Troubleshooting connectivity issues to Splunk’s API from the SDK

A common problem we see customers struggle with is how to diagnose connectivity issues with any of our SDKs. In this post, I’ll show you a few tried and true practices that can help you figure out what might be going wrong.

There are two main families of errors folks see. One has to do with general connectivity / connection info, and the other has to do with security config on the client.

General connectivity issues 

This means that you are unable to succesfully connect to the API. The best way I find to diagnose is to drop to a terminal and use curl to login to the Splunk API and see the results. The command to use is:

The Splunk SDK for JavaScript gets support for Node.js v0.12 and io.js!

We’ve just released an update the Splunk SDK for JavaScript, v1.7, with some great new features! Most importantly support for Node.js v0.12.x and io.js.

You can get it on npm or GitHub, and docs are available at dev.splunk.com

New features and APIs

  • Added Service.getJob() method for getting a Job by its sid.
  • Added Service.ConfigurationFile.getDefaultStanza() method for getting the [default] stanza of a conf file.
  • Can now stream JavaScript objects with modular inputs by passing an object as the data parameter to the Event constructor; that object will then be passed to JSON.stringify().
    • Updated the GitHub commits example to show this functionality.

New Examples

  • The node/helloworld/get_job.js example shows how to get a Job by its sid.

Announcing the Splunk Developer Guidance

Greetings, Splunk Developer Community!

This week we are announcing the new Splunk Developer Guidance program at the Splunk Partner Summit Americas 2015. The main objective is to provide our developer community with tools and guidance to build amazing apps on the Splunk platform and enrich users’ experience in gaining insights from their machine data – where ever it might come from and whatever domain they might be specializing in! We are fully aware that the first thing most devs are looking for is code that they can take apart, learn from, and reuse. That’s why we built reference apps for you. The reference apps are complete, end-to-end, real-world apps built with our partners that are meant to showcase various underlying …

Github Splunk Analysis

I <3 Github. Splunk <3’s Github (check out our repos here). I am told it is just a coincidence our HQ is opposite theirs.

One of the neat things about Github I am just starting to explore is their API. You can use it to do loads of things, from interrogating user activity to searching for keywords within code. I recently saw this analysis of the most popular programming languages hosted on Github and I was inspired to recreate it within Splunk.

Indexing Github data into Splunk makes it super-simple to start exploring it. In this post I wanted to show you some of my first experiments connecting Splunk into the Github API.…

Splunk App for Salesforce

Do you manage a Salesforce environment and would like to analyze who is accessing what? Would you like to find out who is exporting sensitive data? Would you like to detect any Salesforce related suspicious activities or any slow running reports, dashboards, SOQL queries?

If the answer to the above is yes, you should check out the Splunk App for Salesforce which has been recently released as a service on Splunk Cloud. This App relies on the Salesforce Event Log File that exposes Salesforce access logs. In addition to that, you can also leverage this app to collect and index any data from the standard Salesforce objects. In other words, you can use this app to index structured and unstructured salesforce data.

Notes on Splunk CIM

So you want to work with the Splunk Common Information Model, and you’re not sure where to start… developers first working with the CIM and Add-ons are sometimes confused by its minimalist design, particularly if they’re familiar with the broadly used Desktop Management Task Force CIM. Here’s some notes on the CIM’s design that hopefully will help clear things up. First, we’ll look at how it’s used, and then we’ll talk about why the Splunk CIM is designed the way that it is.

The Splunk CIM describes concepts via tags rather than entities via database columns, and the first thing to understand when you’re trying to work with it is the event type. Events are the raw material …

A custom search command for Yelp

A while ago we posted on search commands and how to build a basic generating command which creates dummy “Hello World” events. Generating commands can be used for much more including talking to external APIs. For example, a fun command to think about would be allowing you to search for restaurants, theaters, etc using Yelp’s API. We’ve posted a sample Yelp search command that does just that. You can find it on github here.

Using the command you can do things like search for Sushi and Italian restaurants in SF:

| yelp location="San Franciso" term=sushi,italian

Or if you are an adventurer, you can find out where to make that next skydive when you visit New Zealand :-)

SMail: Splunking Your Inbox

Splunk GMail

Google sent me a nice message to start the year – “Your inbox is reaching its limit”.

Looking at my GMail inbox I have well over 70k emails, taking up just under 15GB of space. I’m interested in how this number is made up – who emails me the most, who I email, what time I’m most productive, etc.

I decided to download my GMail archive using Google Takeout to analyse the data. Here’s how I did it.…

SSSL (Splunk Secure Sockets Layer)

Splunk SSL

The primary reason why SSL is used is to keep sensitive information sent across the internet encrypted so that only the intended recipient can understand it.

This is important because the information you send on the internet is passed from computer to computer to get to the destination server. Any computer in between you and the server can see your credit card numbers, usernames, passwords, Splunk searches and other sensitive information if it is not encrypted.

When an SSL certificate is used, the information should become unreadable to everyone except for the server you are sending the information to. This protects it from possible prying eyes.

It is often important to make sure the connection from Splunk Web to the …

Splunk Traffic Lights

Splunk ships with some really neat visualisation options. From bar charts to gauges. Though sometimes they just don’t fit your requirements.

Wether that be something as simple as an custom icon or a super-slick D3 visualisation, Splunk’s framework makes it really easy to display your data in many number of ways.

One of the things I get asked a lot is: “Can we have a traffic light?”. The answer – yes! Let me show you how to light Splunk up in this post.…
