Description

Target count: 8k

Strategy: OSD map is core data structure which is often exchanged between Ceph services. Efficient API calls allow to retrieve the list of OSDs. OSD metadata might require extra calls.

From Pawsey:
  • "osd view takes 40+secs to populate the first page. During this period there is no indication that it is working at all - when you do get the display the UI is very slow no other link works - like the data is still be loaded in the background and consuming cycles. Firefox issues a pop up stating that page is slowing the browser down! I had to close the tab and relogin"
  • "osd view - refreshes every time you enter this menu option - each time there is a 40+sec lag"
