红帽全球峰会3.14.3. 查看收集的对象垃圾回收数
您可以使用性能转储中的 gc_retire_object 参数，查看 Ceph 对象网关启动的对象数量。
可监控这个计数器，以确定该 Ceph 对象网关的特定时间段内对象数量之间的 delta，例如，每周、每天或每小时收集的对象数平均数量。这可用于确定每个 Ceph 对象网关的垃圾收集进度。
套接字文件位于 /var/run/ceph 目录中。
先决条件
- 安装了 Ceph 对象网关运行的 Red Hat Ceph Storage 集群。
- 对存储集群中所有节点的根级别访问权限。
-
Ceph 监控器上安装的
ceph-common软件包。
流程
使用
gc_retire_object计数器的grep访问性能计数器数据：语法
ceph --admin-daemon PATH_TO_SOCKET_FILE perf dump | grep gc_retire_object
