This advanced certification test assesses a candidate’s knowledge and abilities in advanced searching and reporting commands, advanced knowledge of object use cases, and best practices for dashboard and form creation. Alternatively, the maximum results and the maximum runtime parameters may be increased.Splunk Core Certified Advanced Power User examination is developed as a component of the certification. The best option is to rewrite the query in order to limit the number of events the sub search will have to process. In large manufacturing environments, the sub search in this example may be time-out before it is complete. Sub-searches can return a maximum of 10,000 results by default and have a maximum runtime of 60 seconds. The top Command will have to keep track of all those addresses before returning the top 1 with an impactful performance if there are thousands of separate IP addresses. Note: This sub searches performance depends on how many distinct IP addresses match status=200 AND action = purchase. If we run it at the same time range, these results will match the results of the two searches in Example 1 If we adjust the time period, we may see different outcomes as it would be different for the top purchasing customers. Here, in this code, because the top Command returns the fields of count and percent, the table command retains only the clientip value. Sourcetype=access_* status=200 action=purchase | stats count, distinct_count(productId), values(productId) by clientip Now, copy and paste the search below into the search bar and run the search in the editor.In Splunk, a sub search is enclosed in square brackets and evaluated first when reading the search criteria.
Because we are searching the same data, the beginning of the external search is identical to the beginning of the sub search. The purchase search is referred to as the outer or primary search. The most frequent shopper search becomes the sub search for the purchase search. We provide the result of the most common search for shoppers as one of the search criteria for the purchases. We run a search on the same data to see what the shopper has ordered.
Because with the table command, we specified only the clientip field, that is the only field that was returned.įrom the output, the count and percent fields produced by the top Command are discarded. The difference is the last piped instruction, table clientip, which shows the details about the clientip in a row. This search is nearly identical to the search in step 1 of Example 1. Here, this search returns the clientip, clientip=87.194.216.51, for the most frequent shopper.
