System diagnostics logs are records that capture detailed information about the internal operations of a system, such as errors, performance metrics, and other critical events. These logs are generated automatically by the system to provide insights into:
- Application behavior
- System health
- User interactions
- Error messages
- Performance data
In cloud systems like Microsoft Dataverse and Dynamics 365, diagnostics logs include information about:
- Plugin executions
- Workflow operations
- API calls
- User actions
- Background tasks (e.g., asynchronous jobs)
They are essential for system monitoring, debugging, security auditing, and performance tuning.
2. Why Are System Diagnostics Logs Important?
System diagnostics logs offer several key benefits:
a. Troubleshooting and Issue Resolution
When something goes wrong in a system, diagnostics logs are the first line of defense. They provide detailed error messages, stack traces, and the context surrounding a failure. With the right log information, support teams can:
- Pinpoint errors quickly.
- Identify the root cause of failures.
- Track down configuration issues or performance bottlenecks.
b. Performance Monitoring
Logs can also help identify performance issues by recording how long specific operations take, what resources they consume, and where they slow down. These insights allow administrators and developers to:
- Optimize system performance.
- Resolve slow response times.
- Track resource utilization.
c. Auditing and Compliance
For organizations that must comply with industry regulations (e.g., GDPR, HIPAA), system diagnostics logs serve as an audit trail. They record detailed actions taken by users and administrators, ensuring accountability and transparency.
d. Proactive Monitoring and Alerts
By analyzing system diagnostics logs, administrators can set up automated alerts for potential issues (e.g., when system performance degrades). This allows proactive remediation before users experience significant disruptions.
3. Key Types of System Diagnostics Logs
In Microsoft cloud environments like Dynamics 365 and Dataverse, there are several types of diagnostics logs you may encounter. These include:
a. Application Logs
These logs capture information about the behavior of the application, such as errors, exceptions, and custom trace logs. They help identify problems at the application layer and are invaluable during debugging sessions.
b. Audit Logs
Audit logs capture detailed information about user activities, including login attempts, data access, and changes made to records. They are crucial for security auditing and compliance reporting.
c. Error Logs
Error logs record failures, exceptions, and crash reports. These logs are critical for pinpointing system errors and understanding why specific operations fail.
d. Performance Logs
Performance logs track resource usage, including memory, CPU, and disk usage. These logs provide insights into system bottlenecks, helping developers optimize resource utilization and improve response times.
e. Security Logs
Security logs capture events related to security issues, such as unauthorized access attempts, privilege escalation, and failed logins. They are essential for detecting security breaches and ensuring compliance with industry standards.
4. Enabling System Diagnostics Logs
To effectively use diagnostics logs, you must first enable them within your system. Below are the general steps to enable system diagnostics logs in Microsoft environments like Dynamics 365 and Dataverse.
a. Enabling Plugin Trace Logs
In Dynamics 365, plugin trace logs capture information about plugin execution, helping developers identify errors and issues in custom code. To enable plugin trace logs:
- Go to the Power Platform Admin Center.
- Choose the environment you want to enable logging for.
- Navigate to Settings > Product > Behavior.
- Under Plugin and custom workflow activity tracing, select one of the following:
- Off: Disables logging.
- Exception Only: Logs errors and exceptions.
- All: Logs all plugin activities, including successful execution.
Important: Use “All” only temporarily in production environments, as this can significantly impact performance.
b. Enabling Application Logging
Application logs provide detailed traces about the application’s internal processes. You can enable them in the System Settings in Dynamics 365 or Dataverse.
- In Dynamics 365, navigate to Settings > Administration > System Settings.
- In the Customization tab, enable Application Logging.
- Adjust the log level to either:
- None: Disables application logging.
- Basic: Logs only critical issues.
- Verbose: Logs detailed information for troubleshooting.
c. Enabling Audit Logs
Audit logs capture detailed user and system activities. To enable audit logging:
- Go to Settings > Auditing in Dynamics 365.
- Enable auditing for the desired entities and actions (e.g., create, update, delete).
- Choose which fields to audit (optional).
Audit logs can be accessed through the Audit History interface, where you can search and filter logs for specific activities.
d. Enabling Performance Monitoring
To track system performance, you can use Azure Monitor and Application Insights to collect telemetry data for your Dynamics 365 environment. This helps you monitor:
- Application response times
- Resource utilization
- System throughput
5. Using System Diagnostics Logs
Once diagnostics logs are enabled, you can start using them to troubleshoot issues, monitor performance, and track system events.
a. Accessing and Viewing Logs
You can access and view system diagnostics logs through several interfaces in Microsoft environments:
- Power Platform Admin Center:
- View plugin trace logs, audit logs, and other diagnostic data from within the Admin Center.
- Azure Monitor:
- Collect and analyze telemetry data from Azure-hosted applications.
- Set up alerts for performance degradation or unusual activity.
- Application Insights:
- Use Application Insights to gain deeper insights into application performance, track user interactions, and diagnose errors in real-time.
- Dynamics 365 Interface:
- View application and error logs directly within the Dynamics 365 or Dataverse UI, under the System Settings.
b. Analyzing Logs for Troubleshooting
When an issue occurs, you can filter the logs by time, user, entity, or error message. This helps pinpoint where and why the issue occurred. For example:
- Plugin trace logs provide details on plugin execution, including input parameters, output, and exceptions thrown.
- Audit logs allow you to track user activities and identify whether an issue was caused by an unauthorized user action.
- Performance logs highlight resource consumption, helping you identify slow operations or bottlenecks.
