how to check if peering truly works (1 reply)

I'm checking the contents of the app_api table on both HAproxy
instances, and they are for the most part the same, but a few entries
are different - same key uses different server_id values on different
HAproxy instances. I thought peering was supposed to get rid of
inconsistencies like this.

How do I check if peering is actually enabled and passing data between
proxies? I'm looking at the commands I could send to the stats socket,
and there doesn't seem to be anything related to peering there.
