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.

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...

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...
Organizing Your Splunk Shoe Rack (Defining Index Structures , Part 2 of 2 )
In my previous post, I went through the thought process of defining a Splunk index structure. There aspects of defining this structure were covered: data access control, data retention, and search performance. Now that we understand the case for a well-defined index structure and the different factors that drive it, let's go through a use case.
An extremely bright and talented system administrator at the Panda Shoe Company (fictitious) wanted to work smarter and...

I was a recent attendee of Splunk’s worldwide user’s conference .conf 2012. It was held at the ultra modern and chic Cosmopolitan Hotel located in the heart of Las Vegas, Nevada. Over 1000 people attended the conference and there were 90+ information sessions geared towards a wide range of Splunk user levels. At any given moment over the 3-day conference, there were 12-16 sessions going on at the same time. There was literally a world of knowledge being handed out to anyone who...

Your Splunk Shoe Rack
When splunking with a new customer, one the first things I review when auditing their environment is their index structure. Why? Well there's a lot you can tell about the maturity of a Splunk deployment based on this particular configuration. The old saying that Forrest learned from his mom comes to mind...

Monitoring Weblogic Environments
If you work with Oracle Weblogic Server(WLS) in an enterprise environment, then you likely have many managed servers, clusters, applications, and services that you have to keep an eye on. The clusters and instances in a Weblogic domain add to the complexity of the application infrastructure. So how is a Weblogic administrator supposed to keep track of the various applications and services running across several different domains and servers? Currently, there are a few known existing resources and/or tools available that would be able to assist with monitoring as well as proactively...
