Works best when the search includes the sort command immediately before the statistics or charting command.

To locate the last value based on time order, use the latest function instead.

The last seen value of the field is the oldest instance of this field, based on the order in which the events are seen by the stats command. When you add the first function to the search, the only value returned is the value in the field you specify: The first result was processed first (20-1=19) followed by the remaining results in order. This shows the order in which the results were processed. Use the eval command to add a field to your search results with values in descending order:Īs you can see from the results, the first result contains the highest number in field1. The hours in the results begin with the 1 hour earlier than the original date, at 14:24. The minutes and seconds in the search results are slightly different because the timestamp is refreshed each time you run the search. The result is subtracted from the original _time field to get new dates equivalent to 1 hours ago, 2 hours ago, and so forth. The calculation multiplies the value in the count field by the number of seconds in an hour.

Splunk transaction time series#

Use 3600, the number of seconds in an hour, to create a series of hours. With the count field, you can create different dates in the _time field, using the eval command.

Include the streamstats command to count your results: To add a timestamp to the events, use the eval command with the now() time modifier. You can use the repeat dataset function to create a series of results to test your search syntax. However, you can use the first function on any field. That's useful because the _raw field contains a timestamp. The Basic example uses the _raw field to show how the first function works. The search returns the value for _raw field with the timestamp 00:15:05, which is the first event in the original list of values returned. You extend the search using the first function.

You run the following search to locate invalid user login attempts against a specific sshd (Secure Shell Daemon).

This function processes field values as strings.

The first functions works best when the search includes the sort command immediately before the statistical or charting command.

To locate the first value based on time order, use the earliest function instead.

You can use this function with the stats, streamstats, and timechart commands. The order in which the events are seen is not necessarily chronological order.

The first seen value is the most recent instance of this field, based on the order in which the events are seen by the stats command. This event is both the chronologically earliest event and the last event in the search results. This event is chronologically the latest event in the search results. But this event is not chronologically the earliest event. This event is the first event in the search results. This table identifies which event is returned when you use the first and last event order functions, and compares them with the earliest and latest time functions. The following table lists the timestamps from a set of events returned from a search. Use the event order functions to return values from fields based on the order in which the event is processed, which is not necessarily chronological or timestamp order.įor an overview of the stats functions, seeĬhronological and timestamp order distinction
