Introduction to Splunk Rest API

The organization of Splunk Rest API would be probably around object & configuration resources which may be the named, single and the object that are stored with the help of splunkd like a job, a TCP raw input etc. All the resources are then formed into one similar type of collections in which every single collection will have some type of combination resources along with the other collections.  

Then, Application Program Interface comply with the rules to the REST which is said to be an architectural style where it has below given following properties.

• All the concerns will be separated such as access mechanism & data storage between the client as well as the server.
• A client-server interaction which is also a stateless by excluding the session concept.
• Operation data catching will be used to enhance the performance of request-response
• An interface which is generalized and also uniform for simplicity
• The arrangements of the layer of REST architectural components which are arranged such a way in a hierarchically & contain their respective information that is out of scope by avoiding source of information to the nodes.

Most of these properties of architectural will be aligning with the implementation of REST API that can use the corresponding points and can also access domain resources with the help of it and can also be done by using HTTP protocol. Users can also use the same protocol for sending an request of the Application Program Interface to the server if the browser uses same protocol only. From the HTTP protocol maps to next of the Splunk platform resources, the URL addressing is defined as part of it & is also identified by the Uniform Resource identifier.

What is Splunk REST API?

An API (Application Programming Interface) is used to define Interfaces to a programming library or else framework for accessing functionality provided by framework or library. The Splunk Enterprise REST API will provide various methods or steps to access every product or feature.

Here are the access methods provided by the Splunk REST API

1. Delete: A resource should be deleted
2. Get: Present state data can be associated to the list child resources or else any of the resources 
3. Post: You can also create the resource data as well as update it & will also enable & disable resources functionality

How to connect to splunk?

By using Splunk REST API, one must rely on or use the splunkd management port, 8089, and the secure HTTPS protocol. One can easily set the enableSplunkdSSL property on the server.conf file to false to use the unsecure, HTTP protocol. 

How to get data from REST APIs into Splunk?

By using the REST Modular input, Firstly, go to the Splunkbase & download the latest release. Then go to SPLUNK _HOME/etc/apps & restart Splunk. Then, perform the configuration & then navigate to Manager, then Data Inputs & then to REST. After that, click on ‘NEW’ button to create a new REST input & fill up the fields that are noticed. After performing the entire process, search for the data which are in RESTful responses that are in JSON format, which will be very convenient for auto field extraction.

What is the use of Splunk MINT REST API?

The Splunk MINT REST API is used to retrieve insights, upload dSYMs & manage projects & teams as well. This interface will also incorporate with various elements of the REST tradition & will also make access to these actions in a consistent way.

How to access endpoints & REST operations?

To access endpoints & REST operation, Username & password is must where the Splunk users should have role & authorization that is based on the capability for using REST endpoints. An role of the administrator among the users like admin can have easy access to the information in the Splunk Web. Follow the below process to have a look at the roles that are given to a user, First,  go to the  settings, then access controls & click on the Users. Follow these process for determining the role capabilities, go to the settings, then go to access control & then click on Roles. The authentication session timeout is generally for one hour by default that is configurable using the session will be timeout setting in server.conf file general stanza.

Frequently Asked splunk Interview Questions

What is HTTP Status Codes in Splunk REST API?

In addition to content data, the responses which you have received will be having the HTTP status codes, which are not even included in the endpoint descriptions as the implementation is following the standard of HTTP which is used to report status. There are certain noted for the documentation of  status codes by giving vital importance for the endpoints or else the standard of the Splunk software will be different from the regular standard.

What are the main response elements?

The important response message elements are listed here to view: Metadata encapsulating the content element.

The > Key/value pair data payload. The endpoints return a list of entry elements which are sort by the entry name by default.

What is Encoding scheme and explain it with examples?

The Splunk REST APIs will probably support multiple encoding schemes but not all the schemes that are supported by the endpoints. The REST API Reference Manual will have the list of the valid encoding schemes of each endpoint. XML is considered as the default encoding scheme for most REST API endpoints and it is used by the documentation examples.

Users can also append the output_mode parameter as a query string for specifying a supported encoding scheme besides XML. Here are some of the examples which are the responses returned by using different encoding schemes, scv, json, json_cols, json_rows, raw & XML. The endpoint also gives an error response if the specified encoding scheme is not supported.
