It doesn't matter whether you're on EL5 or EL6, "1" in top should show the per-cpu stats like this: top - 08:42:00 up 4 days, 20:51, 1 user, load average: 0.00, 0.01, 0.05 Tasks: 118 total, 1 running, 117 sleeping, 0 stopped, 0 zombie Cpu0 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu1 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu2 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu3 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1880072k total, 1159908k used, 720164k free, 195840k buffers Swap: 1048572k total, 0k used, 1048572k free, 606672k cached It's not even as though the per-cpu information comes from a different place: top gets both summary and the per-cpu data from /proc/stat. Even if you only have one CPU you'd still see a "Cpu0" line instead of "Cpu(s). The only way I can see to prevent top from displaying per-cpu information is to prevent it displaying any cpu information at all: try hitting "t" -- that will take away the Tasks and Cpu lines. It's possible that the Task area (t flag) is off by default: it can be set in either ~/.toprc or /etc/toprc. If it's not and you still don't have per-cpu data then something is seriously amiss. Check /proc/stat to make sure you do have per-cpu lines, check "rpm -qf $(type -p top)" to make sure the top you're running really is the one in the procps rpm and "rpm -V procps" to make sure procps isn't damaged. And then check for rootkits :) jch </div></div>
