conf files are scattered all over the directory structure in many similarly-named. Splunk uses configuration files for almost all the settings within it. The above example works fine for basic search problems, but for Enterprise problems, you are going to need some more powerful tools in your toolbox. Then unravel the problematic line piece by piece until you find the problem. Then remove lines of SPL and add them back one line at a time and find the line where the problem shows up. – Have I added a lookup file or event type incorrectly?.– What is the exact thing I am searching for and what is the time range?.You also have access to the search.log link on the far right which opens the search.log where you can search for errors and warnings which may give a clue as to the search issue you are experiencing.īut for more complex SPL (Search Programming Language) problems, ask yourself some basic questions: RunDuration: Time in seconds that the search took to complete. IsFinalized: Indicates if the search was finalized (stopped before completion). IsFailed: Indicates if there was a fatal error executing the search. IsDone: Indicates if the search has completed. eventCount: The number of events returned by the search.ĮventFieldCount: The number of fields found in the search results.ĮventIsTruncated: Indicates that events have not been stored and not available for search.The most important fields for troubleshooting are the following: The Search Job Properties section contains a list of many fields with additional search parameters. You can narrow down which processing components are impacting the search performance. With the information in the Execution Costs section, you can troubleshoot the efficiency of your search. – The input and output event counts for each component.– How many times each component was invoked while the search ran.The Execution Costs section lists information about the components of the search and how much impact each component has on the overall performance of the search. Also note the amount of time it took to complete the search, which may be a symptom of a problem you are not even aware of yet! You can access the Job Inspector by clicking the dropdown to the left of the search mode.įrom the dropdown, select “Inspect Job.” You will see another screen containing Execution Costs details and Search Job Properties details. The Search Job Inspector is a tool that lets you take a closer look at what your search is doing and see where the Splunk software is spending most of its time.

The first tool you will need for troubleshooting basic searching problems is the Splunk Search Job Inspector. How many times have you run a search and said to yourself, “Where are all my fields?” We quickly learned to check the search modem and make sure if you want fields to be in Verbose mode or to a lesser extent Smart mode. Some problems we see over and over and have learned to do a couple of simple checks to solve the problem. The first tool need you will as you begin your Splunk troubleshooting journey is some basic knowledge on how to troubleshoot and how to narrow down all the possibilities, like peeling off layers of an onion until eventually you find the root cause of the problem. Understanding what tools are available to fix and troubleshoot common Splunk Enterprise problems and how to use those tools - at a macro level - is the purpose of this blog. Without the correct tools for the job, many tasks simply could not be accomplished - or at least would become much more difficult and time-consuming. Whereas the expert has many tools which have been refined over many years of experience fixing many problems. The novice has almost no tools in their toolbox, and the tools that they have are large and clunky. Like many things in life, having the right tools to fix a problem is what separates the novice from the expert. By: David Allen | Senior Splunk Consultant
