A condition type that checks that monitored resources are reporting
data. The configuration defines a metric and a set of monitored
resources. The predicate is considered in violation when a time
series for the specified metric of a monitored resource does not
include any data in the specified
Required. A `filter
Specifies the alignment of data points in individual time series as well as how to combine the retrieved time series together (such as when aggregating multiple streams on each resource to a single stream for each resource or when aggregating streams across all members of a group of resources). Multiple aggregations are applied in the order specified. This field is similar to the one in the ```ListTimeSeries`` request
The amount of time that a time series must fail to report new data to be considered failing. The minimum value of this field is 120 seconds. Larger values that are a multiple of a minute--for example, 240 or 300 seconds--are supported. If an invalid value is given, an error will be returned. The ``Duration.nanos`` field is ignored.
The number/percent of time series for which the comparison must hold in order for the condition to trigger. If unspecified, then the condition will trigger if the comparison is true for any of the time series that have been identified by ``filter`` and ``aggregations``.
