A condition is a true/false test that determines when an alerting policy should open an incident. If a condition evaluates to true, it signifies that something is wrong.
A short name or phrase used to identify the condition in dashboards, notifications, and incidents. To avoid confusion, don't use the same display name for multiple conditions in the same policy.
A condition that compares a time series against a threshold.
Classes
MetricAbsence
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 duration
.
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
resrouces). Multiple aggregations are applied in the order
specified. This field is similar to the one in the
`ListTimeSeries
request
</monitoring/api/ref_v3/rest/v3/projects.timeSeries/list>__.
It is advisable to use the
ListTimeSeries` method when
debugging this field.
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
.
MetricThreshold
A condition type that compares a collection of time series against a threshold.
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
resrouces). Multiple aggregations are applied in the order
specified. This field is similar to the one in the
`ListTimeSeries
request
</monitoring/api/ref_v3/rest/v3/projects.timeSeries/list>__.
It is advisable to use the
ListTimeSeries` method when
debugging this field.
Specifies the alignment of data points in individual time
series selected by denominatorFilter
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). When computing ratios,
the aggregations
and denominator_aggregations
fields
must use the same alignment period and produce time series
that have the same periodicity and labels.
A value against which to compare the time series.
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
, or by the ratio, if
denominator_filter
and denominator_aggregations
are
specified.
Trigger
Specifies how many time series must fail a predicate to trigger a
condition. If not specified, then a {count: 1}
trigger is used.
The absolute number of time series that must fail the predicate for the condition to be triggered.
