Using uvmhist without ddb?

2013-02-21 Thread Brian Buhrow 
Hello.  I'm working on an issue with NetBSD-5 that may involve a
problem with error paths in uvm.  I'd like to  use the uvmhist facilities
in NetBSD to see if I can help track the issue down.  However, the machine
on which I'm doing this work doesn't support the convenient use of ddb(4).
Is there a way to get  uvm to print its statistical history without having
to drop the machine into ddb?
-thanks

Look at UVMHIST_PRINT.

 Look at UVMHIST_PRINT.

or vmstat -U or vmstat -u history
