Hello @Abhishek Vastar (Accenture International Limited)

1. You can view the active number of connected clients to your Redis Cache from :-
   Azure portal -> Your Cache -> Monitoring -> Metrics -> ConnectedClients
   source: https://learn.microsoft.com/en-us/azure/azure-monitor/reference/supported-metrics/microsoft-cache-redis-metrics
2. If you are looking for the IP address (source IP) which are connecting to the Redis cache, you can enable connection auditing for your cache and review the output from there. In case if you are sending the logs to a log analytics workspace, you can use a KQL query to filter out the details of the client IPs.
   Sample KQL query that can be used :-

      ACRConnectedClientList
      | project TimeGenerated, ClientIp
   

   [Note: You may notice some internal Microsoft IP addresses, which are the private IPs used by Microsoft for Redis management and essential operations.]
