Doc Text:
.cephfs-top limitation is increased for more client loading Previously, due to a limitation in the `cephfs-top` utility, only less than 100 clients were loaded at a time, which could not be scrolled and also hung if more clients were loaded. With this release, `cephfs-top` users can scroll vertically, as well as, horizontally. This enables `cephfs-top` to load nearly 10,000 clients. The users can scroll the loaded clients, and view them on the screen.

Description Jos Collin 2022-10-31 09:43:47 UTC
+++ This bug was initially created as a clone of Bug #2073273 +++

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.
