![]() If you use a wildcard for the value, NOT fieldA=* returns events where fieldA is null or undefined, and fieldA!=* never returns any events. The following search returns events where fieldA exists and does not have the value "value2". The following search returns everything except fieldA="value2", including all other fields. This will be a key position on our Applied Cybersecurity team which is a very tight-knit and important team working on an international mission. Searching with the boolean "NOT" comparison operator is not the same as using the "!=" comparison. SUMMARY: The Power BI SME With cyber combines a true expertise in PowerBI and the Power Platform with experience in Azure Security, Microsoft Defender and Microsoft Sentinel. Search sourcetype=access_combined_wcookie action IN (addtocart, purchase) 5. Use the eval command with mathematical functions. In the events from an access.log file, search the action field for the values addtocart or purchase. ![]() This example shows how to use the IN operator to specify a list of field-value pair matchings. Search host=webserver* status IN(4*, 5*) 4. Click your name on the navigation bar and select Preferences. ![]() Search host=webserver* (status=4* OR status=5*)Īn alternative is to use the IN operator, because you are specifying two field-value pairs on the same field. Click the refresh button on your browser and ensure that your name now appears in the Splunk bar. This example searches for events from all of the web servers that have an HTTP client and server error status. 1 Answer Sorted by: 2 The construct foo bar means 'show events where the 'foo' field does not have the value 'bar'. This example shows field-value pair matching with wildcards. Search (code=10 OR code=29 OR code=43) host!="localhost" xqp>5Īn alternative is to use the IN operator, because you are specifying multiple field-value pairs on the same field. This example searches for events with code values of either 10, 29, or 43 and any host that is not "localhost", and an xqp value that is greater than 5. This example shows field-value pair matching with boolean and comparison operators. This example shows field-value pair matching for specific values of source IP (src) and destination IP (dst). 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. Complex queries involve the pipe character, which feeds the output of the previous query into the next. To learn more about the search command, see How the search command works. Splunk uses what’s called Search Processing Language (SPL), which consists of keywords, quoted phrases, Boolean expressions, wildcards (), parameter/value pairs, and comparison expressions. Begin by specifying the data using the parameter index, the equal sign, and the data index of your choice: indexindexofchoice. The following are examples for using the SPL2 search command.
