Event Information

  • The google.monitoring.v3.NotificationChannelService.UpdateNotificationChannel event in GCP for Monitoring refers to the update or modification of a notification channel configuration.
  • This event indicates that changes have been made to the settings of a notification channel, such as updating the delivery endpoint, changing the notification preferences, or modifying the channel’s display name.
  • It is important to monitor this event to track any changes made to the notification channels in order to ensure that the desired alerting and notification configurations are maintained accurately.

​
Examples

  • Unauthorized access: If the google.monitoring.v3.NotificationChannelService.UpdateNotificationChannel API is not properly secured, it could potentially allow unauthorized users to update or modify notification channels. This could lead to unauthorized access to sensitive information or the ability to disrupt monitoring and alerting systems.

  • Data leakage: If the API is misconfigured or lacks proper access controls, it could result in the exposure of sensitive information related to notification channels. This could include email addresses, phone numbers, or other contact information associated with the channels. Such data leakage could violate privacy regulations and compromise the security of affected individuals or organizations.

  • Denial of Service (DoS) attacks: If the API is vulnerable to DoS attacks, an attacker could potentially flood the service with a high volume of requests, overwhelming the system and causing it to become unresponsive. This could result in a disruption of monitoring and alerting capabilities, potentially leading to delayed or missed notifications for critical events.

Remediation

​
Using Console

  1. Enable GCP Monitoring:
  • Log in to the GCP Console.
  • Navigate to the Monitoring page.
  • Click on “Enable Monitoring” to enable monitoring for your GCP resources.
  1. Set up Monitoring Alerts:
  • In the GCP Console, go to the Monitoring page.
  • Click on “Create Alerting Policy” to create a new alerting policy.
  • Define the conditions for the alert based on the specific event you want to monitor.
  • Specify the notification channels to receive alerts (e.g., email, SMS, etc.).
  • Save the alerting policy.
  1. Configure Monitoring Dashboards:
  • In the GCP Console, go to the Monitoring page.
  • Click on “Create Dashboard” to create a new dashboard.
  • Add the relevant charts and metrics to the dashboard based on the events you want to monitor.
  • Customize the layout and appearance of the dashboard as per your preference.
  • Save the dashboard for future reference.

Note: These steps provide a high-level overview of how to remediate the issues using GCP Monitoring. The actual steps may vary depending on the specific event and requirements. It is recommended to refer to the official GCP documentation for detailed instructions.

​
Using CLI

  1. Enable GCP Monitoring for a project:
  • Use the gcloud command to enable GCP Monitoring for a specific project: 
    gcloud services enable monitoring.googleapis.com --project [PROJECT_ID]
  1. Create a custom metric in GCP Monitoring:
  • Use the gcloud command to create a custom metric: 
    gcloud alpha monitoring metrics create [METRIC_NAME] \
--display-name="[DISPLAY_NAME]" \
--description="[DESCRIPTION]" \
--project=[PROJECT_ID]
  1. Create an alert policy in GCP Monitoring:
  • Use the gcloud command to create an alert policy: 
    gcloud alpha monitoring policies create [POLICY_NAME] \
--display-name="[DISPLAY_NAME]" \
--condition="[CONDITION]" \
--project=[PROJECT_ID]

​
Using Python

To remediate GCP Monitoring issues using Python, you can utilize the following approaches:

  1. Automating resource creation and configuration:

    • Use the Google Cloud Client Library for Python to programmatically create and configure monitoring resources such as uptime checks, alerting policies, and dashboards.
    • Example script: 
      from google.cloud import monitoring_v3

def create_uptime_check(project_id, display_name, http_check):
    client = monitoring_v3.UptimeCheckServiceClient()
    parent = client.project_path(project_id)
    check = monitoring_v3.UptimeCheckConfig(display_name=display_name, http_check=http_check)
    response = client.create_uptime_check_config(parent, check)
    print('Uptime check created:', response)

create_uptime_check('your-project-id', 'My Uptime Check', {'host': 'example.com', 'path': '/'})

  2. Implementing automated alerting:

    • Use the Google Cloud Pub/Sub client library for Python to publish alert notifications to a Pub/Sub topic.
    • Example script: 
      from google.cloud import pubsub_v1

def publish_alert(project_id, topic_name, message):
    publisher = pubsub_v1.PublisherClient()
    topic_path = publisher.topic_path(project_id, topic_name)
    data = message.encode('utf-8')
    future = publisher.publish(topic_path, data)
    print('Alert published:', future.result())

publish_alert('your-project-id', 'my-topic', 'High CPU utilization detected!')

  3. Creating custom monitoring metrics:

    • Use the Google Cloud Monitoring API to create custom metrics and collect specific data points from your applications or services.
    • Example script: 
      from google.cloud import monitoring_v3

def create_custom_metric(project_id, metric_type, metric_kind, value_type):
    client = monitoring_v3.MetricServiceClient()
    project_name = client.project_path(project_id)
    metric_descriptor = monitoring_v3.types.MetricDescriptor()
    metric_descriptor.type = f'custom.googleapis.com/{metric_type}'
    metric_descriptor.metric_kind = metric_kind
    metric_descriptor.value_type = value_type
    response = client.create_metric_descriptor(project_name, metric_descriptor)
    print('Custom metric created:', response)

create_custom_metric('your-project-id', 'my_custom_metric', 'GAUGE', 'DOUBLE')
