Before you can collect any logs, you must create a Log Analytics workspace. This workspace is a unique environment for Azure Monitor Logs where data is collected, aggregated, analyzed, and presented in queries, charts, and alerts.
To create a Log Analytics workspace:
Once a workspace is created, you need to configure data sources. These sources can include Azure virtual machines, Azure resources, and on-premises machines.
To configure data sources for Azure VMs:
To configure data sources for other Azure resources:
After connecting sources, specify which data types to collect. This includes event logs, performance counters, syslogs, and others.
Configure Windows event log data collection:
Configure performance counters:
Log queries are how you extract actionable insights from your data. They use the Kusto Query Language (KQL), which is powerful for analyzing and visualizing data.
Example log query:
Perf
| where ObjectName == “Processor” and CounterName == “% Processor Time” and InstanceName == “_Total”
| summarize AvgCPUUsage=avg(CounterValue) by bin(TimeGenerated, 30m), Computer
| render timechart
This example query collects average CPU usage across all monitored computers, summarized every 30 minutes.
With queries, you can set up alerts to notify you when specific conditions are met.
To create an alert:
Azure Monitor also provides solutions that offer additional insights into your environment. These can be added to your workspace and configured to collect specific data sets.
Example solutions include:
To add a solution:
By configuring Azure Monitor Logs, administrators can get deeper visibility into their environments, which is critical for maintaining operational excellence. This knowledge is integral to the AZ-104 Microsoft Azure Administrator exam, ensuring that candidates understand how to implement, manage, and configure key monitoring aspects of their Azure resources.

Answer: C) Log Analytics Workspace
Explanation: Log Analytics Workspace is the primary repository for storing data in Azure Monitor Logs.
Answer: B) False
Explanation: Azure Monitor can automatically collect platform metrics and logs for many Azure services, with further configuration available for more detailed or custom data collection.
Answer: A) Azure Active Directory, B) Azure HDInsight, C) Azure Cosmos DB
Explanation: Azure Monitor Logs can integrate with a variety of services, including Azure Active Directory, Azure HDInsight, and Azure Cosmos DB, for enhanced logging and monitoring.
Answer: A) True
Explanation: You can export the data from Azure Monitor Logs to Power BI for more advanced visualization and analysis.
Answer: C) Kusto Query Language (KQL)
Explanation: Azure Monitor Logs uses the Kusto Query Language (KQL) for data retrieval and analysis.
Answer: A) True
Explanation: Azure Monitor allows you to create alert rules based on the data from metrics and logs to notify about critical conditions and take automated actions.
Answer: D) To provide insights and analytics for specific applications and services
Explanation: Solutions in Azure Monitor Logs are used to offer insights and analytics tailored to specific applications, workloads, and services.
Answer: B) False
Explanation: Azure Monitor Logs can collect data from resources in multiple Azure regions and pool them into a single Log Analytics Workspace.
Answer: B) Azure VM extension
Explanation: Azure Monitor collects data for Virtual Machines using the Log Analytics agent installed as an extension on Azure VMs.
Answer: A) Visualizing data with workbooks, B) Triggering automated actions using Logic Apps, C) Storing long-term data for compliance
Explanation: With Azure Monitor Logs, you can visualize data with workbooks, trigger automated actions with Logic Apps, and store data long-term for compliance, among other actions. Upgrading VMs is not a direct function of Azure Monitor Logs.
Answer: B) False
Explanation: Once the data in a Log Analytics Workspace is deleted, it is permanently removed and cannot be recovered.
Azure Monitor Logs is a log analytics service that allows you to collect, analyze, and visualize logs from various Azure services and on-premises resources.
Azure Monitor Logs provides insights into your applications and infrastructure, helps you troubleshoot issues, and enables you to optimize performance.
Azure Monitor Logs can collect data from Azure resources, custom applications, and on-premises resources.
You can configure data sources for Azure Monitor Logs through the Azure portal, Azure PowerShell, Azure CLI, or the REST API.
