When searching data collection event sources it only shows 10 at a time. There must be a way to set that to something more relevant like a 100?
What exactly do you mean? Shows 10 what? From what screen/tab?
For example when your in IDR and your looking at your Event sources you can only display 10 at a time (not sure why I wrote 10). And there is no way to increase that to more than 20.
I see what you mean now. I do not think there is a way to change this, but can be made easier by filtering on the event type to narrow down your search.
