vmstat(1) tries very hard to fit everything in 80 columns. Unfortunately, it's been years since anyone had a machine where none of the columns overflowed. The recent addition of -h helps with the avm and fre columns, but on a busy system (e.g. a Varnish server on a busy web site), pretty much every single column will overflow. If you have disks with names longer than three letters, even the two header lines will be misaligned! Here's an example from a mostly idle machine: procs memory page disks f= aults cpu r b w avm fre flt re pi po fr sr ad0 ad1 ad2 ad3 ad10 ad12= in sy cs us sy id 2 1 0 193M 1015M 444 2 8 0 4862 0 0 0 0 0 0 0 = 348 1297 4704 1 7 92 Removing columns is not an acceptable solution (it would break too many existing scripts), so I'm afraid we're going to have to make the output wider than 80 columns, unless someone can come up with a better solution.
