Google Cloud Trigger

Google Cloud Trigger
Certified
Trigger on Cloud Monitoring results

Polls Cloud Monitoring every interval (default 60s) with the filter over window (default 5m). Starts a Flow execution when at least one time series is found and exposes series and count in the trigger output. Requires Monitoring access on the target project; supports custom service accounts and scopes.

type: io.kestra.plugin.gcp.monitoring.Trigger

Examples

Trigger when a Cloud Monitoring query returns non-empty results

yaml
id: gcp_monitoring_trigger
namespace: company.team
tasks:
  - id: each
    type: io.kestra.plugin.core.flow.ForEach
    values: "{{ trigger.series }}"
    tasks:
      - id: log
        type: io.kestra.plugin.core.log.Log
        message: "Metric: {{ fromJson(taskrun.value) }}"

triggers:
  - id: watch
    type: io.kestra.plugin.gcp.monitoring.Trigger
    interval: "PT1M"
    projectId: "gcp-project-id"
    filter: 'metric.type="compute.googleapis.com/instance/cpu/utilization" AND resource.type="gce_instance"'
    window: PT5M

Properties

filter *string

Filter expression

Cloud Monitoring filter string evaluated each poll; the trigger fires only when it returns at least one time series

allowConcurrent boolean

Defaultfalse

Specifies whether a trigger is allowed to start a new execution even if a previous run is still in progress.

interval string

DefaultPT1M

Formatduration

Polling interval

Duration between query runs; defaults to 60 seconds

projectId string

Project ID

Google Cloud project that holds the monitored metrics

scopes array

SubTypestring

Default["https://www.googleapis.com/auth/cloud-platform"]

OAuth scopes

Scopes used when building credentials; defaults to https://www.googleapis.com/auth/cloud-platform

serviceAccount string

Service account

Optional service account email to authenticate the Monitoring client; falls back to application default credentials

stopAfter array

SubTypestring

Possible Values

CREATEDSUBMITTEDRUNNINGPAUSEDRESTARTEDKILLINGSUCCESSWARNINGFAILEDKILLEDCANCELLEDQUEUEDRETRYINGRETRIEDSKIPPEDBREAKPOINTRESUBMITTED

List of execution states after which a trigger should be stopped (a.k.a. disabled).

when string

Defaulttrue

A condition that determines whether the trigger should run.

A Pebble expression evaluated at trigger time. The trigger fires only when the expression evaluates to a truthy value (true, a non-empty string, a non-zero number). Use this to gate trigger execution on dynamic runtime values such as execution labels, flow variables, or environment conditions.

window string

DefaultPT5M

Query window

Lookback duration for the filter; defaults to 5 minutes

Outputs

count integer

Total number of time series fetched

Count of time series returned by the Cloud Monitoring query

series array

SubTypeobject

List of time series

Raw Cloud Monitoring time series in JSON form
