![]() ![]() To be explained in a simpler manner, the count field will count 1 for the first event and 2 for the second event and so on… This example adds a count field to each event that represents the total number of fields until now, including the recent event too. …| streamstats avg(field1) BY field2 window=10 global=f This example computes the average of a field with a specific condition but over the last 10 events as we have discussed earlier. So for each event, we are going to compute the average of the specific field field1 over the last 10 events This example computes the average of a field over the last 10 events. Let us now look at the theory we have just discussed in the section above in the form of examples and let us understand the nitty gritty details that we might have missed exploring earlier. Let us look at some examples with Splunk Streamstats: The function can also be applied to an evaluation of an expression (using the eval command), or to any number of field(s). We should be using the AS clause to place the result that has been obtained until this point into another new field with a name that you specify or mention. This is well described as a statistical aggregation function. The stats command will work on a group of results as a whole instead of all search results as such.įrequently Asked Splunk Interview Questions ![]() In streamstats command, the calculation of the summary statistics is performed on all the search results unlike the case with stats command. The streamstats command is also similar in comparison with the stats command. If there is a need for us to include the current even into the statistical calculations as well, then the expression current = true can be used (which is always the default condition). The streamstats command is very much similar in comparison with the eventstats command with the only difference being that it uses events before the current event to compute the aggregate statistics that are applied to each event. The value will be calculated as the sum of the values for each processed event until the current event. As an example, the running total of a specific field can be calculated using this command without any hassles. This command calculates the statistics for each event when it is observed. Splunk software provides a command named streamstats that adds all the cumulative summary statistics to all search results in a streaming or a cumulative manner. ![]()
