[google-cloud-monitoring] cannot create log-based alerting policy

[cjroebuck]

Environment details

• which product (packages/*): google-cloud-monitoring
• OS: mac / not relevant
• Node.js version: 18
• npm version: 9.5.1
• google-cloud-node version: 3.0.4

Steps to reproduce

const createAlertInGcp = async () => {
  const alertPolicy: google.monitoring.v3.AlertPolicy = {
    displayName: "Timed out (api)",
    documentation: {
      content:
        "${log.extracted_label.user}'s request timed out.\n\nIt happened in ${resource.labels.cluster_name}. The url was ${log.extracted_label.url}",
      mimeType: "text/markdown",
    },
    conditions: [
      {
        displayName: "Timed out (api)",
        conditionMatchedLog: {
          filter:
            'resource.type="k8s_container"\nresource.labels.namespace_name="default"\nresource.labels.container_name="engine"\njsonPayload.message=~"Timed out"\njsonPayload.msg="Returning a 500 error"',
          labelExtractors: {
            user: "EXTRACT(jsonPayload.options.user)",
            url: "EXTRACT(jsonPayload.options.url)",
          },
        },
      },
    ],
    alertStrategy: {
      notificationRateLimit: {
        period: "3600s",
      },
      autoClose: "1800s",
    },
    combiner: "OR",
    enabled: { value: true },
    notificationChannels: [
      "projects/project/notificationChannels/1209803...",
    ],
  };
  const alertPolicyRequest: google.monitoring.v3.ICreateAlertPolicyRequest = {
    name: client.projectPath(projectId),
    alertPolicy,
  };
  // client.create
  let res = await client.createAlertPolicy(alertPolicyRequest);
  console.log(res);

The error in the response is:

'Field alert_policy.conditions[0].condition_case had an invalid value of "0": Condition subtype (e.g. "condition_absent","condition_threshold", etc.) is absent or unknown.',

So it seems that the conditionMatchedLog subtype is not supported yet by the nodejs client, only the metric-based alerts seem to be supported.

Following this: https://cloud.google.com/monitoring/alerts/policies-in-api#log-polices

and this: https://cloud.google.com/logging/docs/alerting/log-based-alerts#lba-api-create

it does seem to be supported through the API using the gcloud cli.

Having the exact same issue. Are there any updates?

Im using google-cloud-node version: 4.0.0

[gregfenton]

Have the exact same issue today. Any update? Is it simply not possible currently to create a conditionMatchedLog alert via the NodeJS API ?

I tried getting the JSON from an existing alert, using the API to delete that alert, and then recreate it (removing the fields name, creationRecord, mutationRecord just like the example docs indicate). The existing alert is deleted, but the exact same error as the OP occurs when it tries to create the alert.

Calling CREATE with: {
  name: 'projects/sales-demo-1',
  alertPolicy: {
    alertStrategy: {
      autoClose: '604800s',
      notificationRateLimit: { period: '3600s' }
    },
    combiner: 'OR',
    conditions: [
      {
        displayName: 'Log match condition',
        conditionMatchedLog: { filter: 'textPayload=~"Function execution took ((?:\\d[,.]?)*\\d) ms, finished with status: ' }
      }
    ],
    displayName: 'SALES-DEMO-1 Non-OK Cloud Functions',
    notificationChannels: [
      'projects/sales-demo-1/notificationChannels/4444444444444444444',
      'projects/sales-demo-1/notificationChannels/7666666666666666665',
      'projects/sales-demo-1/notificationChannels/7888888888888888886'
    ]
  }
}
node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^

Node.js v18.17.1

The code for this is available here, though it is just a tweaked version of an example from the docs.
