Overhead when enabling debug?

[mex]

hi agentzh, 


your points are valid, but i talk about heisenbugs and the ability
to monitor a certain ip; you know, theres WTF??? - errors :)

please note, on the infrastructure i talk about we have usually 
debug-logs disabled, and the bottleneck is usually the app-servers.


but thanx for your answer, i'll invest some time and check your toolchains,
especially systemtap. is systemtap included in openresty? looks like the 
perfect tool to create some nagios-plugins upon. 




regards, 


mex
