----Original Message Follows---- From: Mike Smith <mike@smith.net.au> >You can add "counters" with sysctl. You can also add read/write >variables of any type. You can add them dynamically at runtime? How do you know which counters are available at a given time? >One thing that puzzles me; you say "userland processes can add their >own". What value would that have, since there'd be nothing in the >kernel that would do anything with such an object? But if a user mode server can mantain performance statistics there, then some performance monitoring tool would be able to query that counters and allow some analysis. It can be done by other means, but I think it can be usefull having it all together using a unique system call.
