I am looking through the documentation on Splunk about trendlines and sma | ema | wma. In the documentation, it says you must pick an integer between 2 and 1000:

https://docs.splunk.com/Documentation/Splunk/7.3.2/SearchReference/Trendline

| trendline sma2(muffins) as trend

The documentation doesn't say what the period means, but you have to pick a number between 2 and 1000. I assuming "2" is one day, "3" is two days???

| streamstats count
| fields count number
| fields - _time
| trendline sma2(number) sma5(number) sma10(number)

Hi, As you can see from the results, period is not limited to time.
