As you design Azure infrastructure solutions and prepare for the AZ-305 exam, one crucial aspect you should focus on is logging. Proper logging solutions offer insight into application health and user behavior, but choosing the correct one for your Azure environment can be quite challenging due to the plethora of options. This post will recommend a reliable logging solution for your Azure environment, highlighting Azure Monitor Logs as a powerful tool for comprehensive functionalities.
Azure Monitor Logs
Azure Monitor Logs is a powerful solution that collects and organizes log and performance data from managed resources. It comes as a feature in Azure Monitor, allowing you to access detailed data inside your applications and infrastructure.
Azure Monitor Logs is centered around Log Analytics workspaces that enable the collection, storage, and analysis of data logs. These workspaces provide a consolidated view across your resources, so you don’t miss critical information even in a large, complex system.
Azure Monitor Logs Core Benefits
Azure Monitor Logs offers several benefits over other logging solutions:
- Comprehensive Monitoring: Azure Monitor Logs not only collects logs but also performance data, enabling comprehensive monitoring of your system.
- Centralized View: Log Analytics workspaces offer a centralized, consolidated view across your resources, essential for complex systems with many moving parts.
- Query Language: It uses Kusto Query Language, allowing you to formulate complex queries to analyze logs and uncover hidden patterns or issues.
- Azure Integration: It integrates well with other Azure services like Azure Security Center, Azure Automation, and more, making it versatile.
- Alerting and Visualization: With Azure Monitor Logs, you can create alerts based on log data or visualize it using Azure Dashboards or Power BI.
Target Scenario for Azure Monitor Logs
With Azure Monitor Logs, you can enable comprehensive logging for critical systems, especially where a centralized view across several resources is essential. For instance, you could use Azure Monitor Logs to monitor an Azure web app’s performance and usage, collect system or application logs from virtual machines, or analyze activity in Azure Active Directory.
Setting Up Azure Monitor Logs
Here is how you can set up Azure Monitor Logs:
- Create a Log Analytics workspace in Azure.
azurecli
az monitor log-analytics workspace create --resource-group myResourceGroup --workspace-name myLogAnalyticsWorkspace
- Connect your resources to the workspace. The process depends on the type of resource; for Azure VMs, you could use the Log Analytics VM extension.
azurecli
az vm extension set --resource-group myResourceGroup --vm-name myVM --name MicrosoftMonitoringAgent --publisher Microsoft.EnterpriseCloud.Monitoring --settings '{"workspaceId": "myworkspaceid"}'
- Use Log Analytics in Azure Monitor to query your logs. The Kusto Query Language (KQL) allows you to carry out complex analysis on the log data.
sql
AppRequests
| where TimeGenerated >= ago(1h)
| where ResultCode !contains "200"
| summarize FailedCount=sum(ItemCount), SuccessCount=1 by Request, Bin=bin(TimeGenerated, 1h)
| render timechart
In conclusion, proper logging is vital for any Azure implementation. Azure Monitor Logs, with its comprehensive monitoring, centralized view, and powerful querying capabilities, is an excellent solution for the AZ-305 exam students and Azure professionals. However, remember that no one tool fits all scenarios, so always consider your specific requirements when choosing a logging solution.
