[dtrace-discuss] Combining Two providers

[Chip Bennett]

Hi Neelam,

Are you asking if you can have one D script that enables lockstat probes 
and vminfo probes at the same time?  Absolutely.  I would think you 
would have one set of probe clauses to trace paging activity and another 
set to trace lock activity.  However, since you'll likely be dealing 
with multiple threads causing enabled probes to fire simultaneously, 
make sure you use thread local variables appropriately.
