Doesn't top already run in Jail on -CURRENT? Thomas Moestl did this work a while back, exposing the necessary information to support most of our userland monitoring tools using sysctl rather than kvm: last pid: 32655; load averages: 0.05, 0.09, 0.07 up 7+14:52:51 09:50:01 2 processes: 1 running, 1 sleeping CPU states: 4.7% user, 0.0% nice, 2.3% system, 1.2% interrupt, 91.8% idle Mem: 61M Active, 21M Inact, 32M Wired, 6932K Cache, 22M Buf, 888K Free Swap: 261M Total, 52M Used, 209M Free, 20% Inuse PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 32652 root 96 0 1956K 1080K RUN 0:00 0.00% 0.00% top 32650 root 20 0 1448K 996K pause 0:00 0.00% 0.00% tcsh In general, new "features" for top go into the cross-platform vendor top code, but features to improve FreeBSD-specific information extraction go into our local tree. What exactly does -j do?
