  • Thread-topic: Switching Xenmon on and off

I'm using Xenmon to monitor Xen system performance, and all works fine. I run 
the latest Xen release 3.0.4, 64-bit. I assume that Xenmon does affect the 
performance of the system a bit, simply by collecting data etc, and I see that 
if it runs then the system performance slows down (a little bit). Now my 
question is what is the right way of actually stopping Xenmon completely? I 
switch it on by just running xenmon.py, and I kill the process to stop it. 
However, even after killing the process, I still see a bit of a performance 
slowdown, and I just want to be sure that this is the right way of switching 
off Xenmon? Does that leave anything running (in the background or elsewhere)? 
Also, are Xen trace buffers switched on and off on-the-fly when 
starting/stopping Xenmon?

Thanks,
Anna
