• Container Insights: Provides detailed insights into Kubernetes Engine workloads.

Example

gcloud monitoring channels create   --display-name="Slack Channel"   --type="slack"   --channel-labels=webhook_url="https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX"

3. Microsoft Azure Monitor

Azure Monitor maximizes the availability and performance of applications and services on Azure.

Features

• Comprehensive Data Collection: Collects metrics, logs, and traces from Azure resources.
• Actionable Insights: Uses artificial intelligence to detect anomalies and forecast trends.
• Application Monitoring: Application Insights provides deep diagnostics for applications.

Use Cases

• Performance Optimization: Analyze resource utilization and performance bottlenecks.
• Security Monitoring: Track and respond to security threats across Azure services.

Example

{
  "name": "alertRule1",
  "description": "CPU percentage on VM",
  "isEnabled": true,
  "condition": {
    "odata.type": "Microsoft.Azure.Management.Insights.Models.ThresholdRuleCondition",
    "dataSource": {
      "odata.type": "Microsoft.Azure.Management.Insights.Models.RuleMetricDataSource",
      "resourceUri": "/subscriptions/{subscription-id}/resourceGroups/{resource-group}/providers/Microsoft.Compute/virtualMachines/{vm-name}",
      "metricName": "Percentage CPU"
    },
    "operator": "GreaterThan",
    "threshold": 90
  },
  "action": {
    "odata.type": "Microsoft.Azure.Management.Insights.Models.RuleEmailAction",
    "sendToServiceOwners": true
  }
}

4. Datadog

Datadog is a cloud-native monitoring and analytics platform for infrastructure, applications, and logs.

Features

• Unified Platform: Combines real-time monitoring, alerting, and data visualization.
• Integrations: Over 400 integrations with cloud providers, automation tools, and more.
• Machine Learning: Anomaly detection and forecasting with machine learning models.

Use Cases

• Full-Stack Visibility: Monitor everything from infrastructure metrics to application logs.
• Enhanced Collaboration: Share dashboards and alerts across teams for improved coordination.

Example

init_config:

instances:

logs:
  - type: file
    path: /var/log/myapp.log
    service: myapp
    source: myapp

5. Prometheus

An open-source monitoring solution designed for reliability and scalability, Prometheus is widely used for cloud-native environments.

Features

• Time-series Database: Stores metrics in a highly efficient time-series database.
• Powerful Query Language: PromQL allows for complex queries and aggregations.
• Alertmanager: Handles alerts generated by Prometheus queries.

Use Cases

• Kubernetes Monitoring: Integrated seamlessly with Kubernetes for container monitoring.
• Microservices Architecture: Ideal for monitoring distributed microservices.

Example

global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['localhost:9090']
