New health check /send string required for OAP without any user/password authentication

Mamatha P-Oracle

After OAP standalone installation was upgraded to version 7.6 (Linux x86-64) of a clustered setup with 2 bi_server instances (bi_server1 and bi_server2) each health check from the loadbalancer generates a stack trace output in the bi_server<X>.out file. The most likely reason is that the content of /xmlpserver/services is no longer available with authentication.

Loadbalancer itself is also high available, every 10s the health check is executed 2 times. This floods the bi_server<X>.out file with Stack Traces and makes the log file unreadable for analysis.

The issue can be easily reproduced with curl, e.g. curl -k https://<OAP Managed Server>:<HTTPS Port>/xmlpserver/services. Also a web browser does the job as long as no user is logged in. A loadbalancer configuration isn't required.

We need ER to add new health check / send string which can be used without any user/password authentication in loadbalancer
