Hi Cephers,
I am building NFS GW for our test Ceph cluster based on Ceph Pacific
16.2.7.
I have to use manual installation, so my system doesn't have an
orchestrator enabled in the cluster.
I have 3 MDS, 6 OSD, 2 RadosGW and 2 NFS GW nodes.
All components including RadosGW dashboard works fine, but the NFS page
returns the "page not found" message and also additional notification:
"500 - Internal Server Error
The server encountered an unexpected condition which prevented it from
fulfilling the request."
Ceph-mgr logs show the next messages:

Could you please advise if it's possible to set up a dashboard for NFS
gateways?
Thank you in advance.
