iotop on High Sierra

I seem to have issues with iotop on High Sierra, googling it I find no useful information. The output is garbled and almost unusable. I have SIP disabled for dtrace (I know "I'm not suppose to do that", but it worked fine on previous version of OS X, i.e. > crsutil enable --without dtrace). Example output: 2017 Oct 16 11:46:25, load: 2.45, disk_r: 2520 KB, disk_w: 0 KB UID PID PPID CMD DEVICE MAJ MIN D BYTES 0 182 1 mobileassetd ?? 1 4 R 4096 0 653 340 scep_daemon ?? 1 4 R 81920 0 153 1 sandboxd ?? 1 4 R 167936 0 304 1 mds_stores ?? 1 4 R 831488 120215604 3950 1 IDECacheDeleteAp ?? 1 4 R 1490944 0 0 0 ?? 1 4 1495040 0 0 0 ?? 1 3 8474624 dtrace: 3060 dynamic variable drops with non-empty dirty list dtrace: 2000 dynamic variable drops with non-empty dirty list dtrace: 192 dynamic variable drops with non-empty dirty list The issues as I see them are the dtrace: xxx dynamic drops, missing data (there are processes missing) and last the fact that the indentation is messed up. Googling does not bring me closer to the answer. The only reasonable connection I can find is that the buffer is overflowing (due to disk activity) and to change the buffer policy with the following: #pragma D option bufpolicy=ring But since iotop is already compiled I have a hard time doing any changes to it. Or is the osx / apple version of iotop available somewhere so I can rebuild it with necessary changes? And just for completeness, I built the gnu version of iotop but it wouldn't run and complains that my linux kernel is too old ^^ Anyhow, found this as well: https://apple.stackexchange.com/a/208185/173331 , and the answer details that Apple is doing some funny shit and hiding processes from dtrace, and in effect I might not solve the "all processes are not showing up" issue. (apparently I don't have enough reputation on apple.stackexchange.com to create an "iotop"-tag)
