What is the difference between stats eventstats streamstats?

[maitrifer]

Hi All I'm new to Splunk and I'm confused between stats eventstats and streamstats. Can anyone help me to understand?

stats

Stats calculate aggregate statistics over the dataset, similar to SQL aggregation. If called without a by clause, one row is produced, which represents the aggregation over the entire incoming result set. 

eventstats

Eventstats calculates a statistical result same as stats command only difference is it does not create statistical results, it aggregates them to the original raw data.

streamstats

Streamstats command uses events before the current event to compute the aggregate statistics that are applied to each event.

One addition to streamstats, you could define the window which it use to calculate stats. Also you could define some conditions dynamically for window. There are some cases where this is mandatory to get correct result. https://docs.splunk.com/Documentation/Splunk/8.0.5/SearchReference/Streamstats

Hi
Here is one explanation https://splunkonbigdata.com/2018/09/29/difference-between-streamstats-and-eventstats-command-in-splu.... Shortly streamstats calculate over sliding window and eventstats over all values.

stats replaces the pipleline  - only calculated values based all the data in the pipeline are passed down the line

eventstats adds to the pipeline as a whole - calculated values are based on all the data in the pipeline and added as additional fields to the rows passed down the line

streamstats adds to the pipeline as it passes through - calculated values are based on the data received so far
