Advanced Splunk

Chapter 2. Developing an Application on Splunk

In this chapter, we will quickly go through the process of creating an application and add-on on Splunk Enterprise. You will learn how to install and manage applications and add-ons on Splunk. You will also learn how to use different applications available on the Splunk app store to minimize your work using the already available applications for similar requirements.

The following topics will be covered in this chapter:

  • Splunk apps and technology add-ons
  • Developing a Splunk app
  • Developing a technology add-on
  • Managing Splunk apps
  • Splunk apps from the app store (covers examples and usage of a few apps from the app store)

Splunk apps and technology add-ons

It is very easy and simple to create a basic Splunk app or technology add-on using the Splunk Web console. We will also study how Splunk apps and add-ons can be manually created and configured in the further topics.

What is a Splunk app?

A Splunk app is basically a collection of all the dashboards, alerts, and visualizations created for a specific use case. It is a collection of an entire use case packaged in such a way that it can be installed on any Splunk Enterprise deployment to gain specific insight from the uploader, provided that its minimum requirements are fulfilled.

Splunk apps can be configured on the basis of user roles and permissions, thus providing a level of control when deploying and sharing the application across different stakeholders of the app. A Splunk app is created taking a use case into consideration and to avoid rework in case of the same use case or data sources. Splunk apps are applications that are ready to be used once the data...

Developing a Splunk app

Developing or creating a simple Splunk application is very easy in Splunk Enterprise, but developing a Splunk app that solves a business problem specific to a use case requires the following basic process:

  1. On-boarding data on Splunk: Using various data input methods to upload data on Splunk.
  2. Analytics: Using the Splunk search query language to create meaningful insights into the data uploaded on Splunk.
  3. Visualization: Creating visualizations for better understanding of the uploaded data on Splunk.

A Splunk app can include various components of Splunk Enterprise, such as data inputs, search queries, custom dashboards, macros, custom CSS, JavaScript, and many more…

Creating the Splunk application and technology add-on

The Splunk application framework works on a directory structure. All the installed and, by default, available applications are available at $SPLUNK_HOME\etc\apps.

The following procedure needs to be followed to create a sample Splunk app via the Splunk...

Developing a Splunk add-on

It is very important to first identify the problem that the Splunk add-on will solve. On identifying the problem, the following procedure is to be followed to create an add-on.

Building an add-on

It is very important to define the need and problems that the add-on will be solving before we build it.

If the add-on will be used to add data to Splunk, then how do we get that data into Splunk?

The various methods of data input are shown in the following screenshot. An add-on can be configured to use any one of them depending on the requirement and use case.

Building an add-on

You may wonder, what will the add-on do next? What configuration files need to be configured in the add-on for the given requirement? Add-ons can be configured for data acquisitions, data transformation, normalization, and enrichment. Add-ons can also be configured to have one or more than one features depending on the need:

Building an add-on

Installing a technology add-on

The steps to install technology add-ons via the Web and manually...

Managing Splunk apps and add-ons

Since you have learned how to create and install a Splunk application and Splunk add-on, we will now move on to how to manage apps and add-ons on Splunk Enterprise.

The following settings can be managed from the Manage Apps console of Splunk Web:

  • Permission management of Splunk apps and add-ons: Splunk apps and add-ons can be applied with specific roles and permissions, and we can also decide whether the app or add-on should be shared with other applications on Splunk. From the permission section, the object created in the application or add-on can also be shared in other apps by choosing Sharing for config file only object to all apps.
  • Enabled and disable applications and add-ons: All the applications and add-ons installed on Splunk Enterprise will be listed in the menu, and applications and add-ons can be enabled and disabled from this section.
  • Properties: The name of the Splunk application or add-on can be updated from this section. Other options such as...

Splunk apps from the app store

We went through the process of creating, installing, and uninstalling applications on Splunk Enterprise. Now, we will see some examples of applications or add-ons from the Splunk app store that can be used to solve common problems:

  • The Splunk add-on for the Oracle database: This add-on is available on the Splunk app store, and can be downloaded and installed on Splunk to connect with any Oracle database. Logs such as audit trails, trace files, incident, alert, listener, and other logs on the operating system where the Oracle database server is installed will be made available on Splunk, and thus, users can analyze, visualize, and create alerts on the uploaded data from the Splunk add-on for Oracle.
  • Browsing history analysis: Browsing history analysis is a ready-to-use app available on the Splunk app store that can be installed and used to analyze the browsing behavior of the user on the instance on which Splunk is installed. This app scans, extracts, and analyzes...

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
