XMPro Log Events
Introduction
When your XMPro application stops responding, data streams fail, or users report performance issues, log events are your first line of defense for rapid diagnosis. Each XMPro component generates structured log events with specific messages that pinpoint exactly what's happening in your system - from authentication failures and database connection issues to performance bottlenecks and configuration errors. These detailed event references help you interpret what's happening in your system and assess the severity of issues affecting your XMPro deployment.
Log Event References
Each product link below provides complete log event listings with message templates and trigger contexts. Log levels in decreasing severity are critical, fatal, error, warning, information, debug, trace, and verbose.
- App Designer Log Events
- Data Stream Designer Log Events
- AI Log Events
- Subscription Manager Log Events
- Stream Host Log Events
Troubleshooting
Understanding what log events mean for your technical work is essential - these structured events help you quickly identify root causes, set up automated monitoring and alerts, track system performance, generate audit trails, and provide detailed diagnostic information when working with XMPro support.
Log events are crucial for:
- Debugging application issues - Identify specific problems in your XMPro applications
- Monitoring system health - Track the overall health and performance of your XMPro deployment
- Audit trails - Maintain records of system activities and user actions
- Performance analysis - Understand system behavior and identify bottlenecks
Each log event document provides detailed information about events and severity levels.
Tip
These log events can also be exported to your own observability backend over OTLP. When a log event is written during an active trace it carries the trace and span identifiers, so your backend can link it to the request that produced it. See Observability and OpenTelemetry.
Summary
XMPro log events provide structured diagnostic information across all platform components, enabling rapid issue identification and system health monitoring. Use the product-specific event references above to decode system behavior, assess issue severity, and maintain optimal XMPro performance.
