Updating the iplocation db

When Splunk added the new version of the iplocation command in v6.0, it added the ability to add location info without the need for internet concenttivity. We did this by shipping a custom version of the MaxMind DB in the 6.0.x release. However, because we used a Splunk specific version of the DB, you still had to wait for a new version of Splunk to get a new copy of the DB.

In 6.1 we added support for using the native MaxMind DB (.mmdb), allowing you to update the DB yourself at anytime! It looks like some of you have already figured this out (Go George go!), but I figured I would add some additional info about this …

Splunk + Cloudera for Hadoop–Better Together

This is a guest post contributed by Amr Awadallah, Ph.D., Co-Founder and Chief Technology Officer, Cloudera

On July 23, my friend Todd Papaioannou and I are co-hosting a webinar on a subject that’s very important to me. As co-founder and CTO of Cloudera and a long-time Hadoop user dating back to my days at Yahoo, I recognize that big data, for all its promise, also comes with its share of challenges. A central one being how to make data exploration and analysis on petabyte-scale datasets across distributed systems accessible to people without advanced data science backgrounds.

That’s one of the things I really like about Hunk, Splunk’s analytics and visualization solution for Hadoop. It’s a powerful platform that allows you …

Deploying Splunk Securely with Ansible Config Management – Part 1

Intro

More times than not I have seen corporations struggle with config management and it is key for concise mitigation and remediation plan. Interfacing with a variety of Splunk customers the corporations whom do implement a config management system usually have a different tactic on how to manage Splunk while doing it in a secure fashion. In this series of blog posts which will hopefully walk you through a simple deployment of Ansible all the way to the most complex use-cases I have seen. I will first be covering how Ansible can be leverage to manage a simple Splunk deployment on your own hosts. Part 2 we will cover how this can be done in a larger scale with EC2 …

Monitoring Local Administrators on Windows Hosts

It is always gratifying when one of my readers comes to me with a problem. I love challenges. This one had to do with one of my old posts surrounding Local Administrators remotely. Of course, the way to do this is via WMI. However, it doesn’t quite work the same way locally. This is because the WMI call to Win32_Group.GetRelated() returns other stuff as well. So the question posed was “how do I get the list of Local Administrators locally.” More specifically, I want to monitor the local Administrators group.

I look at this two ways. Firstly, I want to get a regular list of names in the Administrators group and secondly, I want to monitor for changes to the …

Splunking web-pages

Have you ever had a situation where you found information on a webpage that you wanted to get into Splunk? I recently did and I wrote a free Splunk app called Website Input that makes it easy for everyone to extract information from web-pages and get it into a Splunk instance.

The Problem

There are many cases where web-pages include data that would be useful in Splunk but there is no API to get it. In my case, I needed to diagnose some networking problems that I suspected was related to my DSL connection. My modem has lots of details about the state of the connection but only within the web interface. It supports a syslog feed but it doesn’t include …

Big data just got its Tricorder

Tricorder

In Star Trek a Tricorder is described as:

“A Tricorder is a multifunction hand-held device useful for data sensing, analysis, and recording data, with many specialized abilities which make it an asset to crews aboard starships and space stations as well as on away missions”.

I’m happy to announce the launch of the Splunk Mobile App, which unofficially I’m calling the “Big Data Tricorder”. You can download it from here (iTunes).

The Splunk Mobile App allows you to take the Splunk (Starship) Enterprise platform and allows you to explore strange new insights, to seek out new data and new visualizations, to boldly go where no machine data has gone before.

You can find more in the official press release here

Splunking Social Media: Tracking Tweets

splunk-blog-twitter-dashboard

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.…

Quick PowerShell Script to Start Splunk

Got another quick PowerShell post for you. I have a copy of Splunk running locally on my Windows 8.1 workstation. I don’t always leave it running, for obvious resource reasons, therefor I end up starting it and stopping it as needed. On Windows, there’s two ways to control the Splunk services:

  • CLI splunk.exe start|stop|restart commands
  • Windows native service control methods (and there’s a half-dozen ways to do that)

So, in PowerShell, you can just do this:

Get-Service splunk* | Start-Service

The only minor problem is that I keep forgetting to elevate my PowerShell shell, so I’ll get an error message, and then I have to open a new window, and then repeat the process.  That’s no way to automate, I said to myself, so I made this quick …

Splunk Alerts: Using Gmail, Twitter, iOS, and Much More

splunk-blog-alerts-twitter

With no programming required!

One of the great features about Splunk is its built in alerting functionality. You can configure Splunk alerts to do just about anything, from sending an SMS to integrating them with another app, like ServiceNow for example.

Most Splunk users will probably want to configure alerts via email at some point. If you don’t have your own mail server you can use web based mail services like Gmail to do this. In this post we’ll explore how you can set this up and some neat ways in which you can extend upon native Splunk alerts.…
