[dtrace-discuss] Using DTrace to monitor productions systems

[Dirk Volkmar]

Hi,

we are developing and operating an very critical application in the financial sector. Now our customer wants us to report performance data (roundtrip times of the messages routed). 
My idea is using dtrace  to measure the times with the pid provider catching the timestamps on entry of the in and out functions of the processes.
Now my questions ;-):

1) Is this an appropriate method to monitor [b]production [/b]system ?
2) Are there impacts on the [b]stability [/b]of the system ?
3) I can imagine that dtracing impacts the [b]performance[/b]. Has anybody 	experience how much it will impact?

Thanks for Your Comments 
Dirk
