Splunk, Where's my Props?!

Here’s the scenario. You find the perfect app for your data. You onboard the data, configure all your files, look through all your dashboards to finally see the views you have been waiting for. Then your greatest fear is realized, your dashboards are not working! You trouble shoot the searches in your dashboards and the fields that are needed for this search do not exist. Where are your field extractions?

Once you see that everything seems to be configured right on your app, you go through the TA apps you installed to make sure everything is working together. Everything seems to be...


Troubleshooting the Splunk App for Enterprise Security

Intro

Welcome Splunkers! In this post, I'd like to talk about an issue I encountered recently when working on a Splunk App for Enterprise Security v2.2.1 (ES app) deployment and the approach I took in troubleshooting it. But before getting started, I'd like to congratulate Splunk and their Security Products team for winning the SC Magazine Award for "Best Security Information/Event Management (SIEM) Solution." Cheers to a job well done!

Initial Installation

As per...


Taking a closer look

Ever have a well-formed search on Splunk that is running too slowly?  Of course, they can always go faster, but there are times when it really just seems like something is holding back your search speed. That leaves you wondering where in the chain of information transfer is the problem, really? And just when you're about to throw your arms up in despair: don't worry, job inspector is here!

The job inspector is one of those tools that Splunk provides which are often overlooked because of the plethora of other better-known tools. A quick glance at so many details in one...

Passing Time

System monitoring dashboards are something we are often asked to provide for our clients. Normally, this is a pretty straight forward task, but on a recent client engagement, I was presented with one requirement that was a bit out of the ordinary. This client was looking to monitor a set of ten desktops with a real-time dashboard that would display in their office. They wanted to see all of the standard metrics like cpu, memory, and disk. If there was a spike in a time chart for say % CPU Usage, they wanted to be able to click on the spike and drill down into another view. They wanted the...


Simulating Data with the Splunk Event Generator

While installing a new app to your Splunk search head can usually be considered a rather benign action, sometimes the introduction of a TA on your forwarders and indexers requires more attention.  This is commonly the case, especially if your production environment is guarded by change control.   The problem is that without the data generated by those inputs your newly installed app may not display properly, and without seeing your new app’s dashboards populated with data, you may not be able to conclude how useful it really is.  I suppose deploying a fully mirrored “dev” environment to...


Getting a Pulse on Your System: How to Build a System Health Indicator in Splunk

Welcome Splunkers!  I hope everyone is having a great New Year.  We certainly are, here at Function1.  We just publicly released a beta version of our Splunk for Oracle WebLogic Server app to Splunkbase  as mentioned in a recent post.  As part of the Splunk products team at Function1, I'm always looking at new ideas and approaches in Splunk app development.  As Splunk apps become more robust, they will...


WebLogic + Splunk = Splunk for Oracle WebLogic Server

As many of you know, from our website and blogs, we Function1-ers provide world-class consulting services for a few Oracle enterprise products as well as Splunk. Having this unique blend of experience on the Function1 team, we often try to experiment with new ideas that would be helpful to both sets of clients. One such experiment has yielded our new 1.0 Beta release of the Splunk for Oracle WebLogic Server app....


OH NO!! Splunking log files with multiple formats?? No problem!

I was recently at a client site  for a two-week engagement assisting them with ramping up their Splunk installation, and I came across something particularly interesting. One of the log files the client wanted to index in Splunk contained four different log formats with four different timestamps. Take a look at a sample of the log:

Splunk 5.0's Report Accelerator, better than Summary Indexing?

Over the last 3 years, I've worked with nearly 100 clients as a Splunk Professional Services Consultant across all sectors of business and have seen Splunk grow first-hand from the back office system admin's life saver, to the Enterprise Big Data Engine that it is today.  Splunk's latest 5.0.1 release is nothing short of amazing.  They've done the impossible, again - and they did it with their renowned Splunk personality.  It broadens the meaning...


Keeping your Splunk Deployment Server Organized

The following post is for Splunk administrators that are already somewhat familiar with the Splunk Deployment Server, and the deployment of configuration app packages. The scenario: As a sysadmin, no matter how much effort goes into planning and organization, there is the possibility that one day you will no longer be able to easily group your servers simply by their hostnames or IP addresses. It may be the result of an emergency change ticket...
