Most interesting statistics should be available through systat(1), iostat(8) and vmstat(8). There are other stats that are recorded in the devstat(9) system, but that aren't displayed in the stats-display utilities. (like the number of ordered tags, number of outstanding transactions) There's a program on my ftp site that will dump out the contents of all the devstat(9) structures in the system: ftp://ftp.kdm.org/pub/FreeBSD/cam/ds.c If there are stats that aren't available that you'd like to see, let me know so I can keep them in mind for future enhancements. > In either case, CAM appears to be working very well on one of my big > machines, with an NCR and an AHA3940.
