What Exactly is Splunk?


Splunk is an ingenuous technology that indexes and searches log files, and assists businesses gain insight from the information. One of the main advantages of Splunk is that it makes use of indexes to store data and therefore does not require an additional database for the data.

Splunk is used to monitor and search through large amounts of data. It organizes and integrates data in a way that makes it searchable and allows you to generate reports, alerts and visualizations. It can detect patterns in data as well as create metrics to help to identify problems to address business issues such as managing IT, security and compliance.

Making use of Splunk to perform Machine Data Analytics

Splunk can help organizations extract value from server information. This allows for efficient management of applications as well as IT operations management security and compliance security monitoring.

The core of Splunk lies in an engine that gathers large indexes and manages data. It is able to handle terabytes of data, or more, in any format, every day. Splunk analyzes data in a dynamic manner by creating schemas in the background, which allows organizations to search for data without having to know the data structure first. It’s easy to load the data in Splunk and then immediately begin the analysis.

Splunk is able to be used as a stand-alone laptop, or as part of a large distributed structure inside an enterprise data center. It offers a machine-data fabric that includes forwarders, indexers, and search heads (see our post on Splunk architecture) that allows real-time collection and indexing of machine data on any data center, network and IT infrastructure.

The introduction to Splunk Hunk: Splunk on Hadoop

Hunk is a substitute for Splunk Enterprise which is provided and provided by Splunk to analyze machine data that is stored in Hadoop. It was in the past that numerous organizations stored the machine’s data into Hadoop as it was the most popular tool for storing and analyzing huge amounts of data. In the present, as the Hadoop infrastructure ages, companies struggle to deal with the limitations of this tool.

Hunk is an Splunk big data tool created to help you explore and visualize data from Hadoop clusters as well as NoSQL databases such as Apache Cassandra. As opposed to writing codes in Hadoop for each data-related query you have to ask, Hunk provides an integrated experience that doesn’t require any special expertise and will help you discover insights from massive data, without the need for specialized schemas or a huge development effort.

Hunk can assist organizations in making more use of Hadoop datasets through:

The Splunk technology stacks with Hadoop and lets you build dashboards and share reports on the same platform that integrates with Hadoop in the back-end.

Create an Splunk Virtual Index that helps to separate Hadoop storage of data in relation to data access, analytics and to allow interactive analysis and exploration that was normally not possible using Hadoop.

It makes it easy to build applications that leverage Hadoop big data. Hunk offers a web framework that allows developers to access Hunk by using tools that are familiar to them, such as XML, JavaScript and Python/Django.

Offering the Splunk Search Processing Language, as in Splunk Enterprise. Splunk Enterprise software, which assists in detecting patterns and anomalies in large data , and locating interesting data in petabyte-scale Hadoop clusters.

Finding data correlations by using Splunk DB Connect, to cross-reference data from structured files stored in Hadoop with data stored in an existing relational database. Hunk allows you to transform these correlations right away into visualizations and dashboards that you can share with other users.

Rapidly responds to queries on massive amounts of data within Hadoop and also provides additional capabilities such as access control, stored statistics and scheduling.

Key Capabilities of Splunk Hunk

Hunk is able to perform the following tasks:

Exploring data with Hadoop: explore data dynamically across huge databases without having to analyze the data’s structure or establish schemas. It facilitates more thorough analysis, and allows users to identify anomalies, recognize patterns and enhance insights by connecting information from relational databases.

Visualizing and reporting Hadoop data – create graphs, charts and other visualizations based on Hadoop data in order to provide value to others within the company. The reports are available for sharing via any device.

Custom dashboards–convert charts, views , and reports in interactive dashboards. They are viewable on mobile and laptop computers as well as having security and control of access built into.

Do You Need to Make Use of Hunk as well as Splunk Enterprise?

When your information is kept inside Hadoop, Hunk is the most obvious option since it can work directly on the data without requirement for massive-scale data intake. However, if you are given the option of removing data from Hadoop it is a matter of whether it is better to change between Hadoop and onto Splunk Enterprise.

Benefits of Hunk:

Hunk generally uses less disk space than Splunk Enterprise, reducing storage costs

Hunk allows you to keep your data in Hadoop in the original format and allows you to make use of tools within the Hadoop ecosystem

Benefits from Splunk Enterprise:

In many instances, searches within Splunk Enterprise run much faster than Hunk on Hadoop

Supports real-time search This isn’t feasible using Hadoop. The latency can be lower in long-running searches.

It is possible to use Splunk Forwarders to access log data from a wide array of IT systems, however it isn’t always easy to constantly transfer information from these sources to Hunk.

Cut down Splunk Storage costs by up to 70% by utilizing SmartStore and Cloudian

Splunk’s newest SmartStore feature lets it use the indexer feature to search for data stored on cloud storage, such as Amazon S3. HyperStore is an S3-compliant exabyte-scalable storage pool on-prem which SmartStore is able to connect. It allows you to decouple storage and compute in the Splunk architecture and increase the size of storage independent of cloud computing resources.

HyperStore is also equipped with full Apache Hadoop integration for Splunk Hunk users. The authorizations are able to use Hadoop analyses using HyperStore appliances, without the need to transfer data to another system. Under the underneath, HyperStore uses S3FS as the basis for HDFS which allows users to perform Map Reduce jobs on top of the data that is stored on an appliance.
