4.5.6. DTrace of processes within a zone

[dd/ug] DTrace can be used to examine processes in zones. To do so, DTrace scripts can be

extended by the variable zonena me in order to e.g. only trace system calls of a zone

global# dtrace -n 'syscall:::/zonename==”sparse”/

{@[probefunc]=count()}'

or to measure the I/O of zones.

global# dtrace -n io:::start'{@[zonename] = count()}'

Starting with Solaris 10 11/06, DTrace can also be applied to processes within the own local zone.

The privileges dtrac e _pro c and dtrac e_use r need to be assigned to the zone

(zon e cfg: s et limi tpriv =defa u lt,d t race_ proc, d trac e _user ). Kernel tracing,

and the tracing of processes in the global zone, remains excluded. DTrace within a zone is of interest

especially for those use cases where a zone is used for software development or where the

administration of a zone was delegated. In this case, the local zone administrator is able to analyze

independent of the platforms administrator.
