I've used SNMP (not WMI) to discover disks on our devices, so the disk sensors have tags like snmpdiskfreesensor, diskfree and snmp, but these sensors don't show up in the Top 10 Most/Least Available Disk Space dashboard widgets. This appears to be because the dashboard uses a different filter tag: diskspacesensor. Same goes for the equivalent top 10 map objects.
As a workaround, I've manually edited the underlying files (eg. top10listcontent.htm, Top10 Disks Least Free.htm) to include the diskfree tag. I'm guessing though that my changes will be lost on the next update. Is there a better solution for this?
Thanks - Simon
