  1. 请问集群是从哪个低版本升级上来的,还是新建的?
    2 . 是否尝试过使用不同浏览器导出?

麻烦截个 profiling 详情界面的图(在点开出现这个页面的前一个页面),应该会有报错信息

这个?

从5.0升级来的。。
再不同浏览器上也是会报错

现在还报错吗?如果还报错,对报错的 TiDB server 节点执行 curl 手工抓取一下试试看 wget http://{TiDBIP}:10080/debug/pprof/profile?seconds=10

profile5 (136.3 KB) profile4 (108.0 KB)

麻烦反馈下 tikv 运行脚本 run_tikv.sh 内容,默认路径在 {Deploy Dir}/scripts 下面

从脚本内容看是正常的,和之前发现的一个问题不一样。你这边是只在这两个 tidb 节点有这个现象吗?在 dashboard 上点击性能分析后, tidb 的日志中有无异常信息,如果有的话麻烦提供下 tidb 的日志

这个问题正在内部分析,对 TiDB 集群正常使用应该没有影响,后面有结果会在该帖回复,辛苦了:pray:

执行的时候其中两个节点会报错,不一定是这两个

这个问题已经内部复现,计划在 5.0.4 修复,修复 issue 信息:https://github.com/pingcap/tidb-dashboard/pull/944
