一、组网图

二、问题描述

已经配置了自动性能统计后，点击GUI界面中-性能统计-历史性能数据 时，历史性能数据不显示或显示不全，不能正常导出数据。

三、过程分析

性能统计下文件过多，导致加载历史性能数据时，底层 message 中出现 call trace 堆栈的问题；且存储双端的/odsp/log/local/perf目录下历史的.tgz文件过多，导致前端页面信息加载不全。

四、解决方法

建议定期备份并清理历史的 .tgz 文件，释放目录空间。（该问题在V1.5.12T04X版本上已经解决）

1、登录两端控制器的 /odsp/log/local/perf 目录，将双控 perf 文件夹完整备份至本地：

2、拷贝完毕后， 使用 SSH 或串口登录SP1 控制器，执行 ll /odsp/log/local/perf/*.tgz 列出并确认是需要删除的 *.tgz 文件。

3、检查无误后，在SP1 控制器中，执行 rm -rf /odsp/log/local/perf/*.tgz 删除历史性能数据的 tgz 包。

rm -rf /odsp/log/local/perf/*.tgz

4、登录SP2 ，重复 2 、 3 的操作。

5、依次在SP1 、SP2 控执行 sync 命令同步。

6、登录存储 GUI 界面，点击设备 ---> 重新扫描，并耐心等待扫描完成。

7 、重新加载“历史性能日志”，此时数据恢复正常加载。

五、风险提示

底层需要执行rm -rf命令操作，请谨慎操作！！
