Export counters for packets and connections in trex

[Robert Blomberg]

Hi guys!

Is it possible to extract counters in trex for RX - packets, TX-packets, etc in Stateful-mode?

We want to use trex, but don't want to poll counters from the DUT, but from Trex to verify that the values on the DUT and trex are the same so we could measure accuracy.

Hi,

TRex stateful sends stats by ZMQ publisher (port 4500 by default):

https://trex-tgn.cisco.com/trex/doc/cp_docs/api/json_fields.html

If the server was started by trex_daemon_server, it is possible also to query the results by Python JSON-RPC commands from the server, or by usual Python API from trex-client.

Thanks,

Yaroslav.

Simple example here

https://github.com/cisco-system-traffic-generator/trex-core/blob/master/scripts/automation/trex_control_plane/stf/examples/stf_tcp.py

There is python API documentation in the main page
