Uses Linux SystemTap (non-debuginfo). .SH SYNOPSIS .B syscallbypid-nd.stp .SH DESCRIPTION This traces syscalls system-wide, and produces a summary report showing their counts by process ID, process name, and syscall types. .SH REQUIREMENTS SystemTap. .SH EXAMPLES .TP Count and summarize syscalls: # .B syscallbypid-nd.stp .SH FIELDS .TP PID Process ID. .TP CMD Process name. .TP SYSCALL System call name. .TP COUNT Number of syscalls issued during tracing. .SH OVERHEAD This uses in-kernel summaries to reduce overheads, so the overhead should be low (much lower than the current strace(1) implementation, for example). Test before use to confirm. .SH SOURCE This is from the SystemTap lwtools collection. .IP https://github.com/brendangregg/systemtap-lwtools .PP Also look under the examples directory for a text file containing example usage, output, and commentary for this tool. .SH OS Linux .SH STABILITY Unstable - in development. .SH AUTHOR Brendan Gregg .SH SEE ALSO strace(1)
