Uses DTrace. +.SH SYNOPSIS +.B syscallbyproc.d +.SH 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 the root user or users with the +dtrace_kernel privilege can run this command. +.SH OS +Any +.SH STABILITY +stable - needs the syscall provider. +.SH EXAMPLES +.TP +This samples until Ctrl\-C is hit. +# +.B syscallbyproc.d +.PP +.SH FIELDS +.TP +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. +.TP +second field +This is the count, the number of system calls made. +.PP +.SH DOCUMENTATION +See the DTraceToolkit for further documentation under the +Docs directory.
