Finding busy disks with iostat and awk

So you want to find busy disks in solaris? Maybe you want a quick iostat summary? Need an easier way to find slow disks? Getting percent busy info from iostat is easy with awk. Usually any disk with %busy greater than 0 (some people prefer >= 2) is a sign of a slow disk.


iostat -xcn|awk '$10 > 0{ print $10"%" " - " $11 }'


Or perhaps you want to see how many disks are considered 'slow' in your system:


echo `iostat -xcn|awk '$10 > 0{ print $10"%" " - " $11 }'|wc -l` out of `iostat -xcn|wc -l`
