using TOPAS

Hi,

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?

Thanks,
