Advanced queries

There are various kinds of advanced query that you may want to consider as you plan out how you will create searches and dashboards for your data. Consider the ones that we present, for they will help you design queries that are more efficient and cost effective.

Subsearch

A subsearch is a search within a search. If your main search requires data as a result of another search, then you can use Splunk's subsearch capability to achieve it. Say you want to find statistics about the server that generates the most 500 errors. A 500 error is a general HTTP status code that means that something has gone wrong with the server, but it doesn't know specifically at this particular time what is wrong. Obviously, if you are responsible for running a website, you want to pay close attention to 500 errors and where they are coming from. You can achieve your goal of finding the culprit server with two searches.

The first search, shown next, will return the server address with the...
