Using Azure To Monitor Your Applications Health and Costs

As more organisations are moving their workloads to the cloud, it is essential to monitor the performance and availability of their applications and control the budget. Microsoft Azure provides a range of tools to help developers and IT professionals monitor their applications’ health and costs, including Azure Alerts, Azure Application Insights, Azure Dashboards and Azure Budgets. In this article, we will discuss how to use Azure to monitor your applications and receive customized alerts.


Azure Application Insights is a service that helps you monitor the performance and usage of your applications. It does this by collecting telemetry data, including metrics, logs and traces. You can use Application Insights to gain insights into how your application is performing and identify issues that may be impacting your users’ experience, creating Azure Alerts based on the collected data.

Application Insights provides other features including, but not limited to:

  • Live Metrics: Observe activity from your deployed application in real-time with no effect on the host environment
  • Availability: Also known as synthetic transaction monitoring. Probe the external endpoints of your applications to test the overall availability and responsiveness of your app over time
  • GitHub or Azure DevOps integration: Create GitHub or Azure DevOps work items in the context of Application Insights data
  • Usage: Understand which features are popular with users and how users interact and use your application
  • Smart detection: Detect failures and anomalies automatically through proactive telemetry analysis


Azure Alerts is a service that helps you monitor the health of your Azure resources by automatically sending email and/or SMS notifications when a specified condition is met. You can set up alerts for various metrics, including CPU usage, memory usage and network traffic. Plus, you can create further customised alerts like application errors and volume of requests.

The following diagram shows how alerts work.

  • Azure Resources – sends telemetry data from Apps, Database, Functions and other resources to Azure Application Insights.
  • Alert Rules – User set up rules based on telemetry collected.
  • Fired Alerts – Alerts are triggered based on alert Rules when condition Met
  • Actions – When the user set up the rules, they can set up actions, it can include:
    • Notification methods, such as email, SMS, and push notifications
    • Automation runbooks
    • Azure functions
    • ITSM incidents
    • Logic apps
    • Secure webhooks
    • Webhooks
    • Event hubs


Azure Dashboard is a web-based tool that allows you to create interactive and customisable dashboards to monitor and analyse your Azure resources. With Azure Dashboards, you can collect data from various sources, including Azure Application Insights, Azure Monitor, Azure Resource Graph, and Azure Log Analytics. As well as create charts, tables, and visualizations. Together you gain insight into the performance of your resources and troubleshooting errors.

Budgets within Cost Management help you plan for and drive organisational accountability. They help you proactively inform others about their spending in order to manage costs and monitor how spending progresses over time.

You can configure alerts based on your actual cost or forecasted cost to ensure that your spending is within your organisational spending limit. Notifications are triggered when the budget thresholds you’ve created are exceeded. None of your resources are affected, and your consumption isn’t stopped. You can use budgets to compare and track spending as you analyse costs.

In the following example, an email alert gets generated when 90% of the budget is reached.


By setting up Azure Alerts, using Azure Application Insights with Azure Dashboards and creating budgets, you can monitor the health of your applications, gain insights into how they are performing and manage your costs. This can help you identify issues and take action to resolve them before they impact your users’ experience and your expenditure. If you are new to Azure, we recommend exploring these tools and learning more about how they can help you manage your cloud-based workloads.

Microsoft Teams is constantly evolving. Microsoft released its new, improved version back in October 2023 – and from the end of June, only the new Teams will be available. So, if you haven’t already switched or don’t yet know about new Teams, now is the time to start.

Before diving into the transformative world of Copilot for Microsoft 365, it's crucial to prepare your systems and data to harness its full potential.
