Hi,
Iβm planning to extend spdk_top functionality in upcoming weeks. Iβve been seeing that
some of you are already using this tool and therefore Iβd 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 π

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,
In below screen you have idle/busy stats per thread (Threads tab). We want to add similar
stats per poller in Pollers tab.

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.

got it, is there some RPC to get initiator drivers (e.g nvme
pci/rdma/tcp) idle/busy cycles or
the initiator sw architecture (poll groups and such) is not supported
for that matter?
7:46 p.m.
There are 3 RPC calls that are used by spdk_top, which provide stats:
thread_get_stats
thread_get_pollers
framework_get_reactors
They provide stats on pollers and threads associated with poll groups as well. More
detailed stats regarding poll groups are planned to be implemented.
Regards,
Maciek
