As far as I'm aware, OneAgent should report on network drives and report on them as mount points. The AppMon Host agent which is running on the host, does show all drives (10 in total, 7 local and 3 network file shares), yet the OneAgent doesn't report on the 3 network drives at all, I only see the 7 local mount points.
This is happening on a Linux host, but I see the same thing on a Windows host. On the Windows host, the 'dtuser' is part of the Performance Monitoring Users group on Windows. I have to admit that on the Windows host, there is a mapped drive that shows in Explorer but not as a drive under Disk Management, so I understand that it won't show in this case.
Is there a setting I'm missing perhaps?
I never created a product idea (RFE) for this, since the client who queried this, opted to simply monitor the host from which the directories are shared, instead of monitoring this from the client-side perspective, meaning the host where the mapped drives are configured.
It is better to monitor it from the server-side (where the shares are sitting) as it gives you all the metrics for disks, whereas the client-side would likely only give you free space/total space metrics only.
