We are trying to move away from using SCOM in some areas. One of the things that they did was they had 4 different charts or a group of servers: 4 Day CPU %, 14 Day Disk Free Space %, 14 Day Disk Idle %, and 14 Day Memory %. The 14 day is being changed to 7 days, but the only one I am having issues with is the Disk Idle. I can not find how chart/graph this for a group of servers. I thought that I may have to create a custom poller for this, but I am not sure how to do that since all the servers are Windows using WMI.
Any suggestions?
