Hi All,
we've set up ELK in our environment and its really a nice tool to check real time logs. Thanks for that.
but i really interested to know about.
1. is the server can collect all the logs from client and also stores it inside or it just creates a reference of log file.

There's no automatic way to restrict the number of indices. But you can use a tool like [Curator](https://github.com/elastic/curator) to automatically delete old indices based on a variety of criteria.
Or you can manually delete them.

Yep, if you delete older indices, the documents in those indices will no longer be available. So you won't see them in your dashboard.
It's fairly common for people to have a "retention period" of a week, a month, six months etc and then delete after that.

X-Pack is a commercial feature. Parts of it are free, and parts of it are higher subscription tiers that are paid. See [https://www.elastic.co/subscriptions](https://www.elastic.co/subscriptions) for more information, but authentication and role-based access control is under gold. If you like, you can go to that subscriptions page and start a free platinum trial to see if it's going to provide what you want. Also, our [Elastic Cloud offering](https://www.elastic.co/cloud) is a cloud service which includes the authentication and role-based access control features of X-Pack (for \<64GB RAM users) and also has a free trial.
You can have a look at [https://www.elastic.co/cloud/as-a-service/subscriptions](https://www.elastic.co/cloud/as-a-service/subscriptions) for what's offered there.
