Кто еще не видел эти замечательные однострочные команды:
# New processes with arguments,
dtrace -n 'proc:::exec-success { trace(curpsinfo->pr_psargs); }'
# Files opened by process,
dtrace -n 'syscall::open*:entry { printf("%s %s",execname,copyinstr(arg0)); }'
# Syscall count by program,
dtrace -n 'syscall:::entry { @num[execname] = count(); }'
# Syscall count by syscall,
dtrace -n 'syscall:::entry { @num[probefunc] = count(); }'
# Syscall count by process,
dtrace -n 'syscall:::entry { @num[pid,execname] = count(); }'
# Read bytes by process,
dtrace -n 'sysinfo:::readch { @bytes[execname] = sum(arg0); }'
# Write bytes by process,
dtrace -n 'sysinfo:::writech { @bytes[execname] = sum(arg0); }'
# Read size distribution by process,
dtrace -n 'sysinfo:::readch { @dist[execname] = quantize(arg0); }'
# Write size distribution by process,
dtrace -n 'sysinfo:::writech { @dist[execname] = quantize(arg0); }'
# Disk size by process,
dtrace -n 'io:::start { printf("%d %s %d",pid,execname,args[0]->b_bcount); }'
# Pages paged in by process,
dtrace -n 'vminfo:::pgpgin { @pg[execname] = sum(arg0); }'
# Minor faults by process,
dtrace -n 'vminfo:::as_fault { @mem[execname] = sum(arg0); }'
