using TOPAS


I'm using topas to monitor CPU and Disk activity including paging space. Previously, I can see the percentage activity of the disk under column "BUSY%", now I can no longer view it (it's all zero), unless I will run IOSTAT 2 simultaneously. What would be the cause of this?

Press the "d" key. It toggles the disk usage display.

By default on AIX, the collection of disk io stats are disabled. This is to improve the peformance.If you need to enable this function

Run the following command

chdev -l sys0 -a iostat=true
You can check the attribute set using the following command

lsattr -E -l sys0 -a iostat
