hi,高工,我知道你是中国人,在B站也关注了你,所以就用中文提问了:
最近有个项目要做tracing,第一时间想到了你的viztracer,效果不错;只是有一个没看明白:在使用vscode插件显示执行栈的时候,没有全部层层明显所有的调用栈:可以看到直接从main()到了__del__函数,是viztracer优化掉了吗?

viztracer能记录的entry数量是有限的,因为它不是一个summarize。这个就是viztracer的entry buffer overflow了所以把早期的东西扔掉了。你可以通过--tracer_entries调整buffer的size。vscode插件可以找到对应的设置去配置,cmdline直接给这个argument就行。
--tracer_entries
当然你的memory和disk都是有限的,不可能记录下无限时间的无限内容,perfetto的前端显示也有一定的限制(但是现在好像不小)。所以也可以考虑通过filter减少不重要的内容。
Sorry, something went wrong.
