Balancing Type
Least Connection with persistence
As it is a stateful application, the balancing method must be defined as Least Connection, in order to preserve the states of sessions and open connections with the various components of senhasegura.
Monitoring
Regarding monitoring, senhasegura requires a combination of healthchecks on the TCP ports of each of the proxies plus checks on the application control URL.
Web Application Monitoring - HTTPS 443
The monitoring of the web application can be done via GET requests in the endpoint /flow/orbit/mntr. Response codes should be interpreted as fallows:
- HTTP 200: Application is enabled and available for operation
- HTTP 403: Application is enabled but unavailable for user operation
- HTTP 451: Activation license is expired
- HTTP 503: Application is disabled
Monitorinf of access proxies
In addition to maintaining persistence in the connections, it is mandatory to enable X-Forwarded-For (XFF) in balancer, in order to guarantee the consistency of data of the application reports.
Finally, it is necessary to import into the balancer (HTTPS proxy), the same digital certificate installed in the application.
