network latency.

With ioping benchmark you can measure the latency of the storage I/O subsystem in your Kubernetes cluster.

Mode of operation

Kubestone generates a Kubernetes Job from each ioping CR.

Volume defines the volume to use for benchmarking. Volume.VolumeSource provides way to mount already existing PVCs, HostPath, EmptyDir (and others) to the benchmark.

When Volume.PersistentVolumeClaimSpec is defined (and Volume.VolumeSource.PersistentVolumeClaim.ClaimName set to 'GENERATED') a new PVC will be created for the benchmark. Note: The created volume is not freed up or removed after the benchmark run.

Example configuration

You can find configuration example in the GitHub repository.

Sample benchmark

To run a sample benchmark with EmptyDir, the following command can be used:

$ kubectl create --namespace kubestone -f

Please refer to the quickstart guide for further details.

ioping configuration

The complete documentation of ioping CR can be found in the API Docs.
