syscallbyproc.d
syscallbyproc.d(1m) USER COMMANDS syscallbyproc.d(1m)NAME
syscallbyproc.d - syscalls by process name. Uses DTrace.
SYNOPSIS
syscallbyproc.d
DESCRIPTION
syscallbyproc.d is a DTrace OneLiner to a report of the number of system calls made by process name.
This is useful to identify which process is causing the most system calls.
Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt in the DTraceToolkit contain this as a oneliner that can be cut-n-paste to run.
Since this uses DTrace, only users with root privileges can run this command.
EXAMPLES
This samples until Ctrl-C is hit.
# syscallbyproc.d
FIELDS
first field
This is the process name. There may be several PIDs that have the same process name, for example with numerous instances of "bash".
The value reported will be the sum of them all.
second field
This is the count, the number of system calls made.
DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
EXIT
syscallbyproc.d will sample until Ctrl-C is hit.
