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.

Maciek

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?

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.

Maciek

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?

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.
