The AuditActivity_Proxy logs are filled with entries: Command=Get session;Result=200;ResultText=Success

According to article "Overview of Qlik Sense logs when one User initiates a Session ID by opening an application in the Hub"

Usually the AuditActivity_Proxy log is related to when a user gets a Session ID. The web socket connection is opened right after it.

Command=Get session;Result=200;ResultText=Success  fe87b122-8979-45d4-9c37-3c39ce704045

However, there could  be a situation where the logs show  multiple entries of session ID 0 as below

Command=Get session;Result=200;ResultText=Success 0 0 0 

This log entry is not normal, the frequency can only be controlled by identifying why are there so many sessions trying to get established ?

Usually as below when a valid session gets established it is followed by the app access web Socket connection.

When session id is showing 0, this indicates to an automated task polling / connecting to the proxy server without any action, in most situations this is a NLB load balancer poll doing server heartbeat check with the wrong URL, server IP or host name.

The NLB polling to monitor availability shows that it is configured with wrong URL such as  https://<serverIP>/ 

The heartbeat check URL should be be changed to: https://server.domain.com/engine/healthcheck/ and NOT https://<serverIP>/

Issue in logs: Why are there so many calls with session ids = 0 ?
