In case there is a need to check haproxy logs for a loadbalancer and investigate requests, it can be done the following way:

  1. Find the loadbalancer you need

# openstack loadbalancer list | grep <loadbalancer_uuid/name>

  1. Find the amphora for the loadbalancer/s 

# openstack loadbalancer amphora list --loadbalancer <loadbalancer_uuid>
+--------------------------------------+--------------------------------------+-----------+------------+---------------+--------------+
| id                                   | loadbalancer_id                      | status    | role       | lb_network_ip | ha_ip        |
+--------------------------------------+--------------------------------------+-----------+------------+---------------+--------------+
| 477b4499-f51d-465f-af53-4a2af8fbdbec | 9d6ee355-fe8d-4102-9eed-dfb28e73fbaa | ALLOCATED | STANDALONE | 10.197.115.49 | 10.30.10.144 |
+--------------------------------------+--------------------------------------+-----------+------------+---------------+--------------+

  1. Login to the amphora with ssh key (should be possible from any cluster node):

# ssh ubuntu@10.197.115.49 -i /etc/kolla/octavia/ssh/amphora_ssh_key

  1. Check haproxy.log which contains log for the loadbalancer

root@amphora-477b4499-f51d-465f-af53-4a2af8fbdbec:~# less /var/log/haproxy.log
