Question on Zscaler Splunk integration

Hi Team,

We are using Zscaler in our environment and the logs are being sent to Splunk via NSS. during weekends where there is less traffic on the network, we are getting notified as there is no being logged in to the splunk system. In order to avoid this alert, we would like to configure some sort of heartbeat in the Zscaler system where Zscaler can create a dummy log entry that can be forwarded to the SIEM system. This will ensure that the message forwarding is working properly all time. Please let me know if Zscaler already has any feature like this or how we can achieve the same.
