Microsoft Patch Tuesday! Are your servers patched?
It’s my most favorite time of the month – Patch Tuesday! Ok, I might be slightly exaggerating there. Let’s face it. It’s a pain in the neck. I have to go around to every server in my development environment and ensure that all the critical patches have been taken care of. Usually, this means a trip to Windows Update, or checking the logs of the Windows Server Update Services (WSUS) server. Today, I woke up and decided Splunk was going to assist with this.
Enabling Real-Time Backfill
The funny thing about Splunk is how it just doesn’t stop surprising you. Even after years of using it, you still get surprises. Okay, I must confess I haven’t used Splunk for years, but you get the idea.
Last week, I was in the land of Kimchis in a -5 degrees Celsius (23 degrees Fahrenheit) room, wearing no gloves and a thin veil as my underwear. It was brutal as usual, especially when you are not in your own country. I was thumbing thru the Splunk User’s manual trying to look for some answers. Out of the corner of my eye, I saw a few paragraphs that were new to me. In fact, there were so new that I…
The effective security buyer
Sometimes I’m glad I keep around the mounds of free trade publications that tend to pile up on my desk. About once a month I start going through the stack but I never quite finish. I got through placing 4 or 5 publications into the recycling bin before I read How to be an effective security buyer by Andreas M. Antonopoulos in the May 2011 on-line edition of Network World. This article (more than others I’ve read) takes a basic and practical approach to the hard buying decisions (and trade-offs) we all have to make. The buying decision criteria is crisp and fresh and discourages simply relying on vendors that would…
Maintaining State of the Union
Well, it’s almost that time of year again already – the State of the Union address is scheduled for January 25th, 2011.
- Things are getting better :]
- There are still many challenges to overcome :[

However, I would actually like to discuss a different kind of “state” – one that is more directly related to Splunk’s built-in capabilities (though I haven’t given up on…
Astronomy and Summary Indexing
I had the pleasure last week of viewing Saturn’s rings at Rutgers University’s observatory. It was my first time actually seeing the rings through a professional telescope and the planet does look like what we often see in text book pictures. After the viewing, I started thinking that astronomy records a lot of data that needs to be indexed for search and aggregated for reports. I asked the professor conducting the tour if he had any logs for astrometry data and he took out his paper notebook to show it to me. Obviously, in Splunk terms, that was not what I was asking to see.
In seriousness, the professor told me that optical telescopes, radio telescopes, and spectrometers can generate…
Quick Splunk Reference for SQL Users
If you are familiar with SQL and think in SQL, this quick comparison might be helpful for you to dive into the Splunk search language. Splunk is not a database, in the normative sense, but there are enough similar concepts between the Splunk and the database worlds that this quickstart makes sense.
Universally Indexing Business Data
By the title of this entry, you may be thinking that there is some new capability within Splunk to index other types of data. That’s not the intention. From its roots, Splunk was used to index and search on IT data. It still is. However, because of the flexible nature of the software to index any type of time series text data, customers using Splunk do not restrict it to indexing only IT data. From the beginning Splunk was designed to universally index data from a variety of sources as long as the data was eventually ASCII text in representation.
Due to this inherent capability, Splunk can index data that is not necessarily meant for consumption by IT staff and…
