System Health: System Event Log
By using the elements in the Selection area of the System Events tab of the System Monitor (SM201530) form, you can narrow the list of events by the sources of the event, the severity level of the event, and the date range.
To view the details of an event, you select the event in the table and the system displays these details in the bottom pane of the form.
Event Sources
On the System Events tab of the System Monitor (SM201530) form, the system logs events triggered by the following sources (with the source of each event noted in the Source column):
- Customization
- Resource Governor
- License
- Push Notifications
- Business Events
- Scheduler
- System
- Commerce
- Active Directory
- Data Consistency
By using the Source multiselect drop-down box in the Selection area of the tab, you can narrow the list of events by selecting any number of sources. By default, the All option is selected.
Severity Levels of Events
On the System Events tab of the System Monitor (SM201530) form, the Level column shows the severity level of each listed event, which is Information, Warning, Error, or Fatal. By selecting an option in the Level box of the Selection area, you can narrow the list of events by severity level. When you select any severity level, the system lists only events with the selected level and higher (that is, more severe) severity levels. The box contains the following options, which are listed from the least to most severe:
- Information (default): Events of all levels are shown in the table; this is the least severe level.
- Warning: The table displays events with the Warning severity and with the higher levels, which are Error and Fatal.
- Error: Events of only the Error and Fatal levels are listed in the table.
- Fatal: The table shows only events with the Fatal level.

Storage of Event Logs
Logged event details are stored in the database. By default, all events older than 30 days are removed from the database. The built-in removal process launches automatically every day and when a website is restarted.
You can change the default frequency of event log deletion by modifying the value of the SystemEventDBSink:CleansingPeriod key in the web.config file. The value should be set in the TimeSpan format; for example, 0.1:0:0 represents the database being cleaned every hour.
Also, if there are performance issues, you can turn off the logging of the events by changing the value for the SystemEventsDbSink:Enabled key to false in the web.config file.
