I have databases delpoyed as StatefullSet on my kubernetes cluster, i would like to know how can i make alerts (send email) when Persistent Volumes are 80% full ?

P.S: This k8s cluster is deployed using Rancher v2.4

Any help would be really appreciated!

Thank you in advance!

Have you already looked at Kubernetes mixin alerts KubePersistentVolumeFillingUp in https://monitoring.mixins.dev/kubernetes ?

CodePudding user response：

You will need to monitor your volumes from Prometheus, the link above from Manoj is a good start or visit kubepersistentvolumefillingup

After prometheus is happy, you can configure alert manager to generate email alerts.

Good luck.

There is a helm chart to get you started. kube-prometheus
