Metric Aggregations:
|
|
|
|
*Count*:: The {ref}/search-aggregations-metrics-valuecount-aggregation.html[_count_] aggregation returns a raw count of
|
|
the elements in the selected index pattern.
|
|
*Average*:: This aggregation returns the {ref}/search-aggregations-metrics-avg-aggregation.html[_average_] of a numeric
|
|
field. Select a field from the drop-down.
|
|
*Sum*:: The {ref}/search-aggregations-metrics-sum-aggregation.html[_sum_] aggregation returns the total sum of a numeric
|
|
field. Select a field from the drop-down.
|
|
*Min*:: The {ref}/search-aggregations-metrics-min-aggregation.html[_min_] aggregation returns the minimum value of a
|
|
numeric field. Select a field from the drop-down.
|
|
*Max*:: The {ref}/search-aggregations-metrics-max-aggregation.html[_max_] aggregation returns the maximum value of a
|
|
numeric field. Select a field from the drop-down.
|
|
*Unique Count*:: The {ref}/search-aggregations-metrics-cardinality-aggregation.html[_cardinality_] aggregation returns
|
|
the number of unique values in a field. Select a field from the drop-down.
|
|
*Standard Deviation*:: The {ref}/search-aggregations-metrics-extendedstats-aggregation.html[_extended stats_]
|
|
aggregation returns the standard deviation of data in a numeric field. Select a field from the drop-down.
|
|
*Percentiles*:: The {ref}/search-aggregations-metrics-percentile-aggregation.html[_percentile_] aggregation divides the
|
|
values in a numeric field into percentile bands that you specify. Select a field from the drop-down, then specify one
|
|
or more ranges in the *Percentiles* fields. Click the *X* to remove a percentile field. Click *+ Add* to add a
|
|
percentile field.
|
|
*Percentile Rank*:: The {ref}/search-aggregations-metrics-percentile-rank-aggregation.html[_percentile ranks_]
|
|
aggregation returns the percentile rankings for the values in the numeric field you specify. Select a numeric field
|
|
from the drop-down, then specify one or more percentile rank values in the *Values* fields. Click the *X* to remove a
|
|
values field. Click *+Add* to add a values field.
|

Parent Pipeline Aggregations:
|
|
|
|
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
|
|
(for example to produce 3rd derivative)
|
|
|
|
*Derivative*:: The {ref}/search-aggregations-pipeline-derivative-aggregation.html[_derivative_] aggregation calculates
|
|
the derivative of specific metrics.
|
|
*Cumulative Sum*:: The {ref}/search-aggregations-pipeline-cumulative-sum-aggregation.html[_cumulative sum_] aggregation
|
|
calculates the cumulative sum of a specified metric in a parent histogram
|
|
*Moving Average*:: The {ref}/search-aggregations-pipeline-movavg-aggregation.html[_moving average_] aggregation will
|
|
slide a window across the data and emit the average value of that window
|
|
*Serial Diff*:: The {ref}/search-aggregations-pipeline-serialdiff-aggregation.html[_serial differencing_] is a technique
|
|
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
|
|
|
|
*Average Bucket*:: The {ref}/search-aggregations-pipeline-avg-bucket-aggregation.html[_avg bucket_]
|
|
calculates the (mean) average value of a specified metric in a sibling aggregation
|
|
*Sum Bucket*:: The {ref}/search-aggregations-pipeline-avg-bucket-aggregation.html[_sum bucket_]
|
|
calculates the sum of values of a specified metric in a sibling aggregation
|
|
*Min Bucket*:: The {ref}/search-aggregations-pipeline-avg-bucket-aggregation.html[_min bucket_]
|
|
calculates the minimum value of a specified metric in a sibling aggregation
|
|
*Max Bucket*:: The {ref}/search-aggregations-pipeline-avg-bucket-aggregation.html[_max bucket_]
|
|
calculates the maximum value of a specified metric in a sibling aggregation
|
|
|
|
You can add an aggregation by clicking the *+ Add Metrics* button.

Enter a string in the *Custom Label* field to change the display label.
