Collecting performance data in a database allows you view the current performance status and performance data history through the web reports, using either graphical charts or output in HTML / CSV format.

EventSentry gives you flexibility by allowing you to configure which counters are written how frequently to the database.

Record in database every ...

Checking this box will record performance counter values at the specified interval. The logging interval has to be equal or higher than the polling interval, since the polling interval defines how often the data is actually being retrieved from the OS.

EventSentry writes the average of the data collected over the logging interval to the database. A shorter logging interval will result in a more accurate representation of the performance data in the database, but will take more more space in the database.

Performance data can be written to one or more databases simultaneously.

For example, if you collect the counter data every 5 seconds, and configure the database logging interval to be 10 minutes, then EventSentry will calculate the average of 120 collected performance values.
