They say a picture is worth 1000 words. Actually it’s far more than that.
Take an Instagram image, there is tons of useful metadata behind the image – not just that tasty picture of what you had for dinner last night.
But how do you start to look at this data? I think you already know the answer to that! This post is just a quick guide showing you how to ingest and visualise Instagram data in Splunk.…
Splunk the Vote: BBC Election Debate
The third official debate has come and gone – this time without Cameron and Clegg. Perhaps this is why we saw the fewest tweets (179,000) collected during the debate compared to the previous two debate (216,000 & 312,000).
But how did the two leaders compare to those in the five opposition leaders who took part in the debate?
In the third part of my #SplunkTheVote series I took to Splunk to find out.…
git commit -a -m “Splunking Github Blog”
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.…
Splunking Social Media: Tracking Tweets
So you use Twitter and have heard Splunk can do “Big Data”. By tapping into Twitter’s API you can use Splunk to investigate the stream of tweets being generated across the globe.
The great thing about using Splunk to do this is that you have complete control of the data meaning it’s incredibly flexible as to what you can build. A few basic ideas I’ve had include tracking hashtags, following specific influencers, or tracking tweets by location in real-time.
What’s more, it takes a matter of minutes before you can start analysing the wealth of data being generated. This post will show you how.…
Splunking the World Cup 2014: Real Time Match Analysis
As an Englishman I’ve been waiting months – with very high expectations – for the World Cup to come around. Reading fellow Splunker, Matt Davies’ blog post titled, “Splunking World Cup 2014. The winner will be…“, only heightened my excitement.
The tournament is now going into the second week and I’ve been starting to look at the teams, players, and tournament more closely. Which stadium holds the most people? Who’s the top scorer? Which referee hands out the most cards?
With these questions fresh in my mind I opened up Splunk and began to have a look at the huge amounts of information being streamed from the tournament. For this post I’m going to explore real-time match updates; including teams, …
Getting data from your REST APIs into Splunk
More and more products,services and platforms these days are exposing their data and functionality via RESTful APIs.
REST really has emerged over previous architectural approaches as the defacto standard for building and exposing web APIs to enable third partys to hook into your data and functionality. It is simple , lightweight , platform independent,language interoperable and re-uses HTTP constructs. All good gravy. And of course , Splunk has it’s own REST API also.
The Data Potential
I see 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 …
SPLogger: iPhone Logging API
This week I put up on GitHub an early version of a Splunk logging API for iPhone developers, call SPLogger. We’d love feedback, code contributions, suggestion. The SPLogger API allows iPhone developers to log events in their application and have them go to Splunk Storm (www.splunkstorm.com), which is free for up to a GB of data. If you currently have no insight into how your app is being used, or by whom, this can come in handy, and of course you’ll have the full power of SPL, Splunk’s search language.
To get the SPLogger API, download it via either method:
Poke at our API
With this tool:
$ splunk _internal call <relative rest path>
[-get:<param> <value>] ... [-post:<param> <value>] ...
[-method <http action>] [-multival] [-auth <user>:<pass>]
As mentioned in my previous post, exploring our endpoints is pretty simple to do, by pointing your browser at the Splunk management port. Actually making use of the endpoints requires more work, but this utility makes it easy to get started.
Restarting an input component is a handy example, such as restarting monitoring after editing inputs.conf by hand:
splunk _internal call /data/inputs/monitor/_reload
This is supported by the other components in /data/inputs, as well – browse there and look for the _reload links.
- get:foo bar – adds an HTTP GET parameter to the request, with name ‘foo’
Talk to Splunk from WordPress
I wrote a WordPress plugin (tested for 2.5.1) that displays my most recent Google search terms in my sidebar. It was an experiment with using the Splunk REST API and the PHP SDK.
You can configure the widget from the Widgets page and it supports multiple instances with different configuration. Right now the actual search string is hardcoded because I’m doing some extra mangling to get the search terms the way I want anyway, but I’ll be adding that to the configuration options also. Eventually there will be a way to cache results so you don’t do the search each time the page is loaded.
Since there is still work to do to make it more generic, I haven’t uploaded …
