Additionally, a well-implemented monitoring strategy facilitates data-driven decision-making, enabling organizations to make informed adjustments to their infrastructure or applications.

Ultimately, the implementation of a comprehensive monitoring strategy is integral to achieving operational excellence, ensuring customer satisfaction, and supporting the overall success of an organization.

Use full-stack monitoring

Full-stack monitoring is a complete approach to monitoring, triaging, and diagnosing application, infrastructure, and security issues. Full-stack monitoring includes telemetry collection, tracking key performance indicators, isolating problems, and analyzing root causes.

Your applications and infrastructure might face different kinds of potentially damaging issues, such as poor response times, changing usage rates, exceptions, and security risks. Your response must be appropriate to the issue type. You might respond by scaling up capacity to meet increased load, or by changing your application or infrastructure to improve performance and reduce errors.

With the right tools, you can:

• Monitor your infrastructure and application performance.
• Monitor for security risks and suspicious activity.
• Collect information on issues as soon as they arise.
• Analyze and respond to the information you collect.

By monitoring your applications and infrastructure with a full-stack approach, you respond to changes and issues quickly and appropriately. This strategy can help your organization become more productive, cost-effective, secure, and competitive.

Monitor your applications

To maintain the health of your application, monitor it during development to catch errors early and ensure successful code checks before advancing to the next stage. Ongoing monitoring during live usage helps identify issues like failing requests, high response times, and availability problems, enabling prompt and effective responses to keep the application healthy.

Implementing alerts and automated responses enhances the application’s overall health and contributes to the development of better applications in the future.

Monitor your infrastructure

Different kinds of issues that can affect infrastructure, such as performance issues or service unavailability, leading to productivity loss and reputational damage. To address these issues effectively, the suggestion is to configure alerts for monitoring different aspects of infrastructure, including:

• Your infrastructure’s resource utilization.
• Your infrastructure’s availability and health.
• A specific event occurring at the operating-system level.

These alerts can prompt human intervention or trigger automated responses through playbooks and webhooks. Additionally, infrastructure monitoring data can be utilized for operational analysis and capacity planning by collecting performance data for comparison and trend analysis to inform decision-making.

Monitor security

Monitoring the security of both applications and infrastructure is a crucial aspect of maintaining continuous protection and availability. This involves a vigilant watch over potential vulnerabilities and threats that could compromise the security of the system.

Specifically, it is recommended to keep a close eye on:

• Data exfiltration: Unauthorized data transfer outside the system.
• Risks to infrastructure security: Such as suspicious user accounts or malicious IP addresses.

A robust security monitoring solution is necessary for effective surveillance. This solution should incorporate:

• Advanced and automated anomaly detection capabilities: Identifying deviations from normal patterns of behavior.
• Efficient event management system: Correlating and consolidating multiple related events into a single actionable alert.

Monitoring options in Azure

Azure Monitor

Azure Monitor is a service for collecting, analyzing, and acting on telemetry from your cloud and on-premises environments. You can analyze metrics and logs from monitored resources.

Key components and features of Azure Monitor include:

1. Metrics:

• Azure Monitor collects metrics, which are numerical values that represent various aspects of the performance and health of resources. These metrics can include CPU usage, memory usage, disk I/O, network latency, and more.
• Metrics are collected at regular intervals and can be used to create charts, set up alerts, and analyze trends over time.

2. Logs:

• Azure Monitor collects logs, which are detailed records of events and activities from resources. These logs can include information from the operating system, applications, Azure services, and custom sources.
• Logs are stored in Azure Monitor Log Analytics, which allows for advanced querying, analysis, and visualization of log data.

Azure Monitor Log Analytics workspaces are central repositories for log data collected from various sources across the Azure environment. These workspaces play a crucial role in Azure’s monitoring and management capabilities, providing a unified platform for storing, analyzing, and visualizing log data.

3. Alerts:

• Azure Monitor allows you to set up alerts based on defined conditions for metrics or log data. When the conditions are met, alerts can trigger notifications to inform administrators or automated systems about potential issues.
• Alerts help organizations proactively respond to problems and ensure the availability and reliability of their applications.

4. Application Insights:

• Application Insights is a part of Azure Monitor that focuses on application performance monitoring. It helps developers and IT teams identify and diagnose performance issues in applications.
• It provides insights into application dependencies, user interactions, error rates, and more. This information is valuable for optimizing application performance and user experience.

5. Workbooks:

• Azure Monitor Workbooks allow users to create and share interactive, customizable dashboards. These dashboards can combine data from various sources, including metrics, logs, and external data, to provide a holistic view of the environment.

6. Azure Monitor for Containers:

• This feature is designed to monitor containerized applications deployed on Azure Kubernetes Service (AKS) or other container orchestration platforms. It provides visibility into the performance and health of containers and orchestrators.

You can integrate Prometheus with Grafana in Azure Monitor by using Azure Monitor managed service for Prometheus as a data source for Grafana. This allows you to collect and analyze metrics at scale using a Prometheus-compatible monitoring solution. The most common way to analyze and present Prometheus data is with a Grafana dashboard. You can configure Prometheus as a data source for both Azure Managed Grafana and self-hosted Grafana running in an Azure virtual machine using managed system identity authentication.
