View the usage of K8s PV(PersistentVolume) and trigger an event (e.g., an event occurs when the PV usage exceeds 80%)

I want to monitor the usage of PV in Kubernetes and trigger an event when the usage exceeds a certain amount compared to the total usage. I would like to request the addition of this function.

    Hi! Sorry for the late reply. There is actually a feature flag that needs to be enabled based on this documentation:

    Now I understood, in the "Analyze Infrastructure" you have to search not for a host but directly for the "kubernetes persistent volume" or dimply for "kubernetes"

    So, all important PVC/PV metrics are present under Hosts.


    Infrastructure UI:

    The first way to find these metrics are going to the Infrastructure > Analyze Infrastructure UI. Here, you click on Hosts.

    Then, you can filter for Kubernetes Persistent Volume or Claim. And you'll see a bunch of different metrics available for free disk space, used disk percentage, and capacity.

    Dashboards:

    In the same way, you can add them to a dashboard.

    You select infrastructure & platforms, the relevant metric, and then filter for a specific PV/PVC.

    Alerting:

    You should also be able to create a Smart Alert with the same data.
