[Alarm]StreamSize

This parameter defines the amount of data that is included in an event data file.

By default, the setting of Stream Size is 8 (256 Objects), which means that an event data file will contain an hour’s worth of event data for a maximum of 256 database items. If the database contains more than 256 items, it will create extra files for the other database items (with each file containing the event data for a maximum of 256 items).

For many systems, the Stream Size setting of 256 Objects is suitable. However, if you are experiencing reduced performance when displaying and filtering event data, you may need to adjust the Stream Size.

There are several possible causes of slow performance relating to the event data files:

• Your system has a large database (over 100,000 items). The high number of database items can cause an excessive number of files. In this situation, you may be able to improve performance by choosing a higher Stream Size.

• Your system is logging a high number of events. On especially active systems, the volume of events being logged can cause the individual event data files to become large in size (it is recommended that the size of the largest event data file not exceed 5MB). In this situation, you may be able to improve performance by choosing a lower Stream Size.

Note: This parameter can also be applied to a specific cluster or alarm server process. For more information, see Configure Alarm Parameters for a Specific Cluster or Process.
