Addon to Track Procs on Other Toons
 

I'm looking for an addon to track procs on other characters in my party. Is that possible? Is there such an app? Thanks.

That depends on a lot of things. What kind of procs are you looking to track? Combat procs, or crafting procs?

Combat. I need to know when trinkets, spells, etc. proc during combat. Thanks!!

Either OmniCD - Party cooldown tracker or WeakAuras 2 should do the trick. If you're familiar with WA I'd recommend sticking with that otherwise go with OmniCD.

Thanks! I'll try those.

oRA3 and BigWigs_CommonAuras will also show class-based procs and cooldowns. Of course, CommonAuras requires BigWigs, while I think DeadlyBossMods has something like that built into the core.

None of the above track item procs. You might be able to add them, but I can't confirm that to be true.
