Lack of visibility across the product development lifecycle

Slows down the ability to detect and troubleshoot errors

Limited visibility into application usage and performance

Modular Inputs

22

Modular Inputs• Extend the Splunk framework to define a custom input capability, just like the standard inputs you are

familiar with (TCP/UDP/File etc…)

• Splunk treats your custom input definitions as if they were part of Splunk's native inputs, totally integrated first class citizen objects in Splunk

• Users interactively create and update your custom inputs using Splunk manager, just as they do for native inputs.

• When deploying without a UI , you push out the inputs.conf file.

• All the properties are fully manageable via the REST API

• Version 5.0 +

23

Developing

24

• My preference is to use Python, however any language can be used.

• http://docs.splunk.com/Documentation/Splunk/latest/AdvancedDev/ModInputsIntro

• There is a certain amount of “plumbing” to put in place , so I like utilities that take care of this for you, so you can just focus on the business logic.

• Java,Python,C# SDKs also have Modular Input APIs

• Eclipse plugin has a wizard for creating Modular Inputs in Java

REST : The Data Potential

25

Twitter FoursquareLinkedIn Facebook Fitbit Amazon Yahoo Reddit YouTube Flickr Wikipedia GNIP Box

Okta Datasift Google APIs Weather Services Seismic monitoringPublicly available socio-economic dataTraffic data Stock monitoring Security service providers Proprietary systems and platforms Other “data related” software productsThe REST “dataverse” is vast , but I think you get the point.

There is a world of data out there available via REST that can be brought into Splunk, correlated and enriched against your existing data, or used for entirely new uses cases that you might conceive of once you see what is available and where your data might take you.

You are only limited by your own “data imagination”

Demo

Custom Search Commands

Splunk Search

29

Splunk’s search and querying language is called SPLAllows you to search, analyze and manipulate your data.Designed with the “unix pipeline” in mind – a “search pipeline”

From a (simplistic) mental point of view:– Series of commands– Each commands takes the input of the previous one– Each command outputs a sparse table

Splunk Search - Example 1:

30

“index=_internal foo | eval bar=... | stats count by bar”Initial command fetches result from index/raw data store, and outputs a table, with a row for each event, and a column for each field (not all rows have all columns)Second command adds a new column to each row, “bar”Third command looks at all the unique values of “bar”, and counts how many rows each value has.Note that the last command completely transformed the table, hence it is a “transforming” or “non-streaming” command.The second command was merely additive, known as a “streaming” command.You can also have “generating” commands ie: inputlookup

Custom Search Commands

31

Just like the “eval” or “stats” commands, you can write your own “search commands”.Python scripts which take data on stdin, and output data on stdoutData comes in/out as CSV (with special handling for MV fields)Many of Splunk’s builtin commands are written as Python scripts (e.g. head, return, transpose)

Custom Search Commands: Building Blocks

32

Custom search commands are built in two parts:

A Python script containing the implementation

An entry in commands.conf declaring configuring the command

Splunk SDK for Python has librarys and examples for creating custom search commands

Managers• Search Query Wrappers• SearchManager and SaveSearch

Manager• Include Search Parameters• Available within Django or

JavaScript

Splunk JS Stack & Django Bindings Concepts

37

Splunk Views• UI widgets• Designed to work with Search

Managers• Charts, Maps, Inputs, Timeline,

TimePicker, etc.

Splunk JS Stack & Django Bindings Concepts

38

URL Maps & Django View• URL Maps enable custom routes• Django Views, enable custom logic

to provide to templates

Splunk JS Stack & Django Bindings Concepts

39

Templates & Template Tags• Templates enable quick layout

options • Templates support inheritance of

other templates• Tags call a Python function can be

used for:– Text manipulation– Flow control– Load external information– … and more

Splunk JS Stack & Django Bindings Concepts

40

Data Binding using Tokens• Token based data-binding

mechanism that keep shared data in sync.

• Enables in-page interactivity

Web Framework Toolkit App

41

• Improved productivity for developing your own Web Framework based apps

• Reusable Visualization• Packaged to lower the effort of adding cool

visualizations• Improved Developer focused Command Line

Tools• Getting started templates• Automates common tasks

• Includes examples pages demonstrating advanced concepts.

SimpleXML converted to HTML

Custom Visualizations

50

My Guiding Viz PrincipleThe visualization must be simple and intuitive to understand and derive meaning from at a glance.

Cool viz , but what are you telling me ?

So many options , which one for me ?Splunk Web Form Editor– If you are not a coder , not familiar with Simple XML

Edit Simple XML– Familiar with Simple XML , what to customize more

Convert Simple XML to HTML/JS – Coder , want to see the underlying JS/HTML , want custom UI behavior above Simple

XML, want to use some other JS/CSS

Simple XML JS Import– Closely related to the above , perhaps you still want dashboard editing / PDF export

Django– Previous benefits + want to leverage Django tags , want custom server side processing in
