What is meant by ELK Stack?
It is defined as a collection of three types of products that are of open source like Elasticsearch, Logstash, and Kibana. The main objective of ELK is to detect the problems with the applications or servers. It can also be used to allow the user to search the logs in one place. Besides, the above parameters, one is able to find the issues with different servers connecting in a specific time.
ElasticSearch, LogStash and Kibana are all managed, developed, and maintained by a single organization / company called Elastic.
The main objective behind designing this ELK stack is to allow us to take the information / data from any type of source, search, analyze and in any type of format to visualize the data.
What is meant by Elasticsearch?
It is known as the NoSQL database and it is built with APIS of RESTful. It is used to provide maximum reliability, simple deployment, and to easy management. It offers very advanced queries to perform a detailed data analysis and stores the data to execute the quick search documents.
Elasticsearch can also be used in storing and analyzing the data which are of big volumes. It is most often used in engines underlying to power the applications which completed search needs and requirements. It is adopted in the platforms of search engines for mobile and web applications. Besides these features, this tool can provide many more advanced features.
Elastic search features:
- It is used to index the heterogeneous data.
- It can be written using Java in the open source search server.
- Full-Text Search.
- REST API web-interface.
- Replicated searchable, Sharded, and JSON document store.
- Near Real Time (NRT) search.
- Geolocation and multi-language support.
Benefits of Elasticsearch:
- It can create the data schema and also stores it.
- Perform querying and filtering the insight data.
- Manipulate the recorded data.
- Provides reliability, scalability, and indexing in order to make the fast search.
- It can provide RESTful and Apache Lucene.
- Helps the users to scale horizontally and vertically.
What is meant by Logstash?
It is defined as the collection of data through a pipeline tool in order to collect the data inputs and feed to the elasticsearch. It can also combine different types of data sources for the future usage. The Logstash can be used to unify the data from the various sources into targeted destinations. It also allows us to democratize the data for visualization and analytics.
Basically, the Logstash contains three components:
- Input: It is used to process them in the machine understandable language.
- Filters: It is defined as the set of conditions in performing an event.
- Output: It is used for proceeding a log or an event.
Logstash Features:
- Events can be passed through internal queues.
- Parsing or filtering the user’s logs.
- Allowing various log inputs.
Benefits of Logstash:
- Provides the data processing centralization.
- It is always plug-in to the several types of input platforms and sources.
- It can analyze both structured data and unstructured data.
What is meant by Kibana?
It is known as a data visualization which can be used to complete the ELK stack. It is considered as the best tool that helps the developers get quick insights into overall data. The dashboard of Kibana provides several geospatial data, interactive diagrams, and complex visualization of queries.
Kibana is used for searching, interacting, and viewing the information / data that is stored in the directories of elasticsearch. It will also help the user in performing advanced data analysis. It ensures the users to visualize the data in several varieties of chats, tables and maps.
Kibana features:
- It has a good front-end dashboard that is capable of indexing the data / information from the cluster of elastic.
- The user can search, interact and view the data / information.
- It can enable the real time index search information.
- Execute on information source and visualize the output in maps, tables and charts.
- It has the capability to provide historical information / data in the forms of charts, graphs and so on.
- The dashboard of Kibana provides several geospatial data, interactive diagrams, and complex visualization of queries.
- It has the real time dashboards to be configurable very easily.
Benefits of Kibana:
- It is fully integrated with elasticsearch.
- It can provide easy visualizing.
- Provides real time data analysis, summarization, charting, and capabilities of debugging.
- Allows the users to share snapshots.
- Permits in managing and saving various dashboards.
