Parent Pipeline Aggregations:
|
|
|
|
|
2017-06-27 19:13:42 +02:00
|
|
|
For each of the parent pipeline aggregations you have to define the metric for which the aggregation is calculated.
|
|
|
|
That could be one of your existing metrics or a new one. You can also nest this aggregations
|
2017-04-25 08:01:02 +02:00
|
|
|
(for example to produce 3rd derivative)
|
|
|

|
2017-06-27 19:13:42 +02:00
|
|
|
*Derivative*:: The {ref}/search-aggregations-pipeline-derivative-aggregation.html[_derivative_] aggregation calculates
|
2017-04-25 08:01:02 +02:00
|
|
|
the derivative of specific metrics.
|
2017-06-27 19:13:42 +02:00
|
|
|
*Cumulative Sum*:: The {ref}/search-aggregations-pipeline-cumulative-sum-aggregation.html[_cumulative sum_] aggregation
|
2017-04-25 08:01:02 +02:00
|
|
|

|
2017-06-27 19:13:42 +02:00
|
|
|
*Moving Average*:: The {ref}/search-aggregations-pipeline-movavg-aggregation.html[_moving average_] aggregation will
|
2017-04-25 08:01:02 +02:00
|
|
|
slide a window across the data and emit the average value of that window
|
2017-06-27 19:13:42 +02:00
|
|
|
*Serial Diff*:: The {ref}/search-aggregations-pipeline-serialdiff-aggregation.html[_serial differencing_] is a technique
|
2017-04-25 08:01:02 +02:00
|
|
|
where values in a time series are subtracted from itself at different time lags or period

Sibling Pipeline Aggregations:
|
|
|
|
|
|
|
|
Just like with parent pipeline aggregations you need to provide a metric for which to calculate the sibling aggregation.
|
|
|
|
On top of that you also need to provide a bucket aggregation which will define the buckets on which the sibling
|
|
|
|
aggregation will run
|
|
|

|
2017-06-27 19:13:42 +02:00
|
|
|
*Sum Bucket*:: The {ref}/search-aggregations-pipeline-avg-bucket-aggregation.html[_sum bucket_]
|
2017-04-25 08:01:02 +02:00
|
