Reference documentation and code samples for the Cloud Monitoring Dashboards V1 API module Google::Cloud::Monitoring::Dashboard::V1::Aggregation::Reducer.
A Reducer operation describes how to aggregate data points from multiple time series into a single time series, where the value of each data point in the resulting series is a function of all the already aligned values in the input time series.
Constants
REDUCE_NONE
value: 0
No cross-time series reduction. The output of the Aligner
is returned.
REDUCE_MEAN
value: 1
Reduce by computing the mean value across time series for each alignment period. This reducer is valid for [DELTA][google.api.MetricDescriptor.MetricKind.DELTA] and [GAUGE][google.api.MetricDescriptor.MetricKind.GAUGE] metrics with numeric or distribution values. The value_type
of the output is [DOUBLE][google.api.MetricDescriptor.ValueType.DOUBLE].
REDUCE_MIN
value: 2
Reduce by computing the minimum value across time series for each alignment period. This reducer is valid for DELTA
and GAUGE
metrics with numeric values. The value_type
of the output is the same as the value_type
of the input.
REDUCE_MAX
value: 3
Reduce by computing the maximum value across time series for each alignment period. This reducer is valid for DELTA
and GAUGE
metrics with numeric values. The value_type
of the output is the same as the value_type
of the input.
REDUCE_SUM
value: 4
Reduce by computing the sum across time series for each alignment period. This reducer is valid for DELTA
and GAUGE
metrics with numeric and distribution values. The value_type
of the output is the same as the value_type
of the input.
REDUCE_STDDEV
value: 5
Reduce by computing the standard deviation across time series for each alignment period. This reducer is valid for DELTA
and GAUGE
metrics with numeric or distribution values. The value_type
of the output is DOUBLE
.
REDUCE_COUNT
value: 6
Reduce by computing the number of data points across time series for each alignment period. This reducer is valid for DELTA
and GAUGE
metrics of numeric, Boolean, distribution, and string value_type
. The value_type
of the output is INT64
.
REDUCE_COUNT_TRUE
value: 7
Reduce by computing the number of True
-valued data points across time series for each alignment period. This reducer is valid for DELTA
and GAUGE
metrics of Boolean value_type
. The value_type
of the output is INT64
.
REDUCE_COUNT_FALSE
value: 15
Reduce by computing the number of False
-valued data points across time series for each alignment period. This reducer is valid for DELTA
and GAUGE
metrics of Boolean value_type
. The value_type
of the output is INT64
.
REDUCE_FRACTION_TRUE
value: 8
Reduce by computing the ratio of the number of True
-valued data points to the total number of data points for each alignment period. This reducer is valid for DELTA
and GAUGE
metrics of Boolean value_type
. The output value is in the range [0.0, 1.0] and has value_type
DOUBLE
.
REDUCE_PERCENTILE_99
value: 9
Reduce by computing the 99th percentile of data points across time series for each alignment period. This reducer is valid for GAUGE
and DELTA
metrics of numeric and distribution type. The value of the output is DOUBLE
.
REDUCE_PERCENTILE_95
value: 10
Reduce by computing the 95th percentile of data points across time series for each alignment period. This reducer is valid for GAUGE
and DELTA
metrics of numeric and distribution type. The value of the output is DOUBLE
.
REDUCE_PERCENTILE_50
value: 11
Reduce by computing the 50th percentile of data points across time series for each alignment period. This reducer is valid for GAUGE
and DELTA
metrics of numeric and distribution type. The value of the output is DOUBLE
.
REDUCE_PERCENTILE_05
value: 12
Reduce by computing the 5th percentile of data points across time series for each alignment period. This reducer is valid for GAUGE
and DELTA
metrics of numeric and distribution type. The value of the output is DOUBLE
.
