Search commands help filter unwanted events, extract additional information, calculate values, transform data, and statistically analyze the indexed data. Here is an example of an event in a web activity log: It can be a text document, configuration file, or entire stack trace. Unless you’re joining two explicit Boolean expressions, omit the AND operator because Splunk assumes the space between any two search terms to be AND.īasic Search offers a shorthand for simple keyword searches in a body of indexed data myIndex without further processing:Īn event is an entry of data representing a set of values associated with a timestamp. Splunk uses what’s called Search Processing Language (SPL), which consists of keywords, quoted phrases, Boolean expressions, wildcards (*), parameter/value pairs, and comparison expressions. The Search Head is for searching, analyzing, visualizing, and summarizing your data.The Forwarder (optional) sends data from a source.The Indexer parses and indexes data added to Splunk.Splunk contains three processing components: Splunk Enterprise search results on sample data
With Splunk, not only is it easier for users to excavate and analyze machine-generated data, but it also visualizes and creates reports on such data. The Internet of Things (IoT) and Internet of Bodies (IoB) generate much data, and searching for a needle of datum in such a haystack can be daunting.
