审计日志

为了记录 HwameiStor 集群系统的使用和操作历史信息，HwameiStor 提供了系统审计日志。该审计日志具有 HwameiStor 系统语义，易于用户查阅、解析。 审计日志针对 HwameiStor 系统中的每类资源，记录其使用操作信息。该资源包括：Cluster、Node、StoragePool、Volume，等等。

使用方式

审计日志通过 CRD 的方式存入系统中，为每一个资源创建一个 CR 来记录其操作历史。该 CRD 如下：

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

例如，我们可以看看数据卷的审计信息：

apiVersion: hwameistor.io/v1alpha1
kind: Event
