Setting the maximum number of events in the event repository

In the Events repository section of the Administration Server properties window, you can edit the settings of events storage in the Administration Server database by limiting the number of event records and record storage term. When you specify the maximum number of events, the application calculates an approximate amount of storage space required for the specified number. You can use this approximate calculation to evaluate whether you have enough free space on the disk to avoid database overflow. The default capacity of the Administration Server database is 400,000 events. The maximum recommended capacity of the database is 45 million events.

The application checks the database every 10 minutes. If the number of events reaches the specified maximum value plus 10,000, the application deletes the oldest events so that only the specified maximum number of events remains.

When the Administration Server deletes old events, it cannot save new events to the database. During this period, information about events that were rejected is written to the operating system log. The new events are queued and then saved to the database after the deletion operation is complete. By default, the event queue is limited to 20,000 events. You can customize the queue limit by editing the KLEVP_MAX_POSTPONED_CNT flag value.

To limit the number of events that can be stored in the events repository on the Administration Server:

1. In the main menu, click the settings icon () next to the name of the required Administration Server.

   The Administration Server properties window opens.

2. On the General tab, select the Events repository section. Specify the maximum number of events stored in the database.
3. Click the Save button.
