Pools stats showing NAN¶

Pool performance on busy pools showing NAN undefined (screenshot provided)

This is similar to the triaged bug https://tracker.ceph.com/issues/53591

I've also attached the json payload from the pool?stats=true call

Environment¶

• ceph version string:
• Platform (OS/distro/release):
• Cluster details (nodes, monitors, OSDs):
• Did it happen on a stable environment or after a migration/upgrade?:
• Browser used (e.g.: Version 86.0.4240.198 (Official Build) (64-bit)):

How reproducible¶

Steps:

1. Run a cluster under load (in my case rbd, 12,500 IOPS).

Actual results¶

See screenshot and json provided

Expected results¶

UI should show the same information that is available at the CLI

  io:
    client:   44 MiB/s rd, 13 MiB/s wr, 13.62k op/s rd, 3.07k op/s wr
