What is elk and Kibana?
ELK stands for Elasticsearch, Logstash, and Kibana. In the ELK stack, Logstash extracts the logging data or other events from different input sources. It processes the events and later stores it in Elasticsearch. Kibana is a web interface, which accesses the logging data form Elasticsearch and visualizes it.
Why elk is better than Splunk?

Importance & Issues
For the North Coast and Cascades Network, we selected elk for monitoring over several other potential wildlife species or groups of species because of their potentially large influence on ecosystems where they occur and the many agents of change that are expected to influence future elk populations. Because elk are important agents of ecological change within park ecosystems, reliable information on trends is needed to interpret changes in the health of park ecosystems.
Monitoring Objectives
Monitor trends in elk abundance, distribution, and herd composition in selected subalpine summer ranges in Mount Rainier and Olympic National Parks.

What is ELK Stack
If you are looking for a simple explanation, I will say ELK stack is the combination of three open source tools. Elasticsearch, Logstash & Kibana. When these three combine together and form a tool/platform for the log management system. It allows you to search all the logs in a single platform.
Elasticsearch
Elasticsearch is basically a search engine. A highly scalable search engine which runs on top of Java-based Lucene engine. Elasticsearch allows you to store, search and analyze huge volumes of data so quickly and in real time which gives back your search results in a fraction of seconds.
Logstash
In order to search data we need to collect the data first. logstash is the data collection pipeline tool. It is the tool which collects data and feeds into Elasticsearch.
Kibana
Kibana is an open source visualization and analytical tool which completes the ELK stacks . Main use is to visualize the Elastic search documents and helps developers to have a quick awareness of it. Kibana simplifies the huge volumes of data and reflects the real time changes in the Elasticsearch queries.
Beats
As you all know while receiving, transforming and sending data, there can be performance issues. Here comes the role and its importance of Beats. Beats is a free and open platform for single-purpose data shippers. They send data from thousands of machines and systems to Logstash or Elasticsearch.
Why is ELK used in analytical workloads?
ELK can provide medium scale analytical workloads because it is designed to be horizontally scalable. Using elasticsearch aggregration queries, a lot of insights can be queried. However, the ingestion of data might not be as performanant compare to other tools. Cpu, memory, swap, network, disk, sockets.
What is the ELK stack?
The ELK stack consists of the technologies; Elasticsearch, Logstash, and Kibana. It works very well to provide a centralized logging and monitoring. Elasticsearch is the datastore for the log data. Kibana is the web interface that provide visualization on the data. Logstash sits between log data sources and Elasticsearch, to parse the logs.
What is a metricbeat?
Metricbeat: Collect metrics from System, cpu, memory, disk. From services like Apache, Postgres, Redis, etc.
Does Kibana have real time monitoring?
In terms of real time monitoring, Kibana provide ability to create dashboards and then auto refresh them every few seconds. Automated monitoring, can be done using elastalert plugin by yelp, so we can write queries to detect abnormalies, and the fire off notifications to slack/email/pagerduty/etc.

Why do you need to run Elasticsearch in different zones?
This can be done through an Elasticsearch setting that allows you to configure every document to be replicated between different AZs . As with Logstash, the resulting costs resulting from this kind of deployment can be quite steep due to data transfer.
Why do you need a buffer in Kafka?
As mentioned above, placing a buffer in front of your indexing mechanism is critical to handle unexpected events. It could be mapping conflicts, upgrade issues, hardware issues or sudden increases in the volume of logs. Whatever the cause you need an overflow mechanism, and this where Kafka comes into the picture.
