Splunk base search11/23/2023 For example, if your post-process search will search for the top-selling buttercup game categories over time, you would use a search command similar to the following: | fields _time, categoryId, action If the base search is a non-transforming search, you must explicitly state in the base search what fields will be used in the post-process search using the | fields command. If you observe these issues in a dashboard, check the base search to make sure that it is a transforming search. Non-transforming base searches can cause the following search result and timeout issues. A base search should be a transforming search that returns results formatted as a statistics table. Use these Splunk best practices to make sure that post-process searches work as expected. You can use a single post-process search to generate results or you can chain multiple post-process searches together. Use the base attribute in a post-process to indicate the base search id. A base search can be a global search or any other search within a dashboard. Post-process searches perform additional processing on results from a base search. This is where post-process searching can help you optimize your dashboards. Or you may reference the same root search but transform variances of fields with different stats counts across your panels. When you or your users are developing dashboards, you may notice a lot of the panels reference the same root search, but you may display the data in different charts (like the same data visualized in a timechart as well as a single value). How do I know if I can use post process searching? Enabling your users will absolutely do wonders for getting your environment to run smoothly. First, is the impact of hardware allocation. There are two major hindrances to Splunk performance. This is a critical technique for your Splunk users to learn, especially as your Splunk environment grows and you have more and more people using resources for alerts, adhoc searches, dashboards, and more. So we can potentially cut the count of individual searches firing in a dashboard by 30-40% (or higher in some cases). Post-process searching can help with this problem by applying a single common base search across multiple dashboard panels. Especially if it is a widely used dashboard and multiple people are opening it at the same time. So, when you have a dashboard that could have 15, 25, or even 30 panels on it, you can see how this would be extremely resource-intensive. A general rule of thumb with Splunk is: every search running at a time is taking up a single CPU on the server for processing. Post-process searching is a technique used to optimize dashboards in Splunk.
