Moving Average Simple Aggregation Usage
editMoving Average Simple Aggregation Usage
editFluent DSL example
edita => a .DateHistogram("projects_started_per_month", dh => dh .Field(p => p.StartedOn) .Interval(DateInterval.Month) .MinimumDocumentCount(0) .Aggregations(aa => aa .Sum("commits", sm => sm .Field(p => p.NumberOfCommits) ) .MovingAverage("commits_moving_avg", mv => mv .BucketsPath("commits") .Window(30) .Predict(10) .GapPolicy(GapPolicy.InsertZeros) .Model(m => m .Simple() ) ) ) )
Object Initializer syntax example
editnew DateHistogramAggregation("projects_started_per_month") { Field = "startedOn", Interval = DateInterval.Month, MinimumDocumentCount = 0, Aggregations = new SumAggregation("commits", "numberOfCommits") && new MovingAverageAggregation("commits_moving_avg", "commits") { Window = 30, Predict = 10, GapPolicy = GapPolicy.InsertZeros, Model = new SimpleModel() } }
Example json output.
{ "projects_started_per_month": { "date_histogram": { "field": "startedOn", "interval": "month", "min_doc_count": 0 }, "aggs": { "commits": { "sum": { "field": "numberOfCommits" } }, "commits_moving_avg": { "moving_avg": { "buckets_path": "commits", "model": "simple", "window": 30, "predict": 10, "gap_policy": "insert_zeros", "settings": {} } } } } }
Handling Responses
editresponse.ShouldBeValid(); var projectsPerMonth = response.Aggregations.DateHistogram("projects_started_per_month"); projectsPerMonth.Should().NotBeNull(); projectsPerMonth.Buckets.Should().NotBeNull(); projectsPerMonth.Buckets.Count.Should().BeGreaterThan(0); // average not calculated for the first bucket so movingAvg.Value is expected to be null there foreach (var item in projectsPerMonth.Buckets.Skip(1)) { var movingAvg = item.Sum("commits_moving_avg"); movingAvg.Should().NotBeNull(); movingAvg.Value.Should().BeGreaterThan(0); }
