One thing about this I'd change: C-style for loops are often fencepost errors waiting to happen. When they aren't, they're often easer ways to write it. For example, in this case: 
for (0..@alert) {
  next if (grep /$process[$_]/, @ptable);
  $alerts{$alert[$_]} .= "\n$message[$_]";
}

While I was at it, I changed from $i to $_ for your index var, and from an unless block to a next if. Those are both more matters of taste then perlishness. Slightly more major: I removed a redundant pair of double-quotes, on "$alert$i". Doing that in this case does nothing but slow you down slightly. In some cases, though, it'll force stringifaction, which is rarely what you want. For example, "$obj"->foo() won't call foo on $obj. Instead, it'll try to call foo on somthing like "Class=HASH(0x089742)", and fail.

Confession: It does an Immortal Body good.
