.SH NAME

.SH DESCRIPTION
|
||
|
xcallsbypid.d reports the number of CPU cross calls by process name
|
||
|
and process ID. Cross calls occur when a CPU requests another CPU to
|
||
|
do work on it's behalf. A great number of these can be a burden
|
||
|
on the system.
|
||
|
|
||
|
Since this uses DTrace, only the root user or users with the
|
||
|
dtrace_kernel privilege can run this command.
