[lttng-dev] 回复:Re: 回复:Re: Pros and Cons of LTTng

[杨海]

Hi


Thanks for quick response. 
LTTng is really impressive on performance，especially under heavy workload. When using it on critical machines，stability is also essential. 
I wonder how LTTng is commercialized and any products or OS distributions already enabled it. 
I took a look at lttng-modules bug list，there are a few kernel oops years ago and got resolved. May I say it is very stable or it has not been fully tested? 


regards
Hai

 Hi,

> As to LD_PRELOAD, it is also used for privilege escalation. Will it be regarded as vulnerability and forbidden on some Linux systems?

It could yes.
In that case you will be limited to the syscalls interface for the libc
observability unless you instrument it and distribute it.

Cheers.
