Ciscos second largest campus in the United States is located at. 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. Over 15,000 full-time employees are based at the San Jose campus and the surrounding Bay Area. 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. Splunk, only named capturing groups must be used to extract data into fields.

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. If you want to extract a different number of fractional seconds, use the SUBDT. Events with the same JSESSIONID will be grouped together into a single event.

But with a by clause, it will give multiple rows depending on how the field is grouped by the additional new field. An additional field named eventcount is created. 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. The users are turned into a field by using the rex filedraw command. Suppose I have a log file that has 2 options for the field host: host-a, host-b and 2 different users.

I've got a question about how to group things, below. 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. Hi I'm a new user and have begun using this awesome tool. 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.
