Instructions

《NetWorker Vmware 集成指南“性能和可扩展性”部分概述了性能和可扩展性选项以及最佳实践，该指南可通过以下链接获得：https://www.dell.com/support/home/product-support/product/networker/docs

1.在 NetWorker 服务器上，创建输入文件（例如：vmperf）
2.使用以下详细信息填充输入文件： 
. type: save job; vm_name: VM_NAME
sh vm_name; job output; start time; end time; job log file
p
提醒：将 VM_NAME 替换为受影响虚拟机的名称。您可以从  mminfo -kot 输出中获取此信息。

3.使用作业查询和输入文件，我们可以收集有关作业开始和结束时间以及备份会话日志信息的详细信息。 
[root@nwserver ~]# jobquery -i vmperf
Current query set
                    end time: 1654567313;
                job log file: \
/nsr/logs/policy/Gold/VMware/353252-winclient01-2022-6-6-19-1-53.log;
                  job output: Backup completed successfully.;
                  start time: 1654567245;
                     vm_name: winclient01;
end time: 1654480913;
                job log file: \
/nsr/logs/policy/Gold/VMware/353027-winclient01-2022-6-5-19-1-53.log;
                  job output: Backup completed successfully.;
                  start time: 1654480845;
                     vm_name: winclient01;
end time: 1654394509;
                job log file: \
/nsr/logs/policy/Gold/VMware/352801-winclient01-2022-6-4-19-1-47.log;
                  job output: Backup completed successfully.;
                  start time: 1654394446;
                     vm_name: winclient01;
 
4.输出的时间在 UNIX 时间内，但可以使用以下内容进行转换：date -d@UNIX_TIME 
[root@nwserver ~]# date -d@1654394446
Sat Jun  4 19:00:46 PDT 2022
[root@nwserver ~]# date -d@1654394509
Sat Jun  4 19:01:49 PDT 2022
5.对于具有较长备份运行的备份，请查看作业日志文件，了解有关吞吐量的信息： 
[root@nwserver ~]# cat /nsr/logs/policy/Gold/VMware/352801-winclient01-2022-6-4-19-1-47.log | grep "DiskStats"
2022-06-05T02:01:48Z INFO:   [@(#) Build number: 95] DiskStats: Disk Label    |  Mode  | Bytes Moved |  Read Rate   |  Write Rate  |     Overhead  |   VDDK Wait   |   Total Time  | VM MORef  | VM Name

提醒：在备份时间比平常长的日期中，总写入速度低于其他备份会话中的平均写入速度。 

6.可通过运行以下命令来检查特定虚拟机的策略日志：
cat /nsr/policy/POLICY_NAME/WORKFLOW_NAME/*VM_NAME*.log | grep DiskStats 
[root@nwserver ~]# cat /nsr/logs/policy/Gold/VMware/*winclient01*.log | grep "DiskStats"
2022-06-05T02:01:48Z INFO:   [@(#) Build number: 95] DiskStats: Disk Label    |  Mode  | Bytes Moved |  Read Rate   |  Write Rate  |     Overhead  |   VDDK Wait   |   Total Time  | VM MORef  | VM Name

提醒：策略日志遵循 jobsdb 保留（默认值：72 小时）。jobsdb 窗口期过去后，将删除关联的策略日志和作业查询条目；但是，vProxy 设备会将虚拟机备份会话日志本地保留在 /opt/emc/vproxy/runtime/logs/recycle/vbackupd/ 下
