You must be logged into splunk. Go to Subscription. That's it! Jiji Abhilash. Assumptions There are a few basic assumptions that we are going to make.
What am I trying to accomplish? Search-time extractions? Index-time parsing? Dashboards to share? Who is my target audience? These questions can help you spark an idea of what internal resources would need to be engaged, as well as any kind of documentation and educational requirements.
Identifying what you want to consume Once you have determined the scope of the App, you will need to decide how and from where you will consume the data. Getting data into Splunk can happen in a very wide variety of ways. There is no set manner of input that will work on all data sources. You may have to develop a new script or modular input. Being aware of where your data is coming from is the key to getting it consumed correctly the first time.
A few questions you may ask yourself could be:.
How do I get the data? What format is the data? Is it already extracted or well known, like syslog , or do I need to write custom extractions? There is a lot of data out in the wild, but not all of it may be relevant to your use case.
You may find that of a service that has endpoints available for data collection, you only need Not only will you save on license usage, but your indexers will thank you for it as well.
Identifying what you want to brand Another key thought process in App development is how far you want to brand your App. Splunk has a very robust architecture and framework, providing you with the ability to customize your Apps extensively. You can override any individual piece of CSS and extend SplunkJS Stack to include any number of different visualizations or third-party libraries.
Additional questions you might ponder on would include:. Do I need to engage an internal graphics resource to design and create App icons? App logos? Am I going for mobile or static desktops? What desktop size is typical of incoming users?
To what extent should I customize my App? There are so many options available to brand your App, but all customizations should conform to the Splunk branding guidelines for developers. Visit http: Identifying what you want to display Once you have the whats and hows of the data you're going to collect, you need to figure out visualizations. How you display the information is just as important as what data you collect.
Splunk comes with a variety of graphs and displays right out of the box, and can be extended quite easily to include some really cool presentations.
Some of the questions posed to you might be:. Do you need a programmer to write custom modules or extend SplunkJS views and managers? What third-party graphing or graphic libraries do you need to document, develop, or get permission to use? Do you need to engage a statistician to determine the best and most effective way to display your data? Some stats such as max, mean, and min are easy, others such as confidence intervals and trendlines are not.
Such a small list of questions hardly precludes any other relevant discussion within your organization. The more internal discussion that can take place, the better and more thought-out your App may turn out.
Installing Apps As a Splunk developer, you should be aware of the three methods to install Apps. There are advantages and disadvantages to each method, but no required method. It is mostly personal preference as to which method is used by the end user, but, typically, newer Splunk users will use the Web interface, while advanced users will use the command line.
Let's review those methods, just to keep them fresh in your mind. Once you have downloaded the App from its source, you navigate to the Manage Apps section of Splunk. You will find this at the top-left of Splunk Web, as shown in the following screenshot:. Once you have clicked on Manage Apps, you will see a button to install the app from a file. You can also browse the Splunk App store, using the first button:.
This brings you to a form that you can use to actually install the App. Simply click on the Browse button, select the file you downloaded, check the Upgrade button if this App has already been installed, and then click on Upload.
That's it! Splunk takes the App, installs it, and prompts to restart if needed:. It is entirely possible to install Apps via the command line alone. Doing so requires having the following: Follow these steps to install an App via CLI: Run the. Splunk will install the App. You may be prompted to restart, depending on the contents of the App. Index-time configurations require a restart, whereas search-time configurations do not.
If the App was constructed properly, the only steps you need to perform are as follows: Change the file extension from.
Use your favorite utility and unzip the file into the folder. This will overwrite any other settings you have configured, including local configurations if present in the zip file.
We will cover directory structure in the next chapter. Downloading the example code You can download the example code files from your account at http: If you purchased this book elsewhere, you can visit http: Summary In this chapter, we covered the basic fundamentals of designing and installing Splunk Apps.
Apps can be broken down into domains, each with a naming convention that allows you to quickly determine what the App can do, and what is contained within it, so that new users to your environment don't have to look for configurations.
We learned how to approach App design to make sure that the App is planned beforehand, which will eliminate the need to refactor major portions of the App later, when it may already be in production. We also went over the three different methodologies available to install Apps to give a basic understanding of user experience related to the installation of any App you may build.
Now that you've acquired an understanding of what an App consists of, in the coming chapters, we will discuss creating, enhancing, and customizing them. Alternatively, you can buy the book from Amazon, BN. Click here for ordering and shipping details. Chapter No. Flag for inappropriate content.

Specific roles? What kind of information will I be presenting? Server based? Metric based? A few questions you may ask yourself could be: Why do I need this data?
Is it all completely relevant to my use case? Where is the data? Cloud, SaaS provider, internal network? Additional questions you might ponder on would include: Do I want to brand anything at all, or just stay with native Splunk?
