The order of the values reflects the order of input events. e. You can use both SPL2 commands and SPL command functions in the same search. You can go on to analyze all subsequent lookups and filters. When you specify report_size=true, the command. A new field is added all 4events and the aggregation is added to that field in every event. Please try to keep this discussion focused on the content covered in this documentation topic. Examples of streaming searches include searches with the following commands: search, eval,. The eventcount command just gives the count of events in the specified index, without any timestamp information. For each hour, calculate the count for each host value. Example 2 shows how to find the most frequent shopper with a subsearch. With the GROUPBY clause in the from command, the <time> parameter is specified with the <span-length> in the span function. This example sorts the results first by the lastname field in ascending order and then by the firstname field in descending order. This eval expression uses the pi and pow. It is faster and consumes less memory than stats command, since it using tsidx and is effective to build. See Command types.
