Tutorial / Cram Notes
Azure Monitor is a comprehensive solution that collects, analyzes, and acts on telemetry from cloud and on-premises environments. It helps to understand how applications are performing and proactively identifies issues affecting them and the resources they depend on.
To set up alerts in Azure Monitor, you can follow these steps:
- Navigate to the Azure portal.
- Search for and select “Monitor.”
- In the Monitor pane, select “Alerts” from the left-hand menu.
- Click on “+ New alert rule.”
From here, you will need to configure the alert criteria:
- Target Resource: Specify the Azure resource you want to monitor.
- Criteria: Define the conditions that will trigger the alert. This could be metrics like CPU usage, or events such as an Azure service health incident.
- Action Group: Select an existing action group or create a new one. The action group determines what actions are taken when the alert is triggered.
- Alert Details: Provide a name for the alert rule and, optionally, a description.
Action Groups
When an alert is triggered, Azure can perform actions such as sending emails, SMS messages, calling a webhook, or executing an Azure Function. These actions are encapsurated in an action group. To create an action group:
- In the Monitor pane, select “Action groups” from the left-hand menu.
- Click on “+ New action group.”
- Fill in the action group details, such as the subscription, resource group, name, and a short name for the action group.
In the action group, you can configure several types of actions, a few include:
- Email/SMS/Push/Voice: Send notifications to the relevant parties via their preferred method.
- Function App: Trigger an Azure Function to execute custom code.
- Logic App: Start an Azure Logic App workflow.
- Webhook: Send an HTTP POST payload to the specified URL.
Azure Automation Runbooks
Beyond notifications, Azure allows for automated responses through the use of Azure Automation Runbooks. For example, if a Virtual Machine is experiencing high CPU usage, a Runbook could be configured to restart the VM.
Here is a simple flow for setting up a Runbook action:
- Create or select an existing Automation Account.
- Within the account, define a Runbook with the script for the remediation task.
- Link the Runbook to the action group associated with the alert.
Comparison of Action Types
| Action Type | Use Case |
|---|---|
| Email/SMS/Push/Voice | Notify stakeholders of incidents |
| Azure Function | Execute custom code for complex actions |
| Logic App | Automate workflows with multiple steps |
| Webhook | Integrate with external services |
| Automation Runbook | Automated remediation tasks |
Best Practices
- Define meaningful alert names and descriptions to quickly identify the purpose and scope of the alert.
- Use appropriate metrics or logs for alert criteria based on the sensitivity and criticality of resources.
- Ensure action groups are kept up-to-date, especially contact details in notifications.
- Test your alerts and actions to confirm they operate as expected.
Networking Monitoring Tools
Azure provides several tools specifically for monitoring the health and connectivity of network resources. Network Watcher is one such tool that provides the ability to diagnose network performance and health. Features like NSG Flow Logs, Traffic Analytics, and Connection Monitor offer detailed insights into your network traffic and can be leveraged to trigger alerts and actions as necessary.
Conclusion
Setting up alerts and actions is a vital part of managing Azure resources and ensures you can respond proactively to any issues or incidents. Familiarity with Azure Monitor, Action Groups, and relevant monitoring tools is essential for an Azure Administrator, providing the capabilities required for efficient and effective resource management. Through careful configuration and application of these features, Azure resources can be maintained at optimal levels, adhering to the standards expected in a professionally managed cloud environment.
Practice Test with Explanation
True or False: In Azure Monitor, alerts can be set up based on metrics, logs, or activity log events.
- True
Azure Monitor allows you to create alert rules based on metrics, logs, and activity log events, helping you remain proactive in monitoring the health and performance of your Azure resources.
Which Azure service is primarily used for executing automated actions in response to alerts?
- A) Azure Automation
- B) Azure Functions
- C) Azure Logic Apps
- D) All of the above
D) All of the above
Automated responses to alerts can be executed using Azure Automation, Azure Functions, and Azure Logic Apps, depending on the complexity and requirements of the task.
True or False: It is possible to set up alerts without any action group in Azure.
- True
While action groups are recommended for performing actions in response to alerts, it is possible to set up alerts that just notify without specifying an action group.
Which of the following are valid actions that can be performed by an Azure action group? (Choose all that apply)
- A) Sending an email/SMS/Push/Voice message
- B) Starting an Azure Automation runbook
- C) Automatically scaling a Virtual Machine Scale Set
- D) Generating a storage account access key
A) Sending an email/SMS/Push/Voice message, B) Starting an Azure Automation runbook
Action groups in Azure can perform a variety of actions such as sending notifications and starting an Azure Automation runbook. Automatically scaling a Virtual Machine Scale Set is done by defining autoscale settings, not directly by an action group, and generating a storage account access key is not an action group capability.
True or False: Azure Monitor Logs and Azure Alerts are essentially the same service.
- False
Azure Monitor Logs is a feature within Azure Monitor that collects and organizes log and performance data, while Azure Alerts is a service that notifies users when issues are detected based on metrics or logs data.
Which resource is necessary to send notifications to Azure users when an alert is triggered?
- A) Azure Logic App
- B) Azure Action Group
- C) Azure Event Hub
- D) Azure Notification Hub
B) Azure Action Group
Azure Action Groups are specifically designed to organize the actions and notification scenarios when an alert is triggered in Azure.
True or False: You need to manually configure a new action group for every alert rule you set up in Azure Monitor.
- False
An action group can be reused across multiple alert rules. You do not need to create a new one for every alert; you can assign existing action groups to new alerts.
Which of these resources can you directly monitor with Azure Alerts?
- A) Azure Virtual Machines
- B) Azure Blob Storage
- C) Azure SQL Database
- D) All of the above
D) All of the above
Azure Alerts can be set up for a wide range of Azure services, including Virtual Machines, Blob Storage, and SQL Databases.
True or False: Alerts in Azure Monitor can be created to monitor the health and availability of Azure Active Directory (Azure AD).
- True
Azure Monitor provides capability to monitor the health and availability of various services, including Azure Active Directory.
Which of the following factors should be considered when configuring an alert rule in Azure? (Choose all that apply)
- A) Threshold values
- B) Evaluation frequency
- C) Resource location
- D) Time aggregation type
A) Threshold values, B) Evaluation frequency, D) Time aggregation type
When configuring an alert rule, it is important to set threshold values that define when the alert should fire, choose how frequently the data should be evaluated, and select the type of time aggregation for the metric.
True or False: Azure alerts can only be triggered by high-severity events.
- False
Azure alerts can be configured to be triggered by events of any severity level, as defined by the user’s specified criteria, not just high-severity events.
True or False: When setting up an alert in Azure, you can specify a different action group for each subscription within the same alert rule.
- False
An alert rule is usually scoped to a specific subscription or resource, and a single action group is specified per alert rule; different action groups per subscription within the same alert rule aren’t typically configured. However, you can have different alert rules for different subscriptions each with their own action group.
