Hi Ole, If that is correct, why I am not able to see the stats? ( I am waiting for 60 sec for getting the stats)

I am following instructions as specified in https://wiki.fd.io/view/VPP/Python_API. I am able to get other info as interface details etc. which uses dump and req/rep messages. vpp_papi.register_event_callback(papi_event_handler) does not call the callback function specified, when want_stats is called. In https://www.mail-archive.com/[email protected]/msg03819.html it is mentioned 1.) client -> want_stats -> vpp 2.) vpp -> want_stats_reply -> client (confirms subscription) 3.) vpp -> <various stats messages> -> client (when timer fires) in step 3.), client needs to read the shared memory queue in the vpp->client direction (or use the appropriate XXX_read() function). Note that stats take a few seconds to arrive (the test programs require 10-15 seconds of runtime to get some stats). But not sure where these read_from_shared_mem functions are. I assumed that want_stats will send the stats when enabled. Please guide on this. That’s correct, the Python language binding takes care of reading from shared memory. Sounds like you have done everything right. Cheers Ole Regards, Neha -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
