System Audit

System Audit

It's important to record the information about the system operation history. HwameiStor provides a feature of audit to record the operations on all the system resources, including Cluster, Node, StoragePool, Volume, etc...

The audit information is easier for user to understant and parse for various purposes.

How to use

HwameiStor designs a new CRD for every resource as below:

apiVersion: hwameistor.io/v1alpha1
kind: Event
  name: 
spec:
  resourceType: <Cluster | Node | StoragePool | Volume>
  resourceName:
  records:
  - action:
    actionContent: # in JSON format
    time:
    state:
    stateContent: # in JSON format

For instance, let's look at audit information of a volume:

apiVersion: hwameistor.io/v1alpha1
kind: Event
metadata:
  creationTimestamp: "2023-08-08T15:52:55Z"
  generation: 5
  name: volume-pvc-34e3b086-2d95-4980-beb6-e175fd79a847
  resourceVersion: "10221888"
  uid: d3ebaffb-eddb-4c84-93be-efff350688af
spec:
  resourceType: Volume
  resourceName: pvc-34e3b086-2d95-4980-beb6-e175fd79a847
  records:
  - action: Create
