Protocol + +
Proxy Protocol + + Proxy protocol preserves initial TCP connection information. Consult the Proxy Protocol guide for information on the differences between each option.
Algorithm + + Roundrobin assigns connections to each backend sequentially. Least connections choose the backend with the least number of current connections. Source uses the client's IPv4 address
Session Stickiness + + Route subsequent requests from a client to the same backend
SSL Settings
Common NameNeed help with SSL? - NodeBalancer Reference Guide

Replace Certificate
SSL Certificate
Private Key
Active Health Check
Health Check Type + + Active health checks proactively check the health of the backend nodes. 'TCP Connection' requires a successful TCP handshake. 'HTTP Valid Status' requires a 2xx or 3xx response from the backend node. 'HTTP Body Regex' uses a regex to match against an expected result body.
Check IntervalSeconds between health check probes
Check TimeoutSeconds to wait before considering the probe a failure. 1-30. Must be less than check interval.
Check AttemptsNumber of failed probes before taking a node out of rotation. 1-30
Check HTTP PathWhen check=http, the path to request
Expected HTTP BodyWhen check=http, a regex to match within the first 16KB of the response body
Passive Checks
EnabledEnable passive checks based on observing communication with backend nodes.
