The highest priority for me with any APM is to view segfaults or any uncaught exceptions. We're currently using the PHP APM and the info we were given is that in order do do this, we'd have to change the agent settings to capture every transaction regardless of length. The main problem here is that with tons of transactions I'm not so sure how well Site24x7 handles this and how much additional server resources this will take up.

It would be very useful if the PHP agent logged all uncaught exceptions or unexpected script exits.

Or do I have this wrong, and there's already a good way to handle and detect this efficiently? I'm used to New Relic where uncaught errors just appear automatically and it's trivial to see exactly what went wrong.
