Now that I got such a great response on the top, how about disk activity? I have been using the iostat -xdn and the Veritas Volume Manager vxstat -d -i 5 -c 6. Each gives good data but I am looking for something to run at the vt100 terminal similar to the top tools that operators, dba's, etc. could look at to get an idea if there is a problem with i/o.
