Use steamstats instead of eventstats command. If we want to see results in streaming manner, use streamstats command.ġ. We can see that the original bytes field is retained. Sourcetype=access_combined* | head 10 | eventstats sum(bytes) as ATotalBytes by clientip | Use table command to see clientip, bytes and AtotalBytes Sourcetype=access_combined* | head 10 | eventstats sum(bytes) as ATotalBytes by clientip|Ģ. If we want to retain the original field as well, use eventstats command. Notice that the bytes column is empty above, because once the table is created by the stats command, Splunk now knows nothing about the original bytes field. Sourcetype=access_combined* | head 10 | stats sum(bytes) as ATotalBytes by clientip | table Use Table to See original filed name (bytes) Sourcetype=access_combined* | head 10 | stats sum(bytes) as ATotalBytes by clientipģ. Compute the sum of the bytes for each clientip. Search for the top 10 events from the web log.Ģ. The stats command calculates statistics based on fields in your events.ġ. To begin, do a simple search of the web logs in Splunk and look at 10 events and the associated byte count related to ip addresses in the field clientip. Let’s take an example to understand this better. The total is calculated by using the values in the specified field for every event that has been processed, up to the current event. For example, you can calculate the running total for a particular field. The streamstats command calculates statistics for each event at the time the event is seen. Streamstats adds cumulative summary statistics to all search results in a streaming manner. 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. 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 generates summary statistics of all existing fields in your search results and saves those statistics in to new fields. 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. This commands are helpful in calculations like count, max, average, etc. In most of the complex queries written in splunk stats, eventstats and streamstats commands are widely used.
