Using Raw Data Sizing and Custom Search Base These searches use the len Splunk. Could you please have a look at my query and let me know where I'm going wrong and what I could do to avoid using a join command: However, I'm not sure it's working correctly. Or, in the other words you can say it’s giving the last value in the raw field. ![]() Based on this join, I want to return results from both searches only in instances where ITEM values match. Explanation: We have used stats last (raw), which is giving the last event or the bottom event from the event list. I'm using the join command to join to searches based on a common field called ITEM. The subsearch is *not* hitting any limits on execution time or number of results the overall data set is fairly small. sourcetypeaccess stats count (eval (method'GET')) AS GET, count (eval (method'POST')) AS POST BY host. Run the following search to use the command to determine the number of different page requests, GET and POST, that occurred for each Web server. ![]() I am sure this is something simple that I have overlooked, but I don't see it! I've even looked at the Search Job Inspector, but nothing shows up there either. get the tutorial data into Splunk when you run the search. For example, the second search gave an average of 45453.56 while the first search gave an average of 42823.32638888889. I am using the standard access_combined sourcetype for this example, so clientip is the IP address that is connecting to the Apache server, status is the HTTP status code, and bytes is the number of bytes in the HTTP request.īut the searches give slightly different results. (My real search is slightly different, but this illustrates the problem perfectly.) Successful traffic is defined as status=400. The concept of both searches is the same: Identify IPs that have had HTTP errors in the previous week, and summarize the number of bytes of "successful" traffic, average and median during that timeframe. | stats sum(bytes) as bytes count(eval(check="Bad")) as Bad by clientip Explanation: We have used stats last (raw), which is giving the last event or the bottom event from the event list. Index=web sourcetype=access_combined action=purchase **Option 2: using an eval to replace the subsearch** The eventstats command lets us add statistics to every row, without. | stats avg(bytes) as avg_bytes, median(bytes) as median_bytes Index=web sourcetype=access_combined status=400 The difference is that with the eventstats command aggregation results are added inline to each event and added only if the aggregation is pertinent to that event.Īnd here is a blog which will tell you the extact difference between themHere are two searches, which I think are logically equivalent, yet they return different results in Splunk. The eventstats command is similar to the stats command. If you use a by clause one row is returned for each distinct value specified in the by clause.Įventstats - Generate summary statistics of all existing fields in your search results and saves those statistics in to new fields. What are stats command in Splunk The statistics commands are used to calculate summary statistics on the search results from events retrieved from an index. If stats is used without a by clause only one row is returned, which is the aggregation over the entire incoming result set. Stats - Calculates aggregate statistics over the results set, such as average, count, and sum.
