Description Jos Collin 2022-04-08 06:08:47 UTC

Description of problem:

Based on the discussions in the BZ [1],

1. Make cephfs-top display scroll-able like top does. Enable Up/Down, PgUp/PgDn, Right/Left keys to display line-entries which are off the window. Zoom-in the cephfs-top display with 100+ clients (fill up the screen) to simulate this issue. At present, cephfs-top displays only the clients listed at the top (top-left) and there's no way to move down or sideways.

2. There is a related issue of cephfs-top shows blank screen when the number of clients exceeds 150 to 200 clients. Check and fix that too.

Version-Release number of selected component (if applicable):
RHCS 5.0z4

How reproducible:
Mount more number of clients (100 clients) than the screen could accommodate and run cephfs-top.

Steps to Reproduce:
Same as above.

Actual results:
Can't scroll and see the clients which are off the window and great number of clients shows blank screen.

Expected results:
cephfs-top display should be scroll-able for great number of clients like top(1) does.
cephfs-top should display the clients (no blank screen) for great number of clients.

We've agreed to put this in 5.3. The trackers are a bit of a mess, I don't recall if we have a separate upstream PR resolving this issue or if it's pending on https://github.com/ceph/ceph/pull/46072

We will be adding this feature as a separate PR.
