Re: [Dprobes-list] DProbes logs to LTT 56 bytes

[Vara P. <pra...@us...>]

Hi Andrey,

I am glad to know that you are trying to use dprobes to solve your 
problem but most of the development has now moved from dprobes to 
systemtap. Systemtap is a feature which is much richer and easier to use 
than Dprobes.
You can find out all about systemtap at http://www.sourceware.org/systemtap

Please let me know if you have any questions about systemtap.

Thanks,
Vara Prasad
