Good night dear! I installed open audit in my company, initially the application responded quickly, however after a few days it became extremely slow. I made a copy of this virtual machine and realized that the application is fast. Is there any parameter to limit the number of processes? Does the system do discovery all the time?
The application only runs Discovery when you tell it to - either manually or by setting a task.
There is no (and it shouldn't be required) limit to the number of processes.
If you discover a large network (say a /16) discovery will indeed take a long time (that's 65,000 IPs). In that case, I would recommend breaking it up into /24 chunks of addresses.
