Finally, from ELK itself, there is a very good demo for the Kibana dashboard, which shows various aspects of the stack, and shows the power and breadth of information it gives. It is available at http://demo.elastic.co.

This demo is spread across multiple dashboards based on Packetbeat, such as the MySQL dashboard, the MongoDB dashboard, the Web Transactions dashboard, the Thrift-RPC and PostgreSQL dashboard. It helps us understand many advanced searches and visualizations built on the Kibana platform. Here is what the dashboard looks like:

As we can see on the left-hand side of the preceding screenshot, it displays links to various dashboards. A MySQL performance dashboard, which displays the various queries used, performance of queries, and so on, looks like this:

MySQL Performance dashboard

A Web Transactions dashboard, which displays various web transactions, which includes the various HTTP methods used, total number of requests, error codes, and so on, looks like this:

Web Transactions dashboard

A MongoDB dashboard, which dispays MongoDB throughput, errors, errors per collections, input and output throughput, and so on, looks like this:

We can also explore multiple visualizations built in each of these dashboards. For example, a configuration of a GeoIP visualization, which plots clients across the geography, looks like this:
