Hello, and welcome to the debut of Smart AnSwerS, a weekly blog series featuring posts from Splunk Answers on trending issues, interesting use cases, and more!

For the last couple of months, I’ve been reviewing incoming content on Answers and selecting high-value postings to summarize and email weekly to my compadres on the mighty Splunk Support team. Pretty quickly, we realized that this information wasn’t just useful to Support–it is useful to everyone who uses Splunk–so here we are. This first installment is a bit of a best-of from the previous emails, but look for a new blog post each week chock full of specially-curated Answers for you to expand your brainmeats with.

Answers? What’s that?

If you aren’t familiar with Splunk Answers, it serves as the Q&A forum for Splunk users to find, well, answers to their common and not-so-common questions about deploying, managing, and using Splunk products. Contributors of all backgrounds and levels of expertise come to the site seeking solutions to their head-scratchers, and to help others tackle their own Splunk puzzlers.

You’re the Answer

Something important to remember: all of you who use Splunk products every day in the real world have a vast array of knowledge to share with the rest of our community–Splunk employees and customers alike! We’re all learning a great deal from each other to use and improve our products, so let’s keep up the great work :)

So without further ado, check out the first set of featured Answers posts:

How to compare fields over multiple sourcetypes without join, append, or use of subsearches?

A question I find often throughout Answers is how search performance is affected by certain commands and approaches such as join, append and subsearches. MuS provides run anywhere examples and utilizes other search commands that return the same results more efficiently. Other Answers users have definitely deemed this post bookmark-worthy for reference:

How do optimizations for field-based searches work?

This post serves as a great education piece on how Splunk retrieves events for field-based searches. Hexx and jrodman tag team to highlight the various scenarios and factors that determine how these searches are executed to return events. Check it out to learn or to refresh your memory on the logic of search-time configurations, lookups, regex-based field extractions, and more:

How to sort data in chronological order by month, not alphabetically?

A common problem I’ve seen on Answers is users needing to sort data in chronological order by month or day of the week, not alphabetically by the name of the month or day. Splunk does not inherently understand how to sort in this manner. In this post, Ayn explains a solution to this by creating a numerical field to associate with each month to sort by and get the user’s expected result.
