System errors and farm issues
The
widget lists preconfigured system log filters. These system filters are available for each farm component:- [Component] Service Manager Error
- [Component] Service Traffic Manager Error
- [Component] Service Worker Error
You cannot edit the system log filters.
The widget also lists log filters that you have created. You create log filters if you require greater detail than is provided by the system log filters or if you require logging at a different level, such as [Component] Service Manager Information.
Each log filter has one of these logging levels:
- Critical
- Error
- Warning
- Information
- Debug
If you create a filter, select the lowest level at which to log. For example, if you select Error, then events at the Error and Critical levels are logged. To log events at all levels, select Debug.
For log filters that you create, you can specify for how long log entries
are stored, and clear log entries. By default, the log lifetime is 1hour. The maximum is
24 hours. For the system log filters, the log lifetime is Forever
.
When you clear log entries you can clear all entries, or only entries older than a number of days, hours, or minutes that you specify. Click
in the Log Filters widget.Log entries are cached and saved to the server in batches. The size of the cache is specified, for each service, in the Log Queue and Loq Queue Lifetime fields of a service. Select and click the icon of a service in the widget.
You view and administer log entries in the time specified in the user interface, which is typically your local time. The times are translated to Greenwich Mean Time (GMT) when they are saved to the server. For example, a log generated at 4pm Central European Time is stored as 3pm GMT.
In the
widget you can stop or start a selected log filter, and edit the definitions of log filters that you have created.For logs that you create, you can define these options:
- Name
- Description
- Logging level
- Farm component for which to log events
- Service instances to log
- Event IDs to log
- Component IDs to log
Run logs for the shortest time possible to help maintain system performance.
To delete a log that you have created, click the
icon in the widget.During periods when the log service is unavailable, such as during startup, Critical, Error and Warning events are logged to the Windows event log.
