Open Stack

Hi Grant,

in case of Octavia, when you create healthmonitor with parameters of 
monitoring:

$ openstack loadbalancer healthmonitor create
usage: openstack loadbalancer healthmonitor create [-h]
                                                    [-f 
{json,shell,table,value,yaml}]
                                                    [-c COLUMN]
[--max-width <integer>]
[--fit-width]
[--print-empty]
[--noindent]
[--prefix PREFIX]
                                                    [--name <name>] --delay
<delay>
[--expected-codes <codes>]
[--http_method {GET,POST,DELETE,PUT,HEAD,OPTIONS,PATCH,CONNECT,TRACE}]
--timeout <timeout>
--max-retries <max_retries>
[--url-path <url_path>]
                                                    --type
{PING,HTTP,TCP,HTTPS,TLS-HELLO}
[--max-retries-down <max_retries_down>]
[--enable | --disable]
<pool>

Octavia pushes these parameters to haproxy config on Amphorae agent 
(/var/lib/octavia/<pool id>/haproxy.cfg) like this:

backend f30f2586-a387-40f4-a7b7-9718aebf49d4
     mode tcp
     balance roundrobin
     timeout check 1s
     server 26ae7b5c-4ec4-4bb3-ba21-6c8bccd9cdf8 10.1.4.11:80 weight 1 
check inter 5s fall 3 rise 3
     server 611a645e-9b47-40cd-a26a-b0b2a6348959 10.1.4.14:80 weight 1 
check inter 5s fall 3 rise 3

so, if you guess it's a problem with backend servers, you can play with 
HealthMonitor parameters in order to set appropriate timeouts for 
backend servers in this pool.
