![]() Splunk Enterprise To change the max_mem_usage_mb setting, follow these steps. Otherwise, contact Splunk Customer Support. If you have a support contract, file a new case using the Splunk Support Portal at Support and Services. Splunk Cloud Platform To change the max_mem_usage_mb setting, request help from Splunk Support. When the limit is reached, the eventstats command processor stops adding the requested fields to the search results.ĭo not set max_mem_usage_mb=0 as this removes the bounds to the amount of memory the eventstats command processor can use. The eventstats search processor uses a nf file setting named max_mem_usage_mb to limit how much memory the eventstats command can use to keep track of information. The eventstats command is a dataset processing command. For an overview about using functions with commands, see Statistical and charting functions. Use the links in the table to see descriptions and examples for each function. The following table lists the supported functions by type of function. Each time you invoke the eventstats command, you can use one or more functions. Description: Statistical and charting functions that you can use with the eventstats command. Stats function options stats-func Syntax: The syntax depends on the function that you use. ![]() Default: false Syntax: BY Description: The name of one or more fields to group by. If you have a BY clause, the allnum argument applies to each group independently. Optional arguments allnum Syntax: allnum= Description: If set to true, computes numerical statistics on each field, if and only if ,all of the values of that field are numerical. You can use wild card characters in field names. Use the AS clause to place the result into a new field with a name that you specify. The function can be applied to an eval expression, or to a field or set of fields. ![]() Required arguments Syntax: ( | ) Description: A statistical aggregation function. The generated summary statistics can be used for calculations in subsequent commands in your search. Only those events that have fields pertinent to the aggregation are used in generating the summary statistics. The result shows the mean and variance of the values of the field named bytes in rows organized by the http status values of the events.Generates summary statistics from fields in your events and saves those statistics in a new field. We continue using the same fields as shown in the previous examples. In the below example, we use the functions mean() & var() to achieve this. Statistically focused values like the mean and variance of fields is also calculated in a similar manner as given above by using appropriate functions with the stats command. We continue the previous example but instead of average, we now use the max(), min() and range function together in the stats command so that we can see how the range has been calculated by taking the difference between the values of max and min columns. The stats command can be used to display the range of the values of a numeric field by using the range function. In the below example, we find the average byte size of the files grouped by the various http status code linked to the events associated with those files. But with a by clause, it will give multiple rows depending on how the field is grouped by the additional new field. Without a BY clause, it will give a single record which shows the average value of the field for all the events. This function takes the field name as input. We can find the average value of a numeric field by using the avg() function. If a BY clause is used, one row is returned for each distinct value specified in the BY clause.īelow we see the examples on some frequently used stats command. If the stats command is used without a BY clause, only one row is returned, which is the aggregation over the entire incoming result set. ![]() ![]() The stats command works on the search results as a whole and returns only the fields that you specify.Įach time you invoke the stats command, you can use one or more functions. The stats command is used to calculate summary statistics on the results of a search or the events retrieved from an index. ![]()
