Need critical user journey logs on Kibana to find out the errors what users get

Hi There,

I just wanted to tell you that i have deployed ELK stack on an EC2 instance and have routed the logs with the help of side car container deployment with application container. And it really worked and i can able to see the logs of the application on Kibana dashboard.

Now i have to get the critical user journey to be able to see in the form of logs like say transaction errors ( Finance project ). I'm expecting suggestions here to establish the mechanism.
And the second thing is to set up an authentication for the Kibana site and Elasticsearch as well. Would be appreciated any one can suggest me to set these two mechanisms.



Can i get replies here to the above post.
