I am trying to make the replica of activity monitor . there are tabs system memory and disk activity Where it gives information about hard disk read/write and in system memory it provides information about Free memory ,wired , active, inactive , used memory ,VM size etc. I've tried a lot to get this information but not able to get all. It'll be better if you can put some focus on it There aren't any Cocoa APIs for this — you'll need lower-level Unix APIs. This has been discussed on other lists like darwin-userlevel. There is at least one open-source Apple component that uses these APIs that you can look at for reference, but I don't remember exactly what it is. (It might be the 'top' tool.)
