The following factors determine the load on your Operations Sentinel server when you log messages from Windows systems:
Number of systems that are generating messages
Message rate for each system
Rate at which the event reports are generated for each system
Length of time that log files are kept before they are deleted
The volume of messages and event reports from Windows systems is typically low. To plan your storage requirements, start with a figure of 0.2 megabyte of logging per system per day.
