Thank you for your response AbhishekIlindra,

I used the /users/online rest api call in the custom component. Based on the component result, i just customized the output. 

From the rest api result set returning all other information like last_visit_time, id and etc. But it's not return the "login" and which contain the username, and it returns empty string. 

Thank you so much TariqHussain,

I just understand the issue, and the query which you have suggested is working fine. Also i need to display the newest community member, i have used 

http://<communityurl>/restapi/vc/users/registered

But this query also returning the empty login name. So here could you suggest, any alternate query we can use, or any additional parameter we can use, or we need to write any additional condition to restrict the empty results? Please suggest.
