We have a server that is displaying high % disk time, often through out a day application that are server based become slow and unresponsive. We have pretty mush narrowed this down to a disk bottleneck that kicks in when Trend micro updates. However we have this on much older servers and dont have any problems.
Can anyone recommend any tools that can tell me what applications are causing the disk usage so that we can make sure nothing unusual is accessing the disks. The cpu usage is prety steady.
