Items affecting Discovery times
|Table of Contents|
When running a discovery, certain items will affect how fast a discovery runs and processes devices. The below are items to consider when creating and running discoveries.
Obviously the larger the provided subnet, the longer a discovery will take. We generally recommend /24's for efficiency. There is nothing stopping you from using a /16 (65,535 hosts) or even a /8 (16777214 hosts), but do not expect them to complete in a reasonable timeframe. The first section of the discovery script sends the non-responding IP addresses to the Open-AudTI server, so even before actually discovering a responding hosts, this section (on a large subnet) may take minutes or even hours.
When running a discovery against a computer, the rate that the computer can complete the audit script depends on that computer, not on Open-AudIT. Faster computers will complete the audit scritp faster and hence make for a faster discovery.
