Sometimes it is desirable to avoid sending health checks to servers at
exact intervals, for instance when many logical servers are located on
the same physical server. With the help of this parameter, it becomes
possible to add some randomness in the check interval between 0 and
+/- 50%. A value between 2 and 5 seems to show good results.

default_retries:
default: 3
type: int
description: |
Set the number of retries to perform on a server after a connection
failure. It is important to understand that this value applies to the
number of connection attempts, not full requests. When a connection
has effectively been established to a server, there will be no more
retry.
In order to avoid immediate reconnections to a server which is
restarting, a turn-around timer of 1 second is applied before a retry
occurs.

Services definition(s). Although the variable type is a string, this is
interpreted in the charm as yaml. To use multiple services within the
same haproxy instance, specify all of the variables (service_name,
service_host, service_port, service_options, server_options) with a "-"
before the first variable, service_name, as above. Service options is a
comma separated list, server options will be appended as a string to
the individual server lines for a given listen stanza.
