Updates an alerting policy. You can either replace the entire policy with a new one or replace only certain fields in the current alerting policy by specifying the fields to be updated via updateMask. Returns the updated alerting policy.Design your application to single-thread API calls that modify the state of alerting policies in a single project. This includes calls to CreateAlertPolicy, DeleteAlertPolicy and UpdateAlertPolicy.

Scopes

You will need authorization for at least one of the following scopes to make a valid call:

  • https://www.googleapis.com/auth/cloud-platform
  • https://www.googleapis.com/auth/monitoring

If unset, the scope for this method defaults to https://www.googleapis.com/auth/cloud-platform. You can set the scope for this method like this: monitoring3 --scope <scope> projects alert-policies-patch ...

Required Scalar Argument

  • <name> (string)
    • Required if the policy exists. The resource name for this policy. The format is: projects/[PROJECT_ID_OR_NUMBER]/alertPolicies/[ALERT_POLICY_ID] [ALERT_POLICY_ID] is assigned by Cloud Monitoring when the policy is created. When calling the alertPolicies.create method, do not include the name field in the alerting policy passed as part of the request.

Required Request Value

The request value is a data-structure with various fields. Each field may be a simple scalar or another data-structure. In the latter case it is advised to set the field-cursor to the data-structure's field to specify values more concisely.

For example, a structure like this:

AlertPolicy:
  alert-strategy:
    auto-close: string
    notification-rate-limit:
      period: string
  combiner: string
  creation-record:
    mutate-time: string
    mutated-by: string
  display-name: string
  documentation:
    content: string
    mime-type: string
    subject: string
  enabled: boolean
  mutation-record:
    mutate-time: string
    mutated-by: string
  name: string
  notification-channels: [string]
  severity: string
  user-labels: { string: string }
  validity:
    code: integer
    message: string

can be set completely with the following arguments which are assumed to be executed in the given order. Note how the cursor position is adjusted to the respective structures, allowing simple field names to be used most of the time.

  • -r .alert-strategy auto-close=ea
    • If an alert policy that was active has no data for this long, any open incidents will close

  • notification-rate-limit period=ipsum

    • Not more than one notification per period.

  • ... combiner=invidunt

    • How to combine the results of multiple conditions to determine if an incident should be opened. If condition_time_series_query_language is present, this must be COMBINE_UNSPECIFIED.
  • creation-record mutate-time=amet
    • When the change occurred.

  • mutated-by=duo

    • The email address of the user making the change.

  • .. display-name=ipsum

    • A short name or phrase used to identify the policy in dashboards, notifications, and incidents. To avoid confusion, don't use the same display name for multiple policies in the same project. The name is limited to 512 Unicode characters.The convention for the display_name of a PrometheusQueryLanguageCondition is "{rule group name}/{alert name}", where the {rule group name} and {alert name} should be taken from the corresponding Prometheus configuration file. This convention is not enforced. In any case the display_name is not a unique key of the AlertPolicy.
  • documentation content=sed
    • The body of the documentation, interpreted according to mime_type. The content may not exceed 8,192 Unicode characters and may not exceed more than 10,240 bytes when encoded in UTF-8 format, whichever is smaller. This text can be templatized by using variables (https://cloud.google.com/monitoring/alerts/doc-variables).
  • mime-type=ut
    • The format of the content field. Presently, only the value "text/markdown" is supported. See Markdown (https://en.wikipedia.org/wiki/Markdown) for more information.

  • subject=gubergren

    • Optional. The subject line of the notification. The subject line may not exceed 10,240 bytes. In notifications generated by this policy, the contents of the subject line after variable expansion will be truncated to 255 bytes or shorter at the latest UTF-8 character boundary. The 255-byte limit is recommended by this thread (https://stackoverflow.com/questions/1592291/what-is-the-email-subject-length-limit). It is both the limit imposed by some third-party ticketing products and it is common to define textual fields in databases as VARCHAR(255).The contents of the subject line can be templatized by using variables (https://cloud.google.com/monitoring/alerts/doc-variables). If this field is missing or empty, a default subject line will be generated.

  • .. enabled=true

    • Whether or not the policy is enabled. On write, the default interpretation if unset is that the policy is enabled. On read, clients should not make any assumption about the state if it has not been populated. The field should always be populated on List and Get operations, unless a field projection has been specified that strips it out.
  • mutation-record mutate-time=ipsum
    • When the change occurred.

  • mutated-by=ipsum

    • The email address of the user making the change.

  • .. name=est

    • Required if the policy exists. The resource name for this policy. The format is: projects/[PROJECT_ID_OR_NUMBER]/alertPolicies/[ALERT_POLICY_ID] [ALERT_POLICY_ID] is assigned by Cloud Monitoring when the policy is created. When calling the alertPolicies.create method, do not include the name field in the alerting policy passed as part of the request.
  • notification-channels=gubergren
    • Identifies the notification channels to which notifications should be sent when incidents are opened or closed or when new violations occur on an already opened incident. Each element of this array corresponds to the name field in each of the NotificationChannel objects that are returned from the ListNotificationChannels method. The format of the entries in this field is: projects/[PROJECT_ID_OR_NUMBER]/notificationChannels/[CHANNEL_ID]
    • Each invocation of this argument appends the given value to the array.
  • severity=ea
    • Optional. The severity of an alert policy indicates how important incidents generated by that policy are. The severity level will be displayed on the Incident detail page and in notifications.
  • user-labels=key=dolor
    • User-supplied key/value data to be used for organizing and identifying the AlertPolicy objects.The field can contain up to 64 entries. Each key and value is limited to 63 Unicode characters or 128 bytes, whichever is smaller. Labels and values can contain only lowercase letters, numerals, underscores, and dashes. Keys must begin with a letter.Note that Prometheus {alert name} is a valid Prometheus label names (https://prometheus.io/docs/concepts/data_model/#metric-names-and-labels), whereas Prometheus {rule group} is an unrestricted UTF-8 string. This means that they cannot be stored as-is in user labels, because they may contain characters that are not allowed in user-label values.
    • the value will be associated with the given key
  • validity code=45
    • The status code, which should be an enum value of google.rpc.Code.
  • message=eos
    • A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client.

About Cursors

The cursor position is key to comfortably set complex nested structures. The following rules apply:

  • The cursor position is always set relative to the current one, unless the field name starts with the . character. Fields can be nested such as in -r f.s.o .
  • The cursor position is set relative to the top-level structure if it starts with ., e.g. -r .s.s
  • You can also set nested fields without setting the cursor explicitly. For example, to set a value relative to the current cursor position, you would specify -r struct.sub_struct=bar.
  • You can move the cursor one level up by using ... Each additional . moves it up one additional level. E.g. ... would go three levels up.

Optional Output Flags

The method's return value a JSON encoded structure, which will be written to standard output by default.

  • -o out
    • out specifies the destination to which to write the server's result to. It will be a JSON-encoded structure. The destination may be - to indicate standard output, or a filepath that is to contain the received bytes. If unset, it defaults to standard output.

Optional Method Properties

You may set the following properties to further configure the call. Please note that -p is followed by one or more key-value-pairs, and is called like this -p k1=v1 k2=v2 even though the listing below repeats the -p for completeness.

  • -p update-mask=string
    • Optional. A list of alerting policy field names. If this field is not empty, each listed field in the existing alerting policy is set to the value of the corresponding field in the supplied policy (alert_policy), or to the field's default value if the field is not in the supplied alerting policy. Fields not listed retain their previous value.Examples of valid field masks include display_name, documentation, documentation.content, documentation.mime_type, user_labels, user_label.nameofkey, enabled, conditions, combiner, etc.If this field is empty, then the supplied alerting policy replaces the existing policy. It is the same as deleting the existing policy and adding the supplied policy, except for the following: The new policy will have the same [ALERT_POLICY_ID] as the former policy. This gives you continuity with the former policy in your notifications and incidents. Conditions in the new policy will keep their former [CONDITION_ID] if the supplied condition includes the name field with that [CONDITION_ID]. If the supplied condition omits the name field, then a new [CONDITION_ID] is created.
