Log Events
View important server-side events in the ObjectBox Admin web interface.
The Log Events page in the ObjectBox Admin web interface displays server-side log events, providing visibility into server operations, warnings, and errors.
Overview
Log events are stored persistently on the server and can be browsed through the Admin UI. Events are displayed in reverse chronological order (newest first) and include detailed information about server activity.
Event Types
Each log event has a type indicating its severity:
Debug
Diagnostic information useful for debugging
Info
General informational messages about normal operations
Important
Significant operational events worth noting
Warning
Potential issues that don't prevent operation
Error
Problems that affected an operation
Crash
Critical failures
Events are color-coded in the UI for quick identification.
