I’ve been seeing that some of you are already using this tool and therefore I’d to hear from you what new features would you like to see in the tool. Feel free to send some ideas here or join next euro friendly community meeting to discuss it


    You mentioned in the trello doc having idle/busy indicator for each
    poller -- I see we have it with 20.07 - am I wrong (below)?

    Is there intention to expose the spdk_top info via rpc so it can be scripted?

Hi Or,

There is no intention to have spdk_top expose data via RPC.  Scripts can submit RPCs directly to the application under test to gather information and then post-process it any way it wants.
